Fill Rite Fuel Filters: Essential Maintenance Guide for Reliable Performance & Safety

Proper installation, selection, and maintenance of Fill Rite fuel filters are fundamental to protecting your pump investment, ensuring clean fuel delivery, minimizing costly downtime, and upholding operational safety. Neglecting this critical component can lead to severe pump damage, inefficient refueling, fuel contamination issues, and even hazardous situations. Fill Rite fuel transfer pumps are renowned for their durability and effectiveness across numerous industries, from agriculture and construction to fleet management and industrial operations. The filter serves as the first and most vital line of defense, trapping harmful contaminants before they enter and potentially destroy the pump mechanism or contaminate the fuel in the receiving tank. Understanding the types, functions, installation procedures, troubleshooting steps, and maintenance routines for Fill Rite fuel filters is not optional; it's essential knowledge for anyone responsible for fuel transfer equipment. This comprehensive guide provides the practical information you need to maximize the life of your pump and ensure safe, efficient fueling operations.

Understanding the Critical Role of Fill Rite Fuel Filters

Fuel, whether gasoline, diesel, biodiesel, or kerosene, naturally contains contaminants. These range from tiny abrasive particles like dirt, rust, and sediment inevitably introduced during storage, transportation, and handling, to water condensation accumulating in tanks over time, and even microbial growth ("diesel bug"). Without filtration, these contaminants enter the pump.

Particles act like sandpaper against the pump's close-tolerance components, such as pistons, valves, and seals. This abrasive action leads to accelerated wear, scoring of metal surfaces, deterioration of rubber seals, and eventual degradation of pump performance. This manifests as decreased flow rates, increased noise, overheating, and ultimately, catastrophic pump failure requiring expensive repair or replacement.

Water poses a different threat. It promotes corrosion within the pump's internal metal parts, dilutes fuel reducing its lubricating properties (critical for diesel pumps), and provides an environment where bacteria and fungi thrive, forming sludge that clogs fuel systems downstream. In cold weather, water can freeze, completely blocking flow.

A Fill Rite fuel filter physically traps these contaminants. Installed on the inlet side of the pump (suction side), it screens the fuel before it enters the pumping mechanism. By capturing these harmful elements, the filter directly protects the pump from internal damage caused by abrasives and water-induced corrosion. This protection is vital for maintaining pump efficiency, ensuring a consistent flow rate during refueling tasks, extending the pump's operational lifespan significantly, and preventing premature, costly breakdowns that disrupt operations. Essentially, the filter is a small, relatively inexpensive component safeguarding a much larger, critical investment – the pump itself.

Identifying Common Fill Rite Fuel Filter Models and Types

Fill Rite offers a diverse range of fuel filters designed to match specific pump models, flow rates, fuel types, and contaminant challenges. Knowing the right filter type is crucial for effective protection and optimal pump performance. Here's a breakdown of the primary categories:

1. Spin-On Cartridge Filters: This is the most prevalent and user-friendly type for many Fill Rite applications.

   • Construction: Consists of a replaceable filter element (cartridge) housed inside a durable metal canister. The canister has inlet and outlet ports and threads onto a matching filter head permanently mounted on the pump housing.
   • Media: The filter cartridge contains specially designed media to trap contaminants. Common types include:
     • Paper/Cellulose: Economical option providing good filtration for larger particles (typically 30-40 microns). Suitable for many standard applications but less effective with finer contaminants and water.
     • Synthetic Blend: Combines cellulose with synthetic fibers (like glass or polyester) for improved efficiency and dirt-holding capacity. Offers finer filtration (often 10-30 microns) while maintaining good flow rates.
     • Pure Synthetic (e.g., Microglass): Top-tier performance. Provides the finest particle removal (down to 10 microns or less) and superior water separation due to specialized hydrophobic coatings on the fibers. Offers the highest dirt-holding capacity and longest service life, especially in challenging conditions like biodiesel use or contaminated fuel sources. Highly recommended for critical applications and maximum pump protection.
   • Water Blocking Feature: Many Fill Rite spin-on filters, especially synthetic ones, incorporate a "water block" feature. This involves treated media that repels water droplets. As water accumulates, it reaches a saturation point and is pulled by gravity to a reservoir at the bottom of the filter bowl via a special hydrophobic drainage layer surrounding the media. This allows accumulated water to be drained off periodically without contaminating the clean fuel side. Crucial for preventing water from passing into the pump.
   • Advantages: Easy and clean replacement. Wide availability. Consistent quality. Reliable sealing. Optional water drain valves available on many models.
   • Application: Widely used on Fill Rite piston pumps (like FR series), rotary vane pumps (like V series), and some gravity feed systems.

2. Bowl-Type Inline Filters: A common design, especially prevalent in older models or specific high-flow applications.

   • Construction: Comprises a clear (or opaque) bowl (usually plastic or glass) screwed onto a filter head. Inside the bowl sits a replaceable filter element. An O-ring seal between the bowl and head creates a leak-proof connection.
   • Media: Similar to spin-on filters – cellulose, synthetic blends, or pure synthetic media are available depending on the specific element part number. Also often includes water blocking and coalescing capabilities depending on the media choice.
   • Advantages: Visual inspection is possible through the clear bowl (if equipped), allowing you to easily see accumulated water or heavy sediment contamination. Often allow slightly higher flow rates than spin-ons with similar micron ratings. Can be slightly more economical for the element itself.
   • Disadvantages: Risk of breakage if made of glass/plastic. Requires care during assembly to align the bowl correctly and avoid cracking or over-tightening which can damage the seal. O-ring must be in good condition and lubricated properly to prevent leaks. Replacing the element can be messier than a spin-on, especially if the bowl contains fuel and contaminants.
   • Application: Found on many Fill Rite diaphragm pumps (like D series), some centrifugal pumps, and certain older models across types.

3. In-Line Fuel Strainers: A simpler, more basic level of protection.

   • Construction: Typically a metal or plastic body containing a simple mesh screen (often brass or stainless steel).
   • Function: Primarily designed to catch only large debris like wood chips, bugs, leaves, or large rust flakes. Mesh size is coarse (100 microns or larger).
   • Role: Does not replace a full-fledged filter. Used as a pre-filter or pre-strainer, installed upstream of the main filter (usually directly at the tank outlet or suction pipe entrance). Its purpose is to capture large contaminants that would rapidly clog or damage the finer media in the main filter. Particularly useful in environments prone to larger debris (e.g., construction sites, farms, marine environments) or with older storage tanks that might shed rust flakes.
   • Application: Used in conjunction with primary filters on almost any Fill Rite pump setup where coarse contamination is a risk.

Critical Factor: Micron Rating
Regardless of type, the micron rating defines the filter's efficiency. It indicates the size of the smallest particles the filter is designed to trap with high efficiency (e.g., Beta ≥ 75 meaning it traps 98.7% or more of particles at that size). Common Fill Rite filter ratings range from 100 microns (roughing/pre-filter) down to 10 or even 5 microns (high-efficiency). Always consult your pump's specific manual or the Fill Rite part number cross-reference guide. Using a filter with a micron rating too fine for your pump model can severely restrict flow and cause cavitation (see troubleshooting section). Conversely, a filter too coarse offers inadequate protection. As a general rule for Fill Rite pumps:

• Piston Pumps: Commonly use 10-30 micron filters (synthetic media recommended).
• Rotary Vane Pumps: Commonly use 10-30 micron filters (synthetic media recommended).
• Diaphragm Pumps: Often handle slightly larger micron ratings (e.g., 30-60 microns), but consult the manual.
• Centrifugal Pumps: Might use ratings from 30-100 microns depending on design and application. Never assume - check the manual.

Step-by-Step Guide: Installing a Fill Rite Fuel Filter Correctly

Proper installation is paramount. Mistakes can lead to air leaks, fuel leaks, insufficient flow, and pump damage. Follow these steps carefully:

1. Identify the Correct Replacement Filter:

   • Never Guess. Rely on the pump's model number and serial number. Locate these on the pump's identification tag/sticker.
   • Consult the official Fill Rite parts manual for your specific pump model.
   • Use authorized Fill Rite part numbers obtained from the manual or official retailers/distributors (e.g., FRF filters for spin-ons). Using non-genuine or incompatible filters voids warranties and risks poor performance or damage.
   • Critical: Verify the micron rating and flow rate capacity match your pump's requirements.

2. Choose the Correct Location:

   • Fill Rite filters are ALWAYS installed on the suction side (inlet side) of the pump, BEFORE the fuel enters the pumping mechanism. This protects the pump.
   • Install the filter assembly as close to the fuel supply tank outlet as practical, but ensure it's accessible for maintenance and doesn't create a trip hazard. Vertical installation (fuel flow down through filter into pump) is generally preferred for optimal air and water purging. Avoid sharp bends immediately before or after the filter.
   • For pre-strainers, install directly at the tank outlet connection or on the submerged end of the suction pipe inside the tank (consult manual).

3. Prepare the Installation (Spin-On Type):

   • Ensure the fuel supply is off (tank valve closed).
   • Clean the area around the pump's filter head mounting surface thoroughly. Remove any dirt or old gasket material.
   • Lubricate the O-ring or gasket supplied with the new filter using a small amount of clean fuel. Never install a filter dry. This ensures a proper seal and prevents the rubber from binding or tearing during tightening.
   • Important: Inspect the filter head threads for damage. Clean if necessary.

4. Install the Filter (Spin-On Type):

   • Carefully screw the new filter onto the filter head by hand. Align it properly and turn clockwise.
   • Once the filter's gasket contacts the filter head mounting surface, hand-tighten it firmly. Do not use tools at this stage.
   • Give the filter an additional 3/4 to 1 full turn with your hands. If extremely tight access requires tools, use a filter wrench gently only after hand-tightening, applying force only to achieve an additional 3/4 turn maximum. Over-tightening distorts the housing or crushes the seal, leading to leaks or housing damage. Under-tightening causes leaks.

5. Prepare the Installation (Bowl-Type):

   • Ensure the fuel supply is off. Place absorbent material below the filter assembly.
   • Carefully unscrew the bowl from the filter head (normally counter-clockwise). Be cautious as fuel and debris may spill.
   • Remove the old element. Discard it properly.
   • Clean the bowl meticulously using clean, lint-free cloths and clean fuel. Inspect for cracks or clouding. Replace the bowl if damaged.
   • Clean the filter head surface and threads. Inspect the O-ring groove. Remove any debris.
   • Lubricate the new large O-ring (supplied with element kit or bowl kit) with clean fuel. Install it properly into the groove on the filter head. Do not reuse old O-rings.
   • Remove the small protective caps from the ends of the new element (if present). Place the new element into the clean bowl, ensuring it seats properly.

6. Install the Bowl (Bowl-Type):

   • Align the bowl with the filter head carefully.
   • Start threading the bowl onto the head by hand (clockwise). Ensure it threads straight to avoid cross-threading.
   • Hand-tighten the bowl firmly until snug. Avoid excessive force, especially with plastic bowls.
   • Recommended: Use a strap wrench (fabric strap or rubber pad type) to provide slight additional tightening if needed to prevent leaks. Apply minimal force – overtightening cracks plastic bowls instantly.

7. Final Steps for All Types:

   • Double-check all connections upstream and downstream of the filter assembly for tightness.
   • If a filter has a drain valve at the bottom (common on water-blocking models), ensure the valve is closed tightly.
   • Slowly open the fuel supply valve. Carefully inspect the entire filter assembly, all connections, and surrounding areas for any signs of leakage. Pay close attention to the seal areas (base of spin-on, bowl rim on bowl-type). Fuel leaks are a severe fire hazard!
   • If a leak is observed, immediately close the fuel supply valve. Identify the source. Spin-On: Try slightly tightening (no more than 1/8 turn). If still leaking, remove filter, check gasket/O-ring, re-lubricate, and reinstall. Bowl-Type: Try slight tightening with strap wrench. If still leaking, depressurize, remove bowl, inspect O-ring position and condition (replace if damaged/nicked), re-lubricate, and reassemble. Major leaks or damaged components require immediate replacement before use.

Recognizing Problems: Symptoms of a Clogged or Failing Fill Rite Fuel Filter

Your pump provides clear signals when filter performance is compromised. Ignoring these signs risks pump damage. Be vigilant for:

1. Drastically Reduced Flow Rate (Slow Pumping): This is the most common symptom. If pumping takes significantly longer than usual to fill a container that previously filled quickly, the filter is likely clogged with trapped contaminants restricting fuel flow. Reduced flow is often the first noticeable issue.
2. Pump Strain & Overheating: A clogged filter forces the pump to work much harder to pull fuel through the restriction. This manifests as the pump motor running louder than normal (more laboring sound) and the pump housing becoming noticeably hotter to the touch during operation. Excessive heat accelerates wear on internal components and seals.
3. Pump Stalling or Surges: Severe restriction can cause intermittent stalling – the pump motor stops running under the load, only to start again briefly when load decreases. You might also experience uneven flow or surging – the pump seems to pulse or the flow rate fluctuates dramatically. These indicate a critical flow restriction.
4. Cavitation Noise: Cavitation occurs when the pump cannot get fuel fast enough through the clogged filter. Air bubbles form and violently collapse within the pump chamber due to extreme low pressure on the suction side. This produces a distinct, loud, knocking, rattling, or gravel-like noise, especially noticeable at higher flow rates. Cavitation is extremely damaging to pump internals.
5. Inability to Prime: A pump that won't prime, or loses prime frequently, often points to a significant air leak or a blocked flow path. A severely clogged filter preventing fuel from reaching the pump effectively prevents priming. Always check the filter condition if facing priming issues.
6. Visible Contamination in Bowl-Type Filters (If Equipped): A significant advantage of clear bowls. If you see excessive sediment build-up at the bottom, a dark element, or a distinct layer of water separating below the fuel (especially if it's filling more than the bottom 1/4 inch), the filter needs immediate attention.
7. Fuel Leaks Around the Filter Assembly: While leaks can have various causes (faulty O-ring, cracked bowl, loose connection), a clogged filter significantly increases pressure on the suction side of the pump and can sometimes exacerbate minor seal weaknesses, making leaks more apparent. However, leaks demand investigation regardless of clogging suspicion.

Troubleshooting Common Fill Rite Fuel Filter Issues

Encountering problems? Follow these systematic steps to diagnose filter-related issues:

1. Symptom: Slow Pumping / Reduced Flow:

   • Step 1: Visually inspect the filter. For bowl-type: Look for sediment/water. Check if inlet strainer (if equipped) is blocked. For spin-on: Check manufacturing date (older units > 1 yr in storage might be compromised internally even if unused).
   • Step 2: Check for flow restrictions before the filter. Ensure tank vent is clear, fuel cap vent isn't blocked, tank outlet valve is fully open, suction line is not kinked or collapsed, tank fuel pick-up tube screen isn't clogged (if applicable), and the fuel level is adequately above the inlet to prevent starvation.
   • Step 3: If Steps 1 & 2 are clear, the filter is likely clogged. Proceed to replace the filter.

2. Symptom: Excessive Noise (Growling/Rattling) / Pump Runs Hot:

   • Step 1: Listen carefully. Is the noise a distinct knock/rattle? (Suggests cavitation). Or is it just a strained motor sound? Check pump housing temperature cautiously.
   • Step 2: Immediately check all connections on the suction side (tank outlet to pump inlet). Tighten slightly if any suspect fittings. Look for visible leaks. Air leaks introduce air into the suction line, which can cause noise and overheating similar to a clogged filter. Use soapy water solution sprayed on connections while pump runs to look for bubbles forming (indicates air being sucked in).
   • Step 3: If no air leaks found, suspect a clogged filter restricting flow and causing cavitation/overheating. Proceed to replace the filter.

3. Symptom: Pump Loses Prime / Won't Prime:

   • Step 1: Check for large air leaks using Step 2 above (soapy water test is very effective here). Pay special attention to connections before the filter, the filter itself, and the pump inlet.
   • Step 2: Ensure the suction line is filled with fuel. Does the system hold prime if the discharge nozzle is held above the pump? If not, there's a leak allowing fuel to drain back. Check valves must hold. Check that all seals (like the filter) are intact.
   • Step 3: Visually check the filter for severe clogging (bowl-type). A completely blocked filter prevents fuel from reaching the pump, making priming impossible.
   • Step 4: Check for a clogged tank vent or incorrect nozzle height above fuel level. Ensure the suction hose isn't excessively long or oversized for the pump.
   • Step 5: If Steps 1-4 don't resolve it, replace the filter.

4. Symptom: Water Contamination Concerns:

   • Step 1: If using a filter with a clear bowl, visually check the bottom for water accumulation. If present, close the fuel supply, carefully open the filter's drain valve (ensure you have a container ready), and drain the water out until clean fuel appears. Close drain valve tightly.
   • Step 2: If the problem recurs frequently, your fuel source likely has excessive water. Investigate tank integrity, vent points, condensation control measures (desiccant vents?), source fuel quality, or consider a primary bulk tank filter/water separator.
   • Step 3: Filters with pure synthetic microglass media offer superior water separation and blocking. Consider upgrading if water is a persistent issue. Important: Drain water from filters with drain valves regularly (at least monthly in damp climates or if water appears).

Important Note: If replacing the filter resolves the problem, it confirms the diagnosis. If the problem persists after filter replacement, investigate other potential causes like air leaks, faulty valves, tank issues, incorrect suction line, blocked discharge nozzle/nozzle screen, electrical problems (e.g., low voltage to a motor), or internal pump damage caused by prolonged operation with a clogged filter.

Implementing a Proactive Fill Rite Fuel Filter Maintenance Plan

Reactive maintenance (only changing the filter when the pump fails) leads to avoidable downtime and repair costs. A proactive schedule is essential:

1. Base Replacement Intervals on Usage & Environment (Critical): There is no single magic mileage/time interval that fits all. Frequency depends heavily on:

   • Fuel Quality: Clean fuel from reliable sources requires less frequent changes than "dirty" fuel from questionable vendors, old tanks, or high-contamination environments (like construction sites).
   • Pump Usage: Frequent, high-volume users need more frequent changes than occasional users.
   • Fuel Type: Biodiesel blends often require more frequent filtering due to increased solvent properties and potential microbial growth. Diesel generally needs tighter filtration than gasoline.
   • Environmental Factors: High humidity or temperature swings lead to condensation (water) in tanks requiring more frequent attention. Dirty/dusty environments increase particulate load.
   • Observation: Routinely check bowl-type filters. Note performance changes (e.g., flow rate slowing down). This guides your specific schedule.

2. Establish a Realistic Schedule: While Fill Rite often recommends "annually or every 50 hours of operation" as a baseline for preventative maintenance, use this as a starting point only.

   • High Risk / High Use: Consider every 25-50 hours of operation or every 3-6 months.
   • Moderate Use: Every 50-100 hours or annually.
   • Low Use: Annually at a minimum. Crucially, never exceed 2 years, even on very lightly used equipment. Filter media degrades over time, and accumulated stagnant water causes corrosion inside the filter housing itself, introducing new contaminants into your system.
   • Document: Keep a simple log (date, hours run, filter part # changed).

3. Essential Inspection Routine:

   • Before Each Major Fueling Session: Visually inspect the filter assembly for obvious damage (cracks, dents), severe corrosion, or visible leaks. Listen for abnormal pump sounds when starting.
   • Weekly/Monthly (Based on Usage):
     • Check bowl-type filters visually for water/sediment levels.
     • Drain water from filters equipped with a drain valve. Close drain valve securely after draining.
     • Verify the pump achieves expected flow rates during operation.
   • After Prolonged Storage (e.g., over winter): Inspect filter housing closely for damage. Inspect suction lines for cracks. Consider replacing the filter before putting equipment back into active service, especially if stored for over 6 months.

4. Stock Replacement Filters: Always keep at least one spare, correct filter cartridge or element for your specific Fill Rite pump model on hand. Downtime waiting for a filter delivery can be costly and frustrating. Store spares in their original packaging in a clean, dry location away from extreme temperatures or UV light to prevent premature degradation.

5. Disposal: Dispose of used fuel filters responsibly. They contain contaminated fuel, water, and hazardous materials. Follow local environmental regulations. Many service centers accept used filters for recycling. Never throw a saturated fuel filter into regular trash.

Prioritizing Safety During Filter Changes and Fuel Handling

Fuel handling involves inherent fire and health risks. Safety protocols are non-negotiable:

1. Work in a Well-Ventilated Area: Perform filter changes outdoors or in a large, open garage with doors open. Fuel vapors are toxic and highly flammable. Adequate ventilation dissipates vapors.
2. No Ignition Sources: Absolutely no smoking. Ensure pilot lights, flames, sparks (including electrical tools, switches, extension cords), static electricity generators are at least 25-50 feet away. Put phones away. Fuel vapors are heavier than air and can travel long distances to an ignition source.
3. Grounding and Bonding: Static electricity is a major ignition hazard. Before handling fuel, filter components, or opening tanks:
   • Ground the Fuel Container or Tank: Connect the tank or fuel container to a true earth ground point using an approved grounding cable/clamp.
   • Bond Components: Connect the fuel supply tank and the receiving tank (or dispensing nozzle) together using a bonding cable before beginning transfer operations or opening containers. This ensures any static charge is safely equalized, preventing sparks. Maintain the bond until the operation is complete and the system is closed.
   • Ground the Pump Assembly: Ensure the pump itself is properly grounded via its electrical connection or a separate grounding wire.
4. Use Approved Safety Equipment:
   • Wear chemical-resistant gloves (nitrile, neoprene) designed for fuel contact to prevent skin absorption and irritation.
   • Wear ANSI-approved safety glasses or a face shield to protect eyes from fuel splashes.
   • Have a Type ABC fire extinguisher rated for flammable liquids within immediate reach (5-10 feet) before starting any task involving open fuel systems.
   • Use spill containment pads or drip pans positioned under the work area to catch drips.
5. Avoid Spills & Contain Leaks:
   • Work slowly and deliberately when opening filter bowls or disconnecting lines.
   • Keep absorbent materials (clay-based pads, socks, kitty litter) nearby to instantly contain small spills.
   • If a spill occurs beyond immediate containment capabilities, evacuate the area immediately and call emergency services.
6. Personal Hygiene: Wash hands and exposed skin thoroughly with soap and water after handling fuel or filters, even if wearing gloves. Avoid touching your face while working. Contaminated clothing should be removed and laundered separately promptly.
7. No Power: Always unplug electric pumps (or disconnect battery cables for DC pumps) before servicing. This prevents accidental startup while your hands are near moving parts or open fuel lines.
8. Release Pressure: Before disconnecting any fuel line or opening a bowl-type filter, ensure all pressure in the system is safely relieved. Close the tank valve first.

Selecting the Best Fill Rite Fuel Filter Replacement

Choosing the right replacement filter impacts performance and longevity:

1. Mandatory: Genuine Fill Rite Filters: Always purchase filters by the correct Fill Rite part number specific to your pump model. These are engineered for precise fit, flow rates, pressure tolerances, and sealing requirements.
2. Myth vs. Reality: Micron Ratings: While a lower micron number indicates finer filtration, using a finer filter than your pump is designed for causes harmful flow restriction. Never "upgrade" to a 10-micron filter if the pump manual specifies 30 microns unless explicitly approved by Fill Rite for your specific model. Conversely, a filter too coarse won't protect sufficiently. Stick with the OEM recommended micron rating.
3. Media Choice - Performance Matters: Within the correct micron rating, you often have media options:
   • Paper/Cellulose: Adequate for very clean fuel and light-duty use. Least expensive option.
   • Synthetic Blend: Better balance of cost, filtration efficiency, and dirt-holding capacity. Good general-purpose choice.
   • Pure Synthetic (Microglass): Significant Performance Advantage: Offers the best protection. Filters finer particles efficiently, separates water dramatically better due to hydrophobic treatment, holds significantly more contaminant before clogging, resists media degradation from biofuels, and typically provides longer service life, offsetting the higher initial cost for demanding applications or critical equipment. The investment in high-performance media pays off in reduced filter change frequency and significantly better pump protection.
4. Water Separation & Blocking: For reliable operation, choose a filter explicitly designed with water blocking technology (standard on Fill Rite FRF series spin-ons). This prevents water passage even when saturated, allowing it to be drained safely.
5. Drain Valve: Filters with an integrated drain valve are highly recommended. They allow for quick, safe draining of accumulated water without removing the filter, facilitating regular maintenance and preventing water from reaching damaging levels.

Conclusion: Filter Maintenance is Investment Protection

Ignoring your Fill Rite fuel filter is never an option. It is an essential, active component, not just a passive accessory. By understanding its vital function, selecting the correct part, installing it meticulously, monitoring its condition through performance and visual cues, troubleshooting problems systematically, maintaining it proactively based on your specific conditions, and rigorously adhering to safety protocols during any maintenance activity, you ensure reliable fuel transfer operations. This diligence directly translates into maximizing the service life of your Fill Rite pump, preventing costly breakdowns and repairs, minimizing operational downtime, protecting the quality of your stored fuel, and most importantly, upholding a safe working environment for everyone involved. View the filter and its regular care as fundamental insurance for your valuable fuel-handling equipment. Always consult the specific Fill Rite owner's manual for your pump model and replace filters using genuine Fill Rite parts for guaranteed performance and safety.
