98 Lincoln Town Car Fuel Pump: Your Complete Guide to Diagnosis, Replacement & Restoration

Dealing with a failing or failed fuel pump in your 1998 Lincoln Town Car can leave you stranded, but it doesn't have to be a crisis. This comprehensive guide provides everything a typical owner needs to confidently identify symptoms, safely replace the pump, and ensure their iconic Town Car returns to smooth, reliable operation. Focusing on practicality and safety, we'll walk you through the entire process, from recognizing the warning signs to selecting the right part and performing the replacement correctly.

Understanding Your Town Car's Heart: The Fuel Pump System

The fuel pump is absolutely critical to your Town Car’s operation. Located inside the fuel tank, its job is simple yet vital: draw fuel from the tank and deliver it under high pressure to the engine's fuel injectors. The Engine Control Module (ECM) precisely regulates this pressure, but it all starts with the pump.

  • The Pump Itself: An electric motor spins an impeller, creating suction to pull fuel in and pressure to push it out through the fuel lines.
  • The Fuel Sender: Attached to the pump assembly is the fuel level sender unit. This component uses a float arm that moves with the fuel level, changing resistance to signal the gauge on your dashboard.
  • The Strainer/Sock: A mesh filter attached to the pump's inlet prevents larger debris in the tank from entering the pump.
  • The Assembly: Housings, seals, wiring connectors, and mounting components integrate these parts into a single unit designed for secure installation in the top of the tank.
  • The Fuel Filter: While separate from the in-tank assembly (typically located along the frame rail near the tank), a clogged fuel filter creates excessive resistance, forcing the pump to work harder and potentially leading to premature failure. Always consider its condition.

Recognizing the Symptoms: When Your 98 Town Car's Fuel Pump Cries for Help

A failing fuel pump rarely dies instantly without warning. Pay attention to these common symptoms, especially if multiple occur or progressively worsen:

  1. Hard Starting or Extended Cranking: The most frequent early sign. If the pump is weak, it takes longer to build the necessary pressure (around 35-40 PSI at the fuel rail) for the engine to start. You turn the key, the starter cranks longer than normal, and then it finally catches. This often gets noticeably worse when the engine is hot.
  2. Engine Sputtering, Hesitation, or Power Loss Under Load: As you accelerate, merge onto a highway, or climb a hill, the engine demands more fuel. A failing pump struggles to keep up, causing the engine to stumble, hesitate, jerk, or simply lack its signature Town Car power. The problem usually appears first at higher RPMs or during significant throttle opening.
  3. Engine Stalling: A pump nearing complete failure may cut out intermittently, especially under the stress described above (high load or heat). The car might start again after cooling down briefly, only to stall again later. This is a severe warning sign.
  4. Whining or Humming Noise from the Fuel Tank: While fuel pumps normally produce a low hum, a loud, high-pitched whining or groaning noise coming from the rear of the car (especially while idling or under load) is a strong indicator the pump's motor is failing. Listen near the fuel filler area or rear seat floor.
  5. Engine Refuses to Start: The ultimate symptom. The starter cranks the engine normally, but it doesn't fire. This typically means the pump is completely dead, a fuse or relay has blown due to pump failure, or it has lost electrical power (check these too!). No fuel pressure equals no start.

Before You Blame the Pump: Essential Diagnostic Checks (Safety First!)

Replacing a fuel pump is a significant task, especially because it requires dropping the fuel tank. Performing preliminary checks is crucial to verify the pump is indeed the culprit and avoid unnecessary work:

  1. Check the Fuel Pump Inertia Switch: A safety feature designed to cut power to the pump in a collision. It can sometimes trip due to a hard bump or even accidentally resetting it. Locate it (usually behind the passenger side kick panel near the firewall - consult your manual for exact location). Press the reset button firmly. If the car starts immediately after, this was your simple fix! If it doesn't, or if it trips again soon after, there's likely another problem causing it to trigger (like a wiring short near the pump).
  2. Listen for Initial Prime: Turn the ignition key to the "ON" position (not start). You should hear a distinct humming or buzzing sound from the rear of the car (under the rear seat area) for about 2-3 seconds. This is the pump priming the system. No prime sound? This points strongly to an electrical issue or a dead pump. Do you hear it? The pump is at least getting some power. Proceed to step 3 or 4.
  3. Check Fuel Pump Fuse and Relay: A blown fuse or a faulty relay is common. Locate your fuse box(es) (under the hood, and likely the interior fuse panel near the driver's side kick panel - consult your manual). Find the fuel pump fuse (labeled clearly like "FP," "F/Pump," "Fuel," etc.) and the fuel pump relay (often in the same box). Pull the fuse and inspect the metal strip - if it's broken, replace it with one of the exact same amperage rating. Swap the fuel pump relay with another relay of the identical type in the box (like the horn relay). If the car suddenly starts, you found the bad relay.
  4. Verify Fuel Pressure: This is the most definitive mechanical test. You need a fuel pressure test gauge kit compatible with Schrader valves (your fuel rail has one that looks like a tire valve stem). CRITICAL SAFETY: Relieve fuel pressure first! Find the fuse box fuse for the fuel pump and remove it. Start the engine and let it die - this uses up the pressure remaining in the line. Crank it again for a couple of seconds. Wrap a rag around the Schrader valve and carefully press the center pin to release any tiny remaining pressure. Attach your gauge. Now, either turn the key to "ON" to activate the prime cycle, or have an assistant crank the engine while you watch the gauge.
    • You must see pressure rapidly rise to between 35 and 40 PSI on a 98 Town Car and hold steady for several minutes after the pump stops priming/cranking stops. Sustained pressure is vital.
    • Low or No Pressure: Confirms a fuel delivery problem (pump, clogged filter, bad pressure regulator, but pump is prime suspect).
    • Pressure Drops Quickly: Points to a leak (bad fuel pressure regulator, injector, or line) or a failing check valve inside the pump assembly.
  5. Voltage Check at Pump Connector (Advanced): This verifies if power is reaching the pump. Accessing the connector usually requires lowering the tank partway or accessing it under the car near the tank top. Extreme Caution Needed! Ensure no fuel leaks are present. Disconnect the harness. Use a digital multimeter. With the key turned to "ON," you should see battery voltage (around 12V) between the pump power and ground terminals for the 2-3 second prime period. If voltage is correct here but the pump doesn't run (and you confirmed ground), the pump is dead. If no voltage, trace the circuit backwards (inertia switch, relay, fuses, wiring).

Gathering Your Arsenal: Parts & Tools for the Job

Replacing a Town Car fuel pump requires the right parts and tools. Preparation makes the job smoother and safer.

Essential Parts:

  1. Complete Fuel Pump Module Assembly: Strongly recommended over just replacing the pump motor alone. This includes:
    • New Electric Fuel Pump
    • New Fuel Level Sender Unit
    • New Strainer/Sock Filter
    • New Locking Ring (Critical! Old ones get brittle/deformed)
    • New Large O-Ring/Gasket for tank seal
    • New Sealing Washers for fuel lines (if applicable)
    • New Sending Unit/Sock Float Arm (often integrated) Purchasing the complete assembly ensures all wear components are new, the electrical connections are fresh, and you have the correct parts designed to work together. It significantly reduces the risk of leaks and future failures. Reusing an old sender unit or lock ring is a common cause of repeat tank drops. Trusted brands for Town Cars include Bosch, Delphi, Motorcraft (Ford OEM), ACDelco, Denso, Carter, and Spectra Premium.
  2. Fuel Filter: Always replace the external fuel filter during a pump replacement. It's cheap insurance and ensures the new pump isn't strained by old restrictions.
  3. High Quality Fuel: Ensure you have at least 1/4 tank or less of fuel (preferably less makes the tank lighter/safer to handle). Plan to fill with fresh, quality gasoline afterward.

Essential Tools & Supplies:

  • Floor Jack & Heavy-Duty Jack Stands (4 stands recommended for stability) - Vehicle must be secure!
  • Wheel Chocks
  • Safety Glasses & Nitrile Gloves
  • Wrench Set (Metric & SAE, including large adjustable wrenches - at least 24mm or 15/16" for line fittings and lock ring)
  • Full Socket Set (Metric & SAE, extensions, universal joints, breaker bar)
  • Torque Wrench (critical for proper sealing)
  • Screwdrivers (Flat & Phillips)
  • Pliers (Standard & Linesman)
  • Trim Removal Tools (Plastic wedges/pry tools)
  • Fuel Line Disconnect Tools (The correct size for your fuel line fittings - often 3/8" & 5/16")
  • Wire Brush
  • Clean Shop Rags & Brake Cleaner (for cleaning connections/outside of tank)
  • Drain Pan (large enough for any spilled fuel)
  • Fire Extinguisher (ABC Type - MUST be readily accessible near the workspace at all times)
  • Shop Light or Good Headlamp
  • Penetrating Oil (Like PB Blaster or Liquid Wrench - for potentially stuck tank straps or fittings)
  • New Hose Clamps (Small fuel-safe clamps if needed for vent lines)
  • Thread Sealant (Gasoline-Resistant - like Permatex High-Temp Thread Sealant for bolt threads)

SAFETY FIRST: Non-Negotiables for Fuel Pump Replacement

Working with gasoline is inherently dangerous. Ignoring these rules can lead to severe injury or death.

  • No Open Flames or Sparks EVER: Prohibit smoking, welding, grinding, or anything creating sparks near the work area. Gasoline vapors are extremely flammable and can travel unseen distances to an ignition source. Work in a well-ventilated space if possible (open garage door).
  • Work Outside or Extremely Well-Ventilated Area: Perform the job outdoors if feasible. If indoors, ensure strong ventilation - open all doors, use fans to move air OUT. Gasoline vapors sink and are explosive.
  • Relieve Fuel Pressure Before ANY Line Disconnection: (See procedure in Diagnostic Checks Step 4). Failure to do this can spray high-pressure fuel everywhere.
  • Disconnect Negative Battery Terminal: Prevents accidental sparks from electrical components during disassembly. Do this after relieving fuel pressure if you need power for priming diagnostics.
  • Fire Extinguisher Must Be Within Reach: ABC-type extinguisher is mandatory. Know how to use it quickly.
  • Protective Gear:
    • Safety Glasses: Essential to protect eyes from fuel spray, dirt, rust particles.
    • Nitrile Gloves: Protects skin from prolonged gasoline contact (which is harmful) and improves grip.
  • Ground Yourself: Before touching the inside of the fuel tank or the pump assembly (especially sensitive electronics on newer senders), touch bare metal on the car's chassis to discharge any static electricity. Static spark inside the tank can ignite vapors.
  • Minimize Fuel in Tank: Drive the car until very low on fuel or safely siphon most fuel out first (check regulations for safe siphoning). A full tank is extremely heavy and more dangerous to handle.
  • Avoid Tank Denting: Dropping the tank or hitting it hard can compromise its integrity. Handle carefully.
  • Seal Fuel System Quickly: Once the old pump is out, immediately install the new module and seal the tank to minimize the time the tank is open. Wipe any spilled fuel off the tank top meticulously before installation.
  • Tighten Connections to SPEC: Use a torque wrench on critical sealing points (lock ring, fuel line fittings, sender retaining bolts if used). Overtightening can crack parts; undertightening leads to leaks. Follow manufacturer specs.

Step-by-Step Replacement Guide: Accessing the Fuel Tank

  1. Final Safety Prep: Park on level, solid ground. Apply Parking Brake. Chock the Front Wheels FIRMLY. Relieve Fuel Pressure. Disconnect NEGATIVE Battery Terminal. Double-check fire extinguisher location. Put on glasses and gloves.
  2. Raise and Secure the Vehicle: Jack up the rear of the vehicle using the manufacturer recommended jacking points (consult manual - usually along the frame rails near the back). Position heavy-duty jack stands securely under the rear subframe or dedicated stand points. Ensure the vehicle is rock-solid before crawling under. NEVER work under a vehicle supported only by a jack. Lower the vehicle gently onto the stands. Remove rear wheels for better access if needed (recommended).
  3. Access the Fuel Tank: The 98 Town Car's fuel tank is located centrally between the rear wheels, protected by two metal support straps.
  4. Disconnect Fuel Lines & Electrical: Locate the wiring harness connector and fuel lines attached to the pump module on the top of the tank.
    • Electrical Connector: Find the connector (usually clipped into a bracket). Push any release tab/clip and disconnect it. Note its orientation. Push it safely out of the way.
    • Fuel Feed Line: This is the high-pressure line going to the engine (often slightly larger diameter). Use the appropriate size fuel line disconnect tool. Slip the tool firmly over the line and push it completely into the fitting towards the tank assembly. Hold it there securely. Firmly pull the fuel line away from the module connector. You should feel the internal clips release. Fuel may drip; have a rag ready.
    • Fuel Return Line (if applicable - not all models/year combos have both): Similar procedure using the correct tool size. Push tool in, pull line off.
    • Vapor Hose(s): Locate the smaller vapor hose(s) attached to plastic nipples on the module lock ring or top plate. Squeeze the hose clamp (or remove the clip) and carefully slide the hose off. Note their positions.
  5. Disconnect Tank Straps: Locate the two large metal straps encircling the tank front and rear, secured by large bolts or nuts through the car's frame. Support the tank from below securely using your floor jack and a large piece of wood. Spray stubborn strap bolts/nuts with penetrating oil and let soak. Using the appropriate wrench/socket (often large - 24mm/15/16" or bigger), carefully loosen and remove the strap bolts. Keep one hand supporting the strap as the last bolt comes out. Remove the straps completely. Lower the tank slowly a few inches with the jack to get access to the top plate. Ensure the tank remains supported at all times.
  6. Disconnect Fill Neck: Access the fuel filler tube near the rear quarter panel. There should be a flexible hose clamped between the rigid filler neck coming from the gas cap and the tank inlet. Loosen the hose clamp and carefully twist/pull the flexible hose off the tank inlet. Fuel vapor may escape - work quickly.
  7. Disconnect Evap Canister Line (if accessible/required): Locate the charcoal vapor canister (usually near the rear). There will be a vapor line running to the tank top. Note how it's attached (clip/push fitting? clamp?) and disconnect it. You might need to lower the tank further to access this.
  8. Lower the Tank Fully: With all lines disconnected, straps removed, and filler neck detached, slowly and steadily lower the jack holding the tank. Keep it straight and level. Lower it enough so you can clearly see and work on the top of the tank assembly. Have blocks or stands ready to place the tank down securely, or lower it all the way to the ground if safe and possible.
  9. Remove the Lock Ring: Clean the area meticulously around the lock ring and top plate to prevent dirt from falling into the tank. Using a brass punch or large flat-blade screwdriver and a heavy hammer, firmly tap the lock ring counter-clockwise at the notches until it breaks loose. DO NOT strike the top plate or seal area. Continue rotating the ring counter-clockwise until it unthreads completely. Lift the ring off carefully. Note how the tabs are positioned relative to the tank.
  10. Remove the Fuel Pump Assembly: Grasp the module assembly firmly. It might be stuck by the large O-ring seal. Carefully wiggle and lift the assembly straight up and out of the tank. Keep it as level as possible to avoid bending the sender float arm. Once clear, immediately set it on a clean surface away from dirt. CRITICAL: Cover the tank opening immediately with a clean rag or piece of plastic to prevent debris falling in.

Step-by-Step Replacement Guide: Installing the New Module

  1. Prep the New Assembly: Remove the new pump module from its packaging. Compare it visually to the old one to ensure it's the correct part. Often the new strainer sock is packaged separately; install it firmly onto the pump inlet tube. Double-check that the large O-ring/gasket is correctly seated in its groove on the new module's top plate. Lightly lubricate this O-ring only with clean motor oil. DO NOT use silicone grease or anything petroleum-based near this seal unless it's specifically labeled safe for fuel contact. Clean motor oil helps it seal smoothly.
  2. CLEAN the Tank Seal Surface: Before installing, the metal surface on the tank where the O-ring seals must be spotless. Use clean rags and brake cleaner to thoroughly remove all traces of old sealant, gasket material, grime, and debris. Dirt here is the enemy of a good seal! Ensure it's completely dry.
  3. Install New Module into Tank: Uncover the tank opening. Carefully lower the new module assembly straight down into the tank. Align the float arm (ensure it's on the correct side for tank orientation) and the locating tabs/notches on the module top plate with the slots in the tank opening. Push it firmly and evenly down until the O-ring is seated correctly within the tank's sealing surface. The top plate should sit flush or slightly recessed.
  4. Install New Lock Ring: Place the new lock ring over the top plate. Align its tabs with the slots in the tank and the module top plate. Ensure the ring is correctly oriented (observe the slight angle or directionality - usually matching old position). Using the brass punch/screwdriver and hammer, firmly tap the ring clockwise until it is fully seated and stops rotating. It should feel tight against the stops. This ring provides the clamping force for the seal.
  5. Raise Tank Partially: Carefully raise the tank back up with the floor jack, aligning it roughly into position. Ensure no wires or hoses are pinched under the tank.
  6. Reconnect Hoses and Lines: Working at the top of the partially raised tank:
    • Electrical Connector: Firmly reconnect it. Listen for the click and ensure it's fully locked.
    • Fuel Feed Line: Verify the O-ring/seal is in place on the new module nipple. Push the line straight onto the nipple firmly until you feel/hear the clips fully engage inside. Give it a firm tug back to confirm it's locked. Repeat for Fuel Return Line if applicable.
    • Vapor Hose(s): Slide each vapor hose securely back onto its nipple and clamp firmly (or reinstall clips if required).
    • Evap Line: Reconnect if previously disconnected.
  7. Reconnect Fill Neck: Reconnect the flexible filler neck hose to the tank inlet pipe. Ensure it's pushed on completely and securely tightened with its hose clamp.
  8. Reattach Tank Straps: Position the straps back under the tank and over the frame points. Insert the bolts/nuts by hand to start, ensuring straps are seated correctly. Support the tank with the jack during this. Tighten the strap bolts/nuts evenly using a wrench/socket until the tank is snug against the body. Do NOT overtighten. You want the tank secure but not crushed. Refer to a torque spec if possible.
  9. Final Tank Raise: Check that all connections are secure and hoses/wires are clear. Raise the tank slowly the final inch or so until the straps are supporting it fully against the body. Tighten the strap bolts slightly more if needed for slight snugness, still avoiding overtightening.
  10. Install New Fuel Filter: While under the car, locate the external fuel filter (usually along the frame rail near the tank). Relieve pressure if the system was pressurized momentarily during checks. Follow the filter's direction arrow. Disconnect the lines using fuel line disconnect tools (usually similar size to tank lines). Replace the filter. Reconnect the lines securely - double-check the locking clips engage. Make sure flow direction is correct!
  11. Reconnect Battery: Reattach the negative battery terminal securely.

Start Up & Critical Leak Check

  • Turn the ignition key to "ON" (not start). You should clearly hear the new pump hum for 2-3 seconds. Listen near the tank.
  • Turn key to "OFF," then back to "ON" again. Listen again for the prime cycle. Do this 3-4 times to help prime the lines fully.
  • Inspect Leaks IMMEDIATELY: Before cranking, get under the car with a powerful flashlight.
    • Visually inspect ALL connection points at the top of the tank: Fuel feed line, return line (if any), vapor lines, the large O-ring seal perimeter of the lock ring.
    • Visually inspect the new fuel filter connections.
    • SNIFF Carefully: Strong gas odor near the tank area requires immediate shutdown! Identify the source.
    • Feel for leaks with a clean rag or glove (avoid direct contact with potentially pressurized fuel).
  • If NO leaks are detected: Start the engine. It might crank for a few extra seconds while lines prime completely. It should start and idle normally. Let it run for at least a minute. Get back under and perform the same thorough visual and sniff leak checks AGAIN. Pay close attention to all connections.
  • If you detect ANY leak: Turn the engine off IMMEDIATELY. Disconnect the NEGATIVE battery cable. Do NOT continue until the source of the leak is found and corrected. Even a small weep requires fixing.
  • Monitor the Gauge: Confirm the fuel level gauge on the dash starts registering correctly (might need to drive a bit to stabilize). It should move more smoothly than the potentially failing old sender.
  • Take a Test Drive: Drive the car gently at first, then gradually test acceleration under load (up a hill). Listen for unusual noises. Verify all previous symptoms (hesitation, power loss) are resolved.

Choosing the Right Part: Navigating the Market

The fuel pump module you choose significantly impacts longevity and performance:

  1. Complete Module is Highly Recommended: As stressed earlier, replacing just the pump motor often proves false economy. The sender unit is equally prone to failure (causing inaccurate fuel gauges). The strainer sock degrades. The lock ring and seal are critical sealing components designed for one-time use. Biting the bullet on the full assembly minimizes the risk of needing another costly tank drop within a short time.
  2. Brand Reputation Matters: Stick with known Tier 1 or Tier 2 suppliers with solid reputations in fuel systems.
    • Motorcraft: The Ford OEM part. Usually the highest price but ensures perfect compatibility and expected OE durability. Includes all necessary seals and lock ring.
    • Bosch/Delphi/Denso: Major OE suppliers globally. Excellent quality, reliability close to Motorcraft. Used by Ford and many others. Often include complete kits.
    • ACDelco (GM OEM brand, but sells for Ford too): Reliable Tier 1 quality. Includes complete kit.
    • Carter/Spectra Premium: Reputable Tier 2 brands. Good value, generally reliable for the application. Include kits. Ensure they are new, not "remanufactured".
    • Avoid Unknown or Super Cheap Brands: Rock-bottom priced pumps often use inferior motors, plastics, and seals. They may "work" initially but tend to have shorter lifespans and higher failure rates. Some are poorly remanufactured cores. "Lifetime warranties" sound good but mean little if you have to replace the pump twice as often and do the labor yourself each time.
  3. Warranty: Look for warranties of 1-3 years minimum. Lifetime warranties on reputable brands (like Spectra) are a plus but factor in brand quality first.
  4. Check Kit Completeness: Before purchasing (or accepting delivery), verify the listing/photos show the pump, sender, strainer, lock ring, large O-ring, and any installation hardware/seals. Call the supplier if unsure.
  5. Beware "Remanufactured": Unless explicitly sold as such by a very reputable brand known for high-quality remans (like Bosch, and even then inspect closely), avoid. Inconsistent quality control is a major risk with remans, especially from unknown vendors. New pumps use the latest materials and designs.
  6. Purchase Point: Choose retailers with good reputations for automotive parts and customer service (RockAuto, reputable local parts stores like NAPA/Carquest Advanced/O'Reilly/AutoZone, online dealers like TascaParts). Verify return policies in case of a defective part (rare, but happens).

When Professional Help is the Smart Choice (Beyond DIY)

While replacing a 98 Town Car fuel pump is achievable for a determined home mechanic with the right tools and safety commitment, situations exist where calling a professional mechanic is the wiser, safer choice:

  • Lack of Required Tools/Space: No safe jack stands, insufficient tools, or no suitable (well-ventilated) workspace.
  • Severe Rust: Rusted tank straps, bolts, or filler neck connections can snap during removal, creating dangerous situations or needing additional costly parts/replacement of the tank itself.
  • Stuck Lock Ring: Sometimes, despite effort and penetrating oil, the lock ring refuses to budge without damaging the top plate or tank. Pros have specialized tools and experience.
  • Significant Leaks or Unexpected Findings: Finding a severely damaged tank, major leaks elsewhere, or complex wiring issues when you open things up might be beyond the scope of the planned project.
  • Uncertainty about Diagnostics: If you weren't able to definitively confirm the pump was the problem before starting the replacement (especially pressure check), a mechanic can verify the issue efficiently with professional tools.
  • Time/Skill Constraints: The job, safely done well, takes several hours for an experienced DIYer, potentially longer for a first-timer. Lack of comfort working under a large vehicle, handling fuel, or troubleshooting reassembly issues are valid reasons to seek help.
  • Fuel Tank Damage Risk: If the tank itself is damaged during removal or installation, repair/replacement adds significant complexity and cost that a shop may handle more easily.

Preventive Steps: Extending the Life of Your New Fuel Pump

A new fuel pump should last many years. Help ensure it does:

  1. Don't Run on Fumes: Consistently running the tank to "E" strains the pump. The fuel cools and lubricates the pump motor. Running with less than 1/4 tank increases heat and wear. Fill up before it gets critically low. The Town Car holds about 22 gallons.
  2. Replace the Fuel Filter On Time: Follow the manufacturer's schedule rigorously (often every 30,000-50,000 miles). A clogged filter forces the pump to work harder, generates heat, and shortens its life.
  3. Use Quality Fuel: Choose reputable gas stations known for clean tanks. While occasional "top-tier" detergent gasoline might offer minor cleaning benefits, the primary goal is avoiding water contamination and sediment from poorly maintained station tanks, which can plug your strainer sock prematurely.
  4. Minimize Debris: When filling up, avoid letting excessive amounts of dust or debris enter the filler neck, though the fuel cap design helps prevent this. If the filler area is excessively dirty, wipe it before opening.

Conclusion: Restoring Confidence on the Road

Diagnosing and replacing a failing 1998 Lincoln Town Car fuel pump is a demanding but rewarding DIY repair for the well-prepared owner.
