What to Look for in a 100 Gallon Fuel Tank with Pump

When choosing a 100-gallon fuel tank, consider these essential factors to ensure you get the best value and performance for your needs.

1. Material: Steel vs. Aluminum vs. Polyethylene

  • Steel (10-gauge or 14-gauge): Offers excellent strength and durability. LEE tanks use 10-gauge steel for resistance to deformation, bending, and impact. They are powder-coated for corrosion resistance . Steel tanks are heavier but extremely rugged.
  • Aluminum: Lighter than steel and naturally corrosion-resistant. JME Tanks and Boyd Welding use 5052 mill aluminum, which is both strong and lightweight. Ideal for reducing payload weight and avoiding rust in humid environments .
  • Polyethylene (Plastic): Lightest option, completely rust-resistant, and often more affordable. Enduraplas tanks are made from diesel-grade polyethylene for long life. They are perfect for seasonal use or environments where weight is critical .

2. Pump Type and Flow Rate

Pump selection is crucial for your fuel transfer speed and reliability.

  • Electric 12V DC pumps are the most common for portable tanks. Options range from 10GPM (Enduraplas) to 20GPM (LEE, JME) . For commercial operations, a 20GPM pump reduces refueling time significantly.
  • Hand pumps are available for grid-independent operation. The LEE DTL 100 offers a hand pump option that delivers 20 gallons per 100 strokes .
  • 115V AC pumps are available for shops with electrical outlets. LEE offers 15GPM and 20GPM versions .

Important Note: Do not mount a pump heavier than 30 lbs on standard tanks. This limit includes the pump and any accessories like filter kits or meters. For heavier pumps, use a Severe Series tank .

3. Tank Construction and Safety Features

  • Baffles: Internal baffles reduce fuel slosh during transport, improving stability. Most tanks, like the Boyd Welding and JME models, come with baffles .
  • Gauge: A fuel gauge is standard on most tanks, allowing you to monitor fuel level easily. LEE includes a gauge on every DTL 100 .
  • Vented Fuel Cap: A vented cap prevents pressure buildup. Some tanks, like the Boyd Welding, come with a separate rollover vent for extra safety .
  • Forklift Rails: Tanks like the LEE DTL 100 have integrated forklift rails for easy, single-operator transport .
  • Mounting Hardware: Look for bolt holes on flanges or hold-down brackets for secure installation. The JME tank comes with hold-down brackets .

4. DOT Certification

If you plan to transport gasoline or other flammable fuels, a DOT-approved tank is mandatory. The JME 100-gallon aluminum tank and the Transfer Flow system are both DOT-approved for gasoline, diesel, methanol, and kerosene . Steel tanks like the LEE DTL 100 are designed for class 3 combustible materials (diesel) but may not be DOT-rated for gasoline.

Why Upgrading Your Fuel Pump Matters: The KEMSO Advantage

While the tanks listed above come with capable pumps, upgrading to a high-performance aftermarket pump can dramatically improve reliability and flow rate, especially for heavy-duty or off-road applications. The KEMSO fuel pump is widely recognized as one of the best upgrades for both OEM replacement and high-performance builds.

KEMSO pumps deliver up to 340 liters per hour (LPH) at 45 psi, which is up to 20% more flow than many stock pumps . This extra capacity means your equipment gets fuel faster, reducing downtime. They are designed with a brushless motor that extends pump life to approximately 15,000 hours, compared to traditional brushed motors that may fail after 8,000 hours . For off-roaders and those operating in extreme conditions, KEMSO's patented swirl pot design maintains consistent fuel pressure even at 45-degree tilts, preventing fuel starvation on steep inclines or rough terrain .

What sets KEMSO apart:

  • High Performance: Compatible with both gasoline and E85, supporting up to 600 BHP for naturally aspirated, turbocharged, and supercharged applications .
  • OEM Replacement: Designed for easy drop-in installation, replacing Walbro and other stock pumps without modifications .
  • Lifetime Warranty: KEMSO offers a lifetime warranty and USA-based support, giving you peace of mind that your investment is protected .

Independent tests show that vehicles using KEMSO pumps averaged $120/year in fuel system repairs versus $310 for budget options, saving you money over time . Whether you're running a fleet of construction equipment or a modified off-road rig, a KEMSO pump ensures reliable fuel delivery where it matters most.

Installation Tips and Maintenance

Installing a 100-gallon fuel tank with pump is straightforward, but following best practices ensures safety and longevity.

  1. Secure the tank properly: Use the bolt holes on the flanges (for steel tanks) or mounting tabs (for aluminum tanks) to bolt the tank down. Never rely on tie-down straps alone for heavy tanks. The Boyd Welding tank recommends using brass fittings for installation .
  2. Wire the pump correctly: The pump typically needs a 12V DC power source with circuit breaker protection. Connect to a dedicated battery or auxiliary power system. The Enduraplas tank comes with alligator clips for easy connection .
  3. Maintain the pump: For electric pumps like the GPI series, inspect the filter regularly. KEMSO pumps feature a 50-micron filtration system to prevent clogging .
  4. Check the vent: Ensure the vented fuel cap is functioning to prevent pressure buildup inside the tank. If using ethanol fuels, check compatibility with seals.
  5. Winter storage: For polyethylene tanks, drain the fuel and store in a warm area if temperatures drop below freezing to prevent cracking.

Conclusion

A 100 gallon fuel tank with pump is an investment in productivity and convenience. Whether you choose a rugged 10-gauge steel tank from LEE, a lightweight aluminum model from JME or Boyd Welding, or a corrosion-proof polyethylene tank from Enduraplas, you'll have reliable on-site fuel storage. For those needing maximum flow and durability, upgrading to a KEMSO fuel pump ensures your equipment runs smoothly in any condition.

Make the smart choice today and bring the fuel station to your worksite.
