10 Gallon Fuel Cell with Pump: The Ultimate Upgrade for Reliable High-Performance Fuel Delivery

If you are building a high-performance street car, a drift machine, or a dedicated race vehicle, upgrading to a 10 gallon fuel cell with pump is one of the most effective ways to ensure consistent fuel delivery under extreme conditions. A complete fuel cell kit, like those offered by EVIL ENERGY, combines a lightweight aluminum tank, a high-flow 300 LPH inline pump, AN fittings, and a fuel pressure regulator into one package. This setup eliminates fuel starvation during hard cornering, acceleration, and braking, and it is compatible with gasoline, E85, and other racing fuels. Below, we break down everything you need to know about choosing, installing, and maintaining a 10-gallon fuel cell with pump.

Why You Need a 10 Gallon Fuel Cell with Pump

A 10-gallon fuel cell with pump is not just a bigger gas tank; it is a complete fuel delivery system engineered for performance and safety. The anti-slosh foam inside the tank stabilizes fuel movement, preventing aeration and reducing the risk of flashback explosions. The external inline pump, typically rated at 300 LPH, provides enough flow for engines making over 600 horsepower, including LS swaps, turbocharged builds, and supercharged applications. With a built-in fuel level sender (0-90 ohms) and AN10 inlet/outlet ports, these kits are designed for easy integration into custom fuel systems.

Key Components of a Complete Kit

A typical 10-gallon fuel cell with pump kit includes several essential parts that work together to deliver reliable performance:

  1. Aluminum Fuel Cell Tank: The tank is usually made from 1060-H24 aerospace-grade aluminum, which is lightweight, corrosion-resistant, and TIG-welded for strength. The 10-gallon size measures about 16 inches long, 16 inches wide, and 9 inches high, making it suitable for many vehicle layouts. It includes anti-slosh foam and a flush-mount cap.

  2. External Inline Fuel Pump: The 300 LPH pump is a 12V electric unit that delivers high flow at pressures up to 75 PSI. This pump is mounted outside the tank, making it easy to service and replace.

  3. AN8 Braided Fuel Lines and Fittings: The kit includes 20 feet of AN8 CPE black braided hose, along with swivel fittings (straight, 45°, 90°, and 180°), Y-blocks, and bulkhead connectors. These components ensure leak-free connections and allow for flexible routing.

  4. Fuel Pressure Regulator: An adjustable regulator (20-120 PSI range) lets you fine-tune fuel pressure to match your engine's requirements.

  5. Dual Fuel Filters: A 10-micron and a 100-micron inline filter protect the pump and injectors from debris.

Installation Tips for a 10 Gallon Fuel Cell with Pump

Installing a 10-gallon fuel cell with pump is a straightforward project if you have basic mechanical skills, but attention to detail is critical for safety and performance.

Mounting the Tank: Use the integrated mounting tabs to bolt the tank securely to a flat surface. The tank should be positioned away from exhaust heat and potential impact zones. Ensure the mounting surface can support the weight of a full tank (about 60-70 pounds).

Wiring the Pump: Run a dedicated power wire from the battery through a relay and fuse. Connect the pump's positive wire to the relay output, and use a switched 12-volt source (like the ignition or fuel pump prime circuit) to trigger the relay. Ground the pump to a clean chassis point.

Connecting the Hoses: Use the included AN fittings to connect the pump to the tank outlet, the regulator, and the engine fuel rail. Double-check all connections for tightness before adding fuel. After assembly, briefly turn on the pump to pressurize the system and inspect for leaks.

Common Problems and How to Avoid Them

Even with a high-quality 10-gallon fuel cell with pump, issues can arise if the system is not set up correctly.

  • Pump runs but no fuel pressure: This usually means the pump is not submerged or the filter is clogged. Ensure the pump inlet is located at the lowest point of the tank, and inspect the inline filter for debris.
  • Pump is noisy: A loud whining sound often indicates cavitation. The pump is sucking air because the fuel level is too low. Keep at least a quarter tank of fuel during hard driving.
  • Pump fails prematurely: Heat is the main culprit. Fuel acts as a coolant for the pump. Always maintain a sufficient fuel level, and check that your voltage is stable (12-13.5V).

Maintenance for Long Life

To keep your 10-gallon fuel cell with pump performing reliably for years, follow these simple maintenance steps:

  • Replace the fuel filter annually: The 10-micron and 100-micron filters should be changed every 10,000 miles or at the start of each racing season.
  • Inspect the foam: The anti-slosh foam inside the tank can degrade over time, especially with ethanol blends. Replace it every 3-5 years for pump gas, or every 1-2 years if you use E85.
  • Check wiring and connections: Vibration can loosen electrical connections. Inspect the pump's power and ground wires every few months for corrosion or damage.
