20 Gallon Fuel Cell with Fuel Pump: The Ultimate Guide to Choosing and Installing the Right Setup
If you are looking for a reliable and high-performance fuel system for your race car, off-road vehicle, or custom build, a 20 gallon fuel cell with fuel pump is one of the most practical and efficient solutions available today. This combination offers a large fuel capacity, integrated pump for consistent fuel delivery, and a space-saving design that simplifies installation. Whether you are building a street car, a drift machine, or a drag racer, a 20-gallon fuel cell with a built-in pump provides the fuel volume and pressure needed for high-horsepower engines while eliminating the hassle of separate pump mounting and plumbing. Below, we break down everything you need to know about these fuel cells, including key features, how to choose the right one, installation tips, and top recommendations.
What Is a 20 Gallon Fuel Cell with Fuel Pump?
A fuel cell is a specialized fuel tank designed for performance and safety, often used in racing and high-performance vehicles. A 20-gallon fuel cell holds approximately 75.7 liters of fuel, which is enough for extended driving sessions or long-distance races. When combined with an integrated fuel pump, the system becomes a complete, self-contained unit that delivers fuel directly to the engine. The pump is mounted inside the cell, which keeps it cool, quiet, and protected from external damage. Many aftermarket fuel cells come with a pre-installed pump, such as the Aeromotive 340 LPH pump or the A1000 pump, which are capable of supporting engines with up to 700+ horsepower for forced induction or 1000+ horsepower for naturally aspirated setups .
Why Choose a 20 Gallon Fuel Cell with Fuel Pump?
There are several reasons why a 20-gallon fuel cell with an integrated fuel pump is a popular choice among enthusiasts and professionals.
1. Simplified Installation
Traditional fuel systems require a separate fuel tank, fuel pump, filters, and mounting hardware. With a fuel cell that has a built-in pump, you eliminate the need for additional plumbing, brackets, and wiring. Simply strap the cell into your vehicle, connect the fuel line to the pump outlet, and attach the power wires. This saves time, space, and reduces the risk of leaks or installation errors .
2. Consistent Fuel Delivery
The integrated pump is designed to work with the cell’s internal baffling, which prevents fuel from sloshing away from the pump inlet during hard acceleration, braking, or cornering. This ensures a constant supply of fuel to the engine, which is critical for high-performance driving. Many cells, such as the Aeromotive Stealth series, feature an innovative baffle system that keeps the pump submerged at all times .
3. Noise Reduction and Cooling
Because the fuel pump is mounted inside the fuel cell, it is submerged in fuel, which dampens noise and helps cool the pump. This extends the pump’s life and reduces the risk of overheating, which is a common issue with externally mounted pumps .
4. Safety and Reliability
Fuel cells are typically constructed from aluminum or steel, offering better impact resistance and fire protection compared to plastic tanks. Many models include rollover valves, which prevent fuel spillage in the event of a crash. The built-in pre-pump filter also helps protect the pump from debris, ensuring long-term reliability .
Key Features to Look for in a 20 Gallon Fuel Cell with Fuel Pump
When shopping for a 20-gallon fuel cell with a fuel pump, consider the following features to ensure you get the best product for your needs.
1. Pump Type and Flow Rate
The fuel pump’s flow rate is measured in liters per hour (LPH) or gallons per hour (GPH). For most high-performance applications, a pump that delivers at least 340 LPH (about 90 GPH) is recommended. For example, the Aeromotive 340 LPH pump can support up to 700 horsepower for forced induction engines and 850 horsepower for naturally aspirated engines. The Aeromotive A1000 pump flows 380 LPH and supports even higher horsepower levels. For extreme builds, the Aeromotive Eliminator pump delivers 503 LPH and can handle over 1,900 horsepower .
2. Material and Construction
Most fuel cells are made from aluminum, which is lightweight, corrosion-resistant, and easy to weld. Look for TIG-welded construction for maximum strength and durability. Some cells are also powder-coated or come in a natural aluminum finish. The thickness of the aluminum is important; a minimum of 3mm is recommended for structural integrity .
3. Baffling and Foam
Internal baffling or foam helps prevent fuel slosh and keeps the pump inlet submerged. Some cells use a combination of both. Baffles are permanently welded inside the tank, while foam is a removable insert that also helps reduce the risk of explosion by filling the empty space in the tank. Many high-performance cells use baffling instead of foam for better flow .
4. Sending Unit and Fuel Level Monitoring
A fuel level sending unit is essential for monitoring your fuel level. Most cells come with a 0-90 ohm sender, which is compatible with most aftermarket gauges. This allows you to keep track of fuel consumption during a race or drive .
5. Outlet and Vent Fittings
The size and type of fittings are important for matching your fuel system. Common outlet sizes are -8 AN or -10 AN, while vent fittings are usually -8 AN. Look for rollover valves that automatically seal the vents in case of a crash to prevent fuel spillage .

How to Install a 20 Gallon Fuel Cell with Fuel Pump
Installing a fuel cell with an integrated pump is straightforward, but it requires careful attention to safety and proper connections.
Step 1: Choose the Mounting Location
The fuel cell should be mounted in a secure location, typically in the trunk or rear of the vehicle. Make sure the mounting surface is flat and strong enough to support the weight of the cell when full (about 160 pounds for 20 gallons of fuel). Use mounting straps or brackets that are rated for the weight .
Step 2: Secure the Fuel Cell
Place the fuel cell in the desired location and use the provided mounting tabs or straps to secure it. The cell should be firmly attached to the vehicle’s chassis to prevent movement during driving. Some cells come with a flush-mount lid assembly that makes installation easier .
Step 3: Connect the Fuel Lines
Attach the fuel outlet line from the pump to the engine’s fuel rail or carburetor. Use the appropriate AN fittings and ensure all connections are tight. The return line from the fuel pressure regulator should be connected to the return fitting on the cell. Make sure to use fuel-rated hoses and clamps .
Step 4: Connect the Electrical Wiring
The fuel pump requires a power source. Connect the positive wire to a switched 12-volt power source, such as the ignition switch or a relay. The negative wire should be grounded to the chassis. Use a fuse or circuit breaker rated for the pump’s amperage to protect the system .
Step 5: Vent the Fuel Cell
The fuel cell must be vented to prevent pressure buildup. Connect the vent lines to the rollover valves on the cell and route them to a safe location outside the vehicle. Some cells have dual vents for better airflow .
Step 6: Test the System
Before driving, fill the cell with fuel and check for any leaks. Turn on the ignition and listen for the pump to prime. Check the fuel pressure to ensure it is within the specifications for your engine. If everything is working correctly, you are ready to hit the road or track.
Maintenance Tips for Your 20 Gallon Fuel Cell with Fuel Pump
To keep your fuel cell and pump in top condition, follow these maintenance tips.
1. Regularly Inspect the Fuel Filter
Most fuel cells come with a pre-filter that should be checked and cleaned periodically. If your fuel cell has a 100-micron stainless steel filter, it can be cleaned with solvent or replaced if clogged. This helps protect the pump from debris .
2. Check for Leaks
Inspect all fuel line connections, fittings, and the cell itself for signs of leaks. Pay attention to the O-rings and seals, which can wear out over time. Replace any damaged components immediately to prevent fuel spills .
3. Keep the Fuel Cell Clean
Dirt and moisture can contaminate the fuel and cause damage to the pump. Always use clean fuel and avoid leaving the fuel cell open for extended periods. If the cell is used for racing, consider draining the fuel after each event to prevent stale fuel from clogging the system .
4. Monitor the Fuel Level Sender
If your fuel gauge starts to read incorrectly, the sending unit may be faulty. Most sending units are 0-90 ohm and can be replaced easily. Test the sender with a multimeter to ensure it is working correctly .
