Fuel Cell Assembly 22 Gallon FIA FT3.5

The 22 Gallon FIA FT3.5 Fuel Cell Assembly from ATL Fuel Cells is purpose-built for serious motorsports competitors and high-performance vehicle builders who demand reliability under extreme conditions. This FIA-compliant fuel cell serves racers, autocross enthusiasts, and custom fabricators who require fuel containment systems that meet sanctioning body safety standards while providing consistent fuel delivery for turbocharged and naturally aspirated engines alike. Whether you're constructing a dedicated track car, circuit racer, or off-road competition vehicle, this fuel cell assembly eliminates the compromises of stock fuel tanks and delivers the durability professional racing demands.

ATL Fuel Cells engineered the FT3.5 design with robust internal baffling and compartmentalization that minimizes fuel sloshing during hard acceleration, braking, and cornering—critical for maintaining fuel pressure stability and preventing carb starvation or EFI system fluctuations. The 22-gallon capacity provides extended range for endurance events while the FIA certification ensures the assembly meets crash safety, flammability, and structural integrity standards required by most sanctioning bodies. At 47.6 pounds, the complete assembly balances adequate fuel volume against weight-conscious vehicle geometry, and the compact 22 x 16 x 37-inch profile fits diverse chassis configurations from tube-frame racers to mid-engine platforms. The steel or aluminum construction (depending on configuration) resists vibration-induced fatigue and fuel permeation, with integrated mounting provisions and outlet/return line bosses reducing custom fabrication time.

Mechanics, fabricators, and series racers benefit most from this bolt-in-ready fuel cell when retrofitting aging race cars, converting street vehicles to track duty, or building competition platforms from scratch. The assembly suits both carbureted and fuel-injected engine combinations, though fuel-injected applications benefit from the integrated return-line topology that maintains consistent rail pressure across throttle transitions. Installation requires basic mechanical skill—secure the assembly within your chassis using the engineered mounting points, route fuel supply and return lines to your engine bay with appropriate AN fittings and containment, and verify all hose connections for leaks before first run. Compatibility spans most single-seaters, sports cars, muscle cars, and fabricated competition vehicles; consult your car's wiring schematic and fuel system design before ordering to confirm outlet/return port orientation and hose sizing match your planned induction system.
