4 Gallon Wedge Cell

The 4 Gallon Wedge Cell fuel cell is purpose-built for serious automotive enthusiasts and race teams seeking lightweight, high-performance fuel storage for modified vehicles. Whether you're building a track-focused street car, a competition-grade off-roader, or a custom hot rod, this wedge-design fuel cell maximizes usable space while fitting into tight installation areas where traditional rectangular tanks cannot. The compact wedge geometry allows builders to optimize weight distribution and interior packaging without sacrificing fuel capacity.

ATL Fuel Cells' 4 Gallon Wedge Cell is engineered with motorsport-grade construction to handle the demands of high-output engines, fuel injection systems, and performance fuel pumps. The wedge profile minimizes sloshing during aggressive cornering and braking, maintaining consistent fuel delivery under lateral and longitudinal g-forces—critical for vehicles experiencing sustained track duty. At 5.18 lbs when empty, this fuel cell delivers significant weight savings compared to OEM tanks, contributing to improved acceleration, handling balance, and fuel economy. The cell's compact footprint (13.45 x 11 x 20.65 inches) makes it ideal for custom fabrication projects, restorations, and competition vehicles where space constraints demand creative fuel system solutions.

This fuel cell benefits racers, vintage car restorers, and weekend warriors who demand reliability without unnecessary weight. Installation typically requires basic fabrication skills and compatibility with aftermarket fuel pump assemblies and surge tanks. The wedge design pairs exceptionally well with rear-seat delete builds, mid-engine conversions, and tight trunk spaces common in sports cars and custom builds. Verify mounting provisions and fuel system plumbing requirements during planning to ensure seamless integration with your vehicle's fuel pump, regulator, and feed lines. The 4 Gallon capacity suits autocross, road course, and street applications where frequent fill-ups are acceptable, making it especially popular among track enthusiasts optimizing weight and center of gravity.
