Fill Plate Alum. w/Flap Valve -8an Fittings

The ATL FUEL CELLS Fill Plate Aluminum with Flap Valve and -8AN Fittings is a precision fuel system component engineered for high-performance and racing applications where reliable refueling and fuel containment are critical. Designed for custom fuel cell installations, this aluminum fill plate serves as the primary access point for fuel delivery while incorporating a flap valve mechanism that prevents fuel siphoning and maintains system integrity during vehicle operation, cornering, and impact scenarios. Whether you're building a dedicated track car, off-road competition rig, or street-legal performance vehicle, this component is essential for safe and efficient fuel system management.

Constructed from lightweight aluminum alloy, the fill plate minimizes weight while delivering the durability required in motorsports environments. The integrated flap valve operates passively, allowing fuel to enter the cell during refueling while automatically sealing to prevent fuel loss during acceleration, deceleration, and lateral g-forces—a critical safety feature in racing and rally applications. The -8AN fittings provide universal compatibility with standard braided fuel lines and quick-disconnect couplers, allowing seamless integration into both traditional and modern fuel system architectures. Compact dimensions (7.65 x 3.15 x 20.65 inches) enable flexible mounting options within engine bays and custom fuel cell installations, while the 2.42 lb weight keeps total vehicle mass low without compromising structural integrity or functionality.

This fill plate is ideal for fabricators, race teams, and serious enthusiasts upgrading from stock fuel systems or installing custom ATL fuel cells in competition vehicles. The -8AN fitting standard ensures compatibility with professional-grade fuel system components and aftermarket fuel pumps commonly found in turbocharged, supercharged, and naturally aspirated builds. Installation requires basic mechanical knowledge and welding or bolting capability depending on your fuel cell mounting method; consult your fuel cell manufacturer's guidelines for specific orientation and sealing requirements. Proper installation of the flap valve is essential—ensure the valve moves freely and seals completely to maintain system safety and prevent fuel spillage during extreme driving conditions.
