Fuel Cell Cap Red

The Allstar Performance Fuel Cell Cap Red (ALL 40135) is a screw-on aluminum fuel cell filler cap specifically designed for racing fuel cells. This cap is ideal for racers and fabricators who require reliable fuel containment in custom or specialty fuel cells. Its design ensures secure closure, making it practical for quick refueling scenarios.

Constructed from aluminum and finished with a red anodized coating, this fuel cell cap resists oxidation and corrosion from fuel exposure. The anodized surface provides a protective barrier that maintains structural integrity over repeated use cycles. The screw-on mechanism creates a positive seal when properly threaded, ensuring effective containment.

This cap is commonly used in circle-track racing, drag racing, and off-road competition where proper fuel system sealing is critical to performance and safety. Its bright red finish enhances visibility in engine bays and pit areas, helping to prevent accidental fuel overflow during refueling operations. The compact design fits standard fuel cell filler neck openings used across various racing platforms.
