Fuel Cell Cap Red

The Allstar Performance Fuel Cell Cap Red (ALL 40135) is a screw-on aluminum fuel cell filler cap designed for racing fuel cells, fuel tanks, and specialty fuel systems. This red anodized cap provides a secure, sealed closure for fuel storage applications where reliable containment and corrosion resistance are essential. The screw-on design allows for quick access without requiring special tools, making it practical for both pit work and emergency refueling scenarios.

Constructed from aluminum and finished with red anodized coating, this fuel cell cap resists oxidation and corrosion from fuel exposure and environmental moisture. 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, reducing the risk of fuel evaporation or spillage during transport or high-speed operation. The compact design fits standard fuel cell filler neck openings used across racing platforms and custom fuel system builds.

This cap serves racers, fabricators, and off-road builders who need reliable fuel containment on custom or specialty fuel cells. It's commonly used in circle-track racing, drag racing, vintage restoration, and off-road competition where proper fuel system sealing is critical to both performance and safety. The bright red finish also provides easy visibility in engine bays and pit areas, reducing the chance of accidental fuel overflow during refueling operations.

Allstar Performance is a recognized supplier of racing fuel cell systems and fuel system components used throughout motorsports. This fuel cell filler cap is sold as a single unit and integrates with Allstar fuel cell kits and aftermarket fuel tank applications where standard OEM closures don't fit or aren't available.
