Fuel Cap Top Assembly

The JOES Racing Products Fuel Cap Top Assembly (Part No. 13277) is a precision-engineered screw-on filler cap designed for high-performance racing and marine applications. Constructed from aluminum and finished in black anodized coating, this fuel cap assembly delivers the corrosion resistance and durability required in demanding saltwater and freshwater environments. The compact 3 x 2.5 x 4-inch design integrates seamlessly into tight engine compartments while maintaining secure, leak-free fuel system integrity during operation.

Black anodized aluminum provides superior protection against oxidation and salt-air corrosion—critical for offshore and coastal boating where standard steel fasteners deteriorate rapidly. The screw-on design ensures a positive mechanical lock that resists vibration-induced loosening during high-RPM engine operation or rough water conditions. At just 0.2 pounds, this assembly adds minimal weight to your fuel system while maintaining the structural integrity necessary for reliable performance across extended cruising and racing applications.

This cap assembly suits both weekend boaters seeking dependable fuel system components and serious offshore anglers or performance racers who demand components engineered for demanding conditions. Racing fuel systems and high-output marine engines require fuel caps that resist pressure spikes, maintain airtight seals, and withstand constant thermal cycling. The JOES Racing Products design addresses all three requirements, making it an ideal direct replacement for damaged, worn, or corroded factory caps on compatible racing and marine platforms.

JOES Racing Products has built its reputation on precision fuel system components and accessories used in circle track racing, drag racing, and marine engine applications. This Fuel Cap Top Assembly reflects that heritage—compact, corrosion-resistant, and engineered for repeated high-stress cycling. Whether you're refreshing aging fuel system components or upgrading original equipment, this aluminum cap delivers the performance consistency that serious boaters and racers expect.
