The 12-Bolt Flush Mount Cap from JAZ is a precision-engineered closure component designed for fuel cell and tank systems in high-performance automotive applications. Whether you're building a circle-track racer, street rod, or dedicated race vehicle, this flush mount cap eliminates the risk of fuel spillage and contamination while maintaining a clean, integrated appearance on your fuel system. JAZ products are trusted by professional fabricators and engine builders who demand reliability under extreme conditions.

Engineered with a 12-bolt pattern, this cap provides secure, leak-proof sealing through precision threading and a flush-mount design that integrates seamlessly with modern fuel cell construction. The flush mount profile reduces aerodynamic drag and eliminates protruding hardware that could snag fuel lines or catch debris during high-speed operation.

This cap is ideal for fabricators and racers working with fuel cells in circle-track racing, road racing, drag racing, and street performance builds. Installation requires basic hand tools and alignment with the mating 12-bolt fuel cell opening; no special equipment is needed. JAZ's reputation for durability in motorsports applications means this component will withstand thermal cycling, vibration, and fuel exposure over thousands of miles of competitive or street driving.
