Fuel Cell Cap and Bung JAZ 6-Bolt Red

The ALLSTAR PERFORMANCE Fuel Cell Cap and Bung JAZ 6-Bolt Red (ALL 40134) is a screw-in vented fuel filler cap assembly engineered specifically for JAZ 6-bolt fuel cell applications. This aluminum cap features red anodized finish and a raised cell mount design that provides secure sealing while maintaining fuel system venting integrity—critical for high-performance racing and off-road vehicles where fuel cell pressure management directly affects engine reliability and safety.

The 6-bolt JAZ fuel cell mount pattern is the industry-standard connection for modern racing fuel cells, and this ALLSTAR cap delivers proper fitment and clamping force to prevent fuel seepage during aggressive acceleration, braking, and cornering. The screw-in design allows quick installation and removal without special tools, while the vented architecture maintains correct fuel tank pressure equilibrium—essential when temperature changes or fuel consumption create pressure differential that can damage tank integrity or compromise fuel pump function. Aluminum construction with red anodizing offers corrosion resistance suitable for both street and competition environments.

This cap assembly is designed for racers, off-road competitors, and performance enthusiasts who run modern JAZ fuel cell systems—whether in circle-track racing, drag racing, off-road trucks, or high-performance street builds. Proper fuel cap selection is often overlooked but remains fundamental to fuel system integrity; a failed or undersized cap can create pressure leaks, fuel odor, and potential safety hazards during long runs or extreme driving conditions. The raised mount profile ensures adequate clearance when accessing or servicing the fuel cell, and the secure 6-bolt connection pattern guarantees compatibility across JAZ's complete fuel cell lineup.

ALLSTAR PERFORMANCE is recognized in the racing supply market for producing dependable fuel system components that meet the requirements of competitive and recreational motorsports. This fuel cell cap and bung represent straightforward engineering—no exotic materials or overcomplicated design—just proven vented-cap performance in the red finish that matches many race fuel cell configurations. Proper fitment, venting function, and corrosion resistance make this cap a direct replacement or upgrade choice for existing JAZ fuel cell installations.
