Fuel Cell Cap and Bung RCI/JAZ 12-Bolt Black

The Fuel Cell Cap and Bung RCI/JAZ 12-Bolt Black is a precision fuel cell filler cap assembly engineered for high-performance racing, off-road, and tactical vehicle platforms that demand reliability under extreme conditions. Designed for RCI and JAZ fuel cell systems, this screw-in cap assembly serves operators, fabricators, and motorsports professionals who require a secure, leak-free fuel containment solution. The 12-bolt configuration ensures maximum sealing integrity during acceleration, deceleration, and rough terrain operations where fuel slosh and spillage create safety and performance risks.

Constructed from aluminum and finished in black anodizing, the Fuel Cell Cap and Bung RCI/JAZ 12-Bolt Black delivers corrosion resistance and durability in harsh environments. The anodized surface protects against fuel degradation, UV exposure, and chemical contact while maintaining a low-profile, lightweight design at 1.42 lbs. The screw-in mechanism provides tool-free installation and removal, allowing quick access to fuel cells during maintenance or emergency situations. The 12-bolt pattern distributes clamping force evenly across the filler opening, preventing vibration-induced loosening and fuel vapor escape common in standard cap designs.

This assembly is ideal for users operating RCI or JAZ fuel cell systems in competitive racing, military vehicle conversions, armored platform builds, or expedition-grade off-road setups. The compact 8.1 x 1.35 x 11.1-inch footprint integrates seamlessly into engine bay configurations with minimal additional hardware. Installation is straightforward—simply align the 12-bolt pattern with your fuel cell opening and hand-tighten the screw-in cap to achieve a secure seal. Compatible exclusively with RCI/JAZ fuel cell platforms, this cap assembly ensures OEM-level fit and function for operators demanding zero-compromise fuel system integrity.
