Aluminum Bolt In Bung Small

The Aluminum Bolt In Bung Small from Allstar Performance is a precision-engineered fitting designed for custom fuel system installations, coolant lines, and vacuum-operated components in high-performance automotive builds. Whether you're fabricating a fuel cell setup, integrating aftermarket cooling solutions, or installing auxiliary systems, this aluminum bung serves as a reliable termination point where standard bungs don't fit. Built for fabricators and engine builders who demand clean, leak-free connections on tight budgets, the small-format bung is an essential component for any serious modification project.

Constructed from lightweight aluminum alloy, the Aluminum Bolt In Bung Small delivers corrosion resistance and durability without adding unnecessary weight to your fuel or coolant system. The bolt-in design allows direct mounting to tank flanges, manifold ports, or custom fabricated panels, eliminating the need for welding and reducing installation complexity. Its compact dimensions (4.05 x 0.9 x 7.1 inches) make it ideal for space-constrained engine bays where larger fittings would interfere with headers, intake manifolds, or radiator hoses. The aluminum construction also provides excellent thermal conductivity, reducing heat transfer to fluids passing through nearby connections—a critical advantage in high-output turbocharged and supercharged applications.

This bung is ideal for engine builders, fuel system integrators, and custom fabricators working on street rods, race cars, and late-model performance conversions. Installation requires standard fasteners and basic hand tools; simply align the bung to your mounting surface and secure with bolts—no specialized equipment necessary. The small profile ensures compatibility with OEM and aftermarket fuel tanks, coolant reservoirs, and catch can systems. At just 0.19 lbs, the Aluminum Bolt In Bung Small adds minimal weight while providing a robust, reusable connection point that withstands repeated assembly and disassembly during development and maintenance cycles.
