AN Weld Bung 20AN Male Aluminum

The AN Weld Bung 20AN Male Aluminum by Allstar Performance is a vital component for custom fuel system builds and high-performance engine modifications. This weld bung serves as a port or mounting point in aluminum fuel rails, tanks, and manifolds, ensuring a permanent, leak-free connection. It is designed for fabricating custom fuel delivery systems, installing fuel pressure sensors, or adding supply/return lines to modified engine bays.

Constructed from aluminum alloy, the AN Weld Bung features a 20AN thread size, which is the industry standard for high-flow fuel systems in racing and performance vehicles. The male threading design allows it to accept AN-spec hose fittings, adapters, and distribution blocks without the need for additional adapters, creating streamlined connections that minimize turbulence and pressure drop. The welding design ensures a permanent bond that can withstand vibration, thermal cycling, and pressure spikes typical in forced induction and nitrous oxide applications.

This bung is ideal for fabricators, engine builders, and enthusiasts who are designing fuel rails, constructing custom manifolds, or modifying aluminum fuel tanks for turbocharged, supercharged, or naturally aspirated performance engines. Installation requires welding into aluminum, making it a reliable choice for those looking to enhance their vehicle's fuel system.
