AN Weld Bung 8AN Male Aluminum

The AN Weld Bung 8AN Male Aluminum from ALLSTAR PERFORMANCE is a critical fitting for custom fuel system builds, turbo setups, and performance engine modifications. Designed for fabricators and mechanics who demand precision in high-flow fuel line routing, this weld bung provides a clean, permanent integration point for AN-sized fuel or coolant lines directly into custom tanks or manifolds. Whether you're building a dedicated race car fuel cell, upgrading to a larger capacity tank, or installing a secondary fuel system for boost applications, this aluminum weld bung eliminates the need for welded-on fittings and delivers professional results.

Manufactured from lightweight aluminum and featuring a male 8AN thread connection, this bung is engineered for TIG or MIG welding directly into aluminum or steel tank walls and custom fabricated components. The 8AN size (1/2-inch diameter) handles substantial fuel flow rates essential for high-horsepower engines, turbocharged applications, and fuel injection systems requiring reliable delivery without pressure loss. The aluminum construction reduces overall system weight—a priority in race and performance builds—while the precision-machined threads ensure leak-free connections with standard AN fittings and hose adapters. This design allows you to permanently mount the fitting before final assembly, simplifying plumbing layouts and improving aesthetics in engine bays.

Professional fabricators, drag racers, and street performance enthusiasts rely on ALLSTAR PERFORMANCE weld bungs to create custom fuel systems that maintain OEM-level reliability in modified vehicles. This fitting pairs seamlessly with 8AN hoses, inline filters, fuel pressure regulators, and distribution blocks commonly found in turbo setups, supercharged platforms, and dedicated race fuel cells. Proper welding technique and heat management are essential—TIG welding with aluminum filler rod is recommended for maximum strength and corrosion resistance. Installation requires basic metalworking skills and access to a welder, making this ideal for fabrication shops and experienced DIY builders working on serious performance or racing projects.
