Aluminum Weld Bung -12AN Female

The Vibrant Performance Aluminum Weld Bung -12AN Female (VIB11164) is a crucial component for custom engine builds and high-performance fuel line routing. This weld bung acts as a threaded port termination point, enabling the sealing off of unused fuel rail bungs or the creation of custom fuel delivery points in fabricated intake manifolds and fuel rails. It is particularly useful for those upgrading carbureted engines to EFI or building race-spec fuel systems.

Constructed from lightweight aluminum alloy, the Vibrant Performance weld bung is designed for direct welding into fuel rail bungs or manifold ports, ensuring a secure fit without deformation. The -12AN female thread specification allows compatibility with standard -12AN fuel line fittings, hose adapters, and pressure test ports commonly used in modern fuel systems. This component is engineered to maintain full pressure integrity in various fuel applications.

Ideal for engine builders, fuel system integrators, and fabricators, this weld bung supports custom EFI conversions and competition fuel systems. Its compact design allows for installation in tight engine bay environments, making it a preferred choice among professional mechanics and automotive enthusiasts alike.
