Weld-In Fuel Injector Bung - Pico

This weld-on mounting bung is designed for Pico-size injectors and other compact injectors with a 33.6 mm O-ring-to-O-ring spacing and 14 mm O-rings. It features a top fitting with a 1/8″ NPT pipe thread, making it easy to attach hard lines or AN fittings.

The bung can be welded or brazed to aluminum, or epoxied in place with proper sealing. It’s ideal for custom fuel delivery setups, such as adding staged injectors to a charge pipe or retrofitting injectors into a carbureted intake manifold where a traditional fuel rail is not feasible.
