This is a weld-on mounting bung for Pico sized injectors and other tiny injectors with a 33.6 mm O-ring to O-ring distance and 14 mm O-rings, with a top fitting with a 1/4″ NPT pipe thread for attaching hard line or AN fittings. It can be welded or brazed to aluminum, or held on with epoxy if sealed correctly. These could be used to add additional injectors to a charge pipe for staged injection, or to add injectors to a carbureted manifold if you do not want to use a conventional fuel rail design.
New revision is about 1/4″ shorter for more mounting room and puts the injector closer to the manifold.
Made in the USA from billet aluminum.
