We now carry weld in injector bungs! These are designed to use a hose fitting instead of a fuel rail, so you don't have to worry about lining up all the injectors precisely with your fuel rail. You can use them for adding staged injection to the manifold or charge pipe, converting carbed manifolds to EFI, or making your own race manifolds. TIG them to your manifold or epoxy them on with JB-Weld.
These are made in the USA from billet aluminum. Price is $38.50 each.
