We installed a powerdyne supercharger un a 4.2L V-6, we have a problem with the gasoline. When it past of 5psi it's going empty, I have to change the injector but, we don't know the #? of the original injectors. Can any one installed a Supercharcher on a V-6 4.2L and change the injectors, or know the original #? of the injector.
