[QUOTE=jkade;4419488]you can put a vortec pump in the sending unit if you wish. I have a 96 vortec pump on a 91 sending unit running a cammed LQ9.... runs great.

now when you say you put in a 96' vortec pump is that the one that was meant for the suburban/trucks? For some reason I thought that they were also TBI. But if your running an LQ9 then it must be providing enough pressure.

I know this forum is for LSX swaps but I'm actually installing an LT1/4L60E from a 95' camaro. Does anybody know what kind of fuel pressure this motor requires versus say a TPI motor or an LSX motor. I also know that the fuel system is supposed to have a return line and there is a fuel pressure regulator on the fuel rail. What I'm scratching my head about is can I send as much fuel to the regulator as I want and will it automatically regulate it down to the factory settting? I just don't want to put on a pump and then all of a sudden have way more psi at the injectors then what was intended from the factory.
