    I agree with Justin. The difference between the two pumps is volume capacity, not a pressure difference. It should start and run OK with the lower volume pump, but might stumble at WOT on a sustained high rpm run. Can you hear the pump running for sure? If so, it sounds like you've got something blocking flow. Maybe an old in-line filter? Have you put a pressure gauge on the fuel rail? That's one of the first things I'd add, just to know what pressure you're getting and eliminate the unknown. You can pick up a little 0-60psi liquid filled gauge for about $20.

    Enjoy the little things in life, and you may look back one day and realize that they were really the BIG things.
