Electric fuel pump - need direction

[Tommy]

Jim,
I have no experience with that particular pump, so I can't comment on it in particular. But as you are making significant changes to your fuel delivery system, I will offer a few comments.

If all you do is cruise and seldom run wide open for extended periods, most electric fuel pumps are adequate. However, if you plan to use your car on the track, I suggest you run a pump with a separate downstream pressure regulator with a return line back to the tank. The reason is that fuel pumps with internal pressure regulators (like the one you are considering) control their output pressure by shunting excess fuel from the output side of the pump back to the input side. When the pump gets hot from heavy use, the fuel that is circulating through the pressure regulator system can get hot enough to boil and cause vapor lock. Having a separate pressure regulator downstream allows the pump to push the fuel through only once, so it doesn't get hot enough to boil. The excess fuel sensed by the pressure regulator is routed back to the fuel tank via the return line.
