It is possible that it will make a difference.
With low fuel pressure it is not getting as much in there when the injector opens.
Because obviously more fuel will flow at 40psi as opposed to 30 psi given the same opening size and duration.
I am not sure how to run the fuel pressure gauge either, I have had that exact same problem.
I think that is what the pressure regulator is supposed to do.
At idle you will have good vaccum, so pressure is reduced, at full open throttle you should have little or no vacuum, so pressure goes up.
If it didn't run better, you can still have an issue with it not moving enough fuel, but I still dont really think that is the end all solution.
Actually, Audra may have an extra pump laying around if you wanted to try it out. I know we have removed a couple and went to single pump systems.
