So I think my fuel pressure will be pretty high, how do I turn it down, or can I?

Is it bad to have high fuel pressure?

To check it for sure you ned a fuel pressure gauge of course and the only way to "turn" it down is to get an adjustable fuel pressure regulator in place of the stock one. Now if the pressure is insanely high and all of your fuel components are stock, then there's a restriction somewhere. The sotck fuel pressure reg. can also be sticking.

well, I know it'll be high because it was 40 psi w/ vacuum on. so it'll be what like, 43 oe 44 w/ it off, when you guys said it should be like 38.

Well, since that's not out insanely high, then I'd say the FPR is at fault...get an adjustable one...
