What is tha stock fuel pressure?

[cjman15]

Wanna put in a regulator and guage here soon and I was just curious to what tha stock pressure was... I don't know what it is... 30psi?

i think its actually around 40psi, give or take a few psi

OK cool, because I wanted to get those things and see if I can take care of an overfueling issue with my car, thanks

39-40 psi is about normal

Yep 40 PSI is the correct pressure

38-39 is spec with the vac line off and capped. with the vac line attached, at warm idle, pressure should be ~3-34 PSI.

the computer will adapt for pressure variances to get back to stoich - it is hard to run rich for very long with pressure set near stock (with stock injectors).

good luck.
