    So one my pet projects is to try to breathe life into an old 95 tacoma. It stills starts at least. I recently did a fuel pressure test, and it was high: 48psi, when the book says it should be 31-37. It didn't matter if the vacuum was on or off the regulator.

    Assuming i didn't miss a kink in the return line, then is a bad regulator the only thing that would do this? or can something else cause high fuel pressure? I applied my own vacuum to the regulator, and got it to drop 44psi, so it seems to work somewhat. And I'm not sure that where Toyota attaches the vacuum hose would really create a vacuum.

    Also, how badly would you think that a tacoma with this high of a fuel pressure would run? I'm thinking this is not my primary problem, but i could be wrong.

    Unfortunately I dont currently live where my taco is, but i try to get ideas on what to look at the next time i'm in town.
