How do you know if a pressure regulator is bad and you don't have the $100 pressure gauge to test the pressure at the schrader valve? I have gas squirting out of the valve, but I dunno if it's enough, I just changed the fuel pump because the old one crapped out and a new filter, new plugs, wires, and a cap and just because I wasnt sure I took the airbox off to make sure it had plenty of air and it sucks really good at the MAF. I pulled a plug off and it has a faint smell of gas from trying to start it, but nothing too extreme.
