94 TBI Is 14 PSI Fuel Presure to HIgh

[stano]

1994 C1500 5.7 with 700R4. Is the 14 PSI presure on the fuel line to high. I have a 1991 book and it say 9 to 13 PSI. So I am not sure about 1994.

Stock spec is 9-13, but some folks tweak them as high as 14 in search of a tad more performance.

14 PSI is perfect

The regulator takes care of any excess pressure, and sends it back to the tank.

that's correct. 9-13 psi is the factory range. i wouldn't think 14 would be a problem as long as everything is in good shape. my 94 held just over 12psi, pretty steadily the one time i checked. and my fuel system has never had any issues. did you do the "quarter mod" to bump the pressure up a little? i thought about trying that, but i am reluctant to screw around with the regulator, since it's working well. swapping for an adjustable might be nice, though.

thanks guys

as far as the regulator being tampered with or adjusted, I am not sure.

We checked it and read the 91 book and wanted more info.
