Default People with fuel pressure gauge

Just curious on what your fuel pressure is during idling, normal driving and at WOT (on the motor, and on the gas if available). Mine is usually flunctuates between 59 to 63PSI, which I guess is pretty normal. :D

Thanks

Yes, that sounds pretty normal to me. 63psi actually sounds a tad high, but should be fine.

Should be 58-59psi at idle, and when you got WOT it'll usually drop to 55'ish or so by redline.

I think that is high...I backed mine down to 48 and have noticed a difference. GM sets this to high from the factory and the LS1 burns to rich.

My fuel pressure sits from 45-48 at idle.

Never looked at it @ WOT.:D

We have to factor in the pressure sending unit's accuracy, which is probably about +/- few PSI's.
