What is the proper fuel pressure

**Cam99** · 02-26-2007, 08:45 PM

Finally got around to hooking up my Autometer fuel pressure gauge and was wondering what the proper pressure should be. It hovers around 29lbs at idle and goes up to 45+ when i rev it. Don't have insurance back on it yet so I don't know what it does under load. Seem normal?

Did you have the car tuned anywhere?

Sounds pretty ballpark to me, which gauge did you get, the one that mounts in the car? Or the underhood one?

Kauffman's. My car also has the Focus pump. This was on the motor tune not the n20 tune, didn't think to switch it to see if there is a difference.

It's the one that mounts in the car. I actually mounted the sensor in a block right before the Zex controller box because I figured that would give me a good indication of what my pressure is doing when the nitrous is activated ( wet kit)
