Hey guys,

Quick question. I just measured my fuel pressure with a very accurate gauge on the fuel rail. I'm suspicious of my FPR.

When I turn the key (without starting the car, I get 45psi of fuel pressure. When I START the car, and let it run for about 10 seconds, the fuel pressure goes to about 37 PSI.

Is this an acceptable range?


Thanks!

does it stay there as the revs rise? You might find that at idle the voltage output is lower so the motor doesn't get all the juice it needs for max output. Just a thought

That is identical to how my Formula reads, I've been told that is correct.

You are right on target. 35 to 40 is the accepted range.
