Your last video on post #13..............From your words on the video you start out with the engine running............13 plus vdc...........evidently the vacuum line is not connected to the FPR and the FPR is reading 50psi on your gauge.

Again, a stock car with the pump running and no vacuum to the FPR should read approx 37-39 psi and your reading 50 psi.

Then you apply pressure to the FPR and the gauge reads 10 psi higher i.e. 60psi. From what I've seen in the past on a stk car the pressure will read 37-39 psi with no vac to the FPR and if you apply pressure with a Mittyvac to the FPR the reading will go up to 50 psi. In fact no matter how much more pressure you apply the things never went more than 50 psi if memory is correct.

If it were me I'd borrow another fuel pressure gauge and see how things are. Seems many of your readings are approx 10 psi higher than what I've seen in the past. Gauge???????

Any idea of how much that setup cost? I'd be willing to look into it just to be sure I'm getting the correct pressure.

I'll test the voltage at the pump tomorrow. It has a new ground and new 12ga wire running from the Haltech fuse block
