Normal fuel pressure range?

Since I finally got my Glowshift fuel pressure working ... What is a good base fuel pressure on these 7.3s?

My gauge is showing 69.

You're actually a bit high it should be around 60 tops. But i don't think it will hurt anything. By the way did you use the upper plug or the lower one? The lower is after filter pressure.

I used the lower one. Will that cause the higher range?

Someone could have modified the spring. Regulator is on the top RH side of the fuel bowl. It has 2 torx head screws holding it on. But if you're going to tear into it I highly recommend resealing the whole housing. Dieselorings.com sells a kit for pretty cheap. 20$ or so. Idk if someone else will chime in but i've heard glowshifts FP sender is inaccurate. Again i wouldn't worry about it. Its not off the charts too high.

No... He is not.

He is spot on where it should be.

Normal pressure is between 65-72psi. Anything above 60psi is fine.

60psi tops... Where to people come up with this?

Where should you take the pressure from? The upper or lower plug?

I would prefer post filter pressure readings, so I'd use the lower port.

It really doesnt matter that much, upper or lower... Just having a baseline is the most important thing.
