Fuel pressure ???

I want to get a fuel pressure gauge next. How much fuel pressure do these trucks have? Is a 30 psi gauge enough?

15 PSI is the max and then the front seal of the IP can be pushed out.

If your going to monitor a pressure that will never do anything but go down, it's not a bad idea to use a gauge with a max reading near that pressure. Then you're using the needle's full sweep.
