There should be a fuel pressure port to the right of the fuel filter housing near the water drain valve facing the engine valley.

Viewed from the top of the fuel filter housing. Yep, it should be brass and with a hex head. You should see about 55 psi with a very good pump. I have seen them work with lower pressure but 55 psi is what is calls for.

Just remember that fuel pressure can vary on these trucks. The regulator is just a small spring, and over time the fuel pressure can drop even with a very good strong pump. Some folks shim the spring in order to bring the pressure back up.
