Keep in mind that an underhood gauge will be of limited use. It will not diagnose a bad pump as you could also have a problem with a cracked or worn seat on the Fuel Bowl Relief valve.
Even with good fuel pressure at an idle while sitting in your driveway, it could be totally different when pulling a trailer up a grade.
An in cab electronic fuel gauge is the only way you will be able to determine if you fuel delivery system is performing properly under various load conditions.

100% correct... Its a good cheap starting test but will not tell you everything!
I can drop my fuel pressure from 65 to 20psi on a WOT run right now with a factory pump that is slowly failing...

I have a FASS pump. Just got 160/80's installed. was told to set pressure at 65psi.
Fass pump only goes to 55psi, I called fass they said to shim the return line to achieve 70psi pump return then set the fuel supply regulator to 65. problems I have been having are lopey idle
lots of black smoke and high egts'
do you think this could be the culprit?
