I installed a cheap 15 psi Mr Gasket gauge today. I just removed the lower rubber hose between the filter and the CP3 lines and put a T in and ran the gauge inside the truck. I used 300 pound hose and just tie wrapped the gauge at the bottom of the dash on the left side as a temporary deal. I plan on buying an Isspro white face F/P gauge and the SRT10 A pillar. I know that it is not a great idea to do this without a isolator and thus the 300 pound hose. Any way just got home and with the truck off and just the lift pump running I see 7psi, running at idle I see about 5.5psi, and wot I see it drop to 3 to 3.5. Have not looked with the TST on in any setting yet. I am planning on doing Superduty's Walbro F/P deal. I just wanted to see what the pressure is stock. Hey Superduty is this the correct place to monitor Fuel pressure. It made sense to me. Thanks!
