Does anybody monitor LPFP pressure when driving? The Ford specification in the Hard Start/No Start Guide is 3-8psi. I was watching mine today and when the truck was cold it would drop down to .5psi. The longer I drove, the better it got. By the time I was at the end of my hour drive, it was between 5.5 and 7.3psi (digital gauge).
Any input on this?
