Re: FP and hot motor
If by FP you mean Fuel Pressure and it goes up when the truck gets hot, it can only mean your fuel pressure regulator is having some problems. It is built with springs against a diaphragm. When the heat is too much, one or more of the springs can't take it and softens up. This caused fluxation in fuel pressure.
My $.02 worth.
