So my pressures are 16-17 idle, 13-14 wot, works great while im on the road but when the truck sits it loses all fuel pressure.every time i before i start it, the fp gauge usually reads 0, 1, or 2 but it starts fine and the fp jumps right back up. bumping the key will get 17 psi for those 25 seconds, then it'll drop back to 0. should i be checking something out or am i worrying over nothin

Once the pump is off your pressure bleeds back to 0 pretty quickly. Nothing to worry about unless it happens while the pump is running.
