I have been through two pumps in 3 weeks, pressure drops ramdomly and the other leaked fuel. Now I just put the new on on and it drops to 10psi give or take when you start the truck, then it goes up to 18psi and works like a charm. Why does it drop pressure like that everytime the truck is started? It only happens once when started, other than that it holds psi good.
The truck primes and starts easily, it's after it is started and idled for like no more than a minute it drops psi to 10 or lower. Then the pump makes a noise and psi is back up to normal and fine from there on out.
