Does this happen to anyone else? I shut my truck off, hop out and shut the door and the pump primes (like when you first start it, for just a sec or two). It doesn't do it every time, maybe once a day, if that. It just started doing this when my battery crapped out on me. I have a new battery and it's still doing it. Has this happened to anyone else? What might cause this? Also the truck runs great, I'm just concerned about the phantom fuel pump primer.
