Anyone have issues with their fass lift pump pumping fuel, mine is starting to , when you turn on the key you can here the pump get power to it but doesn't pump, I have went under the truck and kinda knock it around and then it would take off, do you think the motor is going out already very frustrated with lift pumps, I've already went through a air dog that failed and now seems the fass is failing
