I have an 01 dually that just got a new vp44 and then started to sputter and die about 1 month and half after the vp. It shouldnt be the vp. I have always had to rebleed and then it will start. I then started thinking my fass pump was bad since i had a gauge it would start to drop pressure and then the truck dies. I buy a new fass. Same problem. I then go and swap fuel and transmission relay and same thing. The only other problem i can think pf is a high pickup tube missing the fuel since i am at a little below an 1/8 tank. Thanks

 

Have you tried adding any more fuel? Otherwise if you have to keep re-bleeding the fuel lines it would seem to me like you have a leak in the fuel system somewhere.

 

I don't let my truck get below 1/4 tank, mine would suck air and die if I was any lower than that and I would have to crack the injector lines and turn it over. Its actually pretty common, I haven't had a problem in over 2 years keeping it above 1/4 tank...
