fuel pump wont pump
I just put a new tank and fuel pump assembly in my 01 express 3500 and now the pump isn't pumping at all. I can hear it cycling in the tank when I turn the key but no fuel to the rail. If I hold the test port open I can get air out and after a bunch of times a little fuel dribbles out. Anybody know what would cause that or do you think the new pump is just junk? Is there something I needed to do to bleed it or prime it could something not be on right? I also just changed the filter. seems like it would be hard to screw that up but?

Re: fuel pump wont pump
When I replaced mine I had to remove the return line at the intake and cycle the key.

Re: fuel pump wont pump
Figured it out. Not sure if the pump didn't extend all the way or if there's just that much space at the bottom but put another 6 gallons in and it picked it up. Already had almost 10 in so didn't think that was the issue but she's running fine and that fixed the stumbling problem too.
