    There has to be an easier way or ridding the air out of the system right? like when my truck has run out of diesel a few times its because the gauge barely works. 1/4 tank on that means damn near empty. the bobcat we have at work when it runs out you fill it back up, crack open a vavle deal and pump a rubber ball to force the air out and diesel in. then it fires right up...sometimes im workin on 2-3 hours to get mine started with the battery so weak and all. jumpin thpse dual batteries takes forever! any help would be sweet! /forums/images/graemlins/truck.gif

    Crack open a couple of the injector lines while cranking to purge out the air. Once fuel starts coming out tighten it up.

    When I was doing the injector pump and fuel tank swap, I got a small electric pump from checker and temporarily hooked it up, then I pressurized the tank with about 2psi. That way you dont have to run the starter to get the fuel system bled. It started right up everytime. Seems like a pain but, once you do it and see how easy it is you wont do it any other way. /forums/images/graemlins/truck.gif
