My work truck (cummins ISX) has some kind of a lift pump but I really haven't had time to try and find it or get a part number... I say it has a lift pump, something it humming along the fuel line area when I turn on the key but not start the truck. I hear it but can't seem to locate the exact area (to many trucks running beside me), but it seems like it might be incorporated into the fuel filter housing...
I always thought it might be a good candidate for it's turned up little brother... but maybe fuel flow isn't enough...
