So last week, truck died while driving. Shot it down to my fuel pump, a Fuelab Prodigy 2 (41401-1). So I sent it back to fuelab under warranty (6 months old) and they updated all the parts inside to the newer style that is in the pumps currently. I got the pump back yesterday, put it in, changed the Baldwin filters, primed it With the outlet line off. Once I installed the outlet line, and turn the key to on, I ge 0-8 psi of fuel pressure. It fills up the filter bowl, but it seems to end there. I have a driven diesel reg return,I took the lines coming from the back of the heads off to let the air get pushed out, but nothing is coming out while pump is on. Once I shut the key off, a small amount of fuel will trickle out. I have the gauge right on the filter bowl and it isn't reading anything either. I'm stumped. What else is there to do?
