how can you tell if you have had this "dealer conversion"

 

The lift pump is MIA or is sitting there basically disconnected. There shouldn't even be any lines going or coming from it. They made a straight run for the VP from the tank on my setup. Why they'd do the pump in the tank mod and then leave the old one still in the bracket is kind of a head scratcher. But if it is still there it's probably not functional.
Anyways, it looks like you're in the same boat as myself and you have two choices.
Drop the tank, install the draw straw kit, yank the internal pump, reinstall and all of that while going with the FASS setup. That should run about $500 at the cheapest. Labor extra.
Or you could just add a Holley Blue electric fuel pump inline, between the (pump in the) tank and the VP and leave what's working alone, no tank dropping needed!!! That will boost fuel pressure to where it should be, with a lot less work.
Choices, choices.....

 

Hey can anyone tell me the specific part number for a stock cummins campaign pump?

 

I just replaced my vp44 and lift pump at a local shop that knows what they are doing. I've been dealing with them for 30 plus years. It came to $2050.00.

 

YIKES!! God, THERE'S STICKER SHOCK!!!!! Congrats on the new pump but too bad you had to pay for it. I'd be reaching for the plastic if that happened here, KNOCK ON WOOD....

 

Quick question for someone out there. If I have a pressure gauge attached to the test port in the back of the fuel filter, should it show pressure when I turn the key on (not started)?

 

No, only if you bump the starter, then it should run for 30 seconds and show around 14 psi on the gauge.

 

Thanks for the reply. I forgot I had to bump the starter.
