Lift pump question

[danoscooter]

Can you use a hmvee lift pump on a cucv? The humvee on has an additional connection towards the top of it. I was gonna put the one off the old motor but it looks like they must of had issues around the seal because it was covered with lots of sealant. So now I'm wondering if I should just buy a new one.

Mine went bad last month and I also wondered the same thing. I could not make it work as the rod arm is different. NAPA has 2 versions available one heavy duty and one generic. Delphi DEM HFP909 for 46 bucks or Napa NFPM60281 for 20 bucks. I went with Delphi as it totally looks beefier when compared side by side and is a direct replacement. Make sure to crack your injectors and bleed system when done and use grease to hold arm in place, if arm moves, its a Beotch to get it placed perfectly again.

Wrong! As long as you disconnect the pink wire to the IP solenoid while you bleed the fuel filter, there is no need to deal with the high pressure side of the fuel system. Its SOP;standard operating procedure.

I did remove pink wire but when I replaced the mechanical lift pump I had to crack injectors.

That begs the next question, how old is your IP?

Thanks everyone! A new one it is.

I don't see how electric is an upgrade. The mechanical pump works fine in a stock setup.

Is that because the motor had not been running and you were cranking it over introducing air into the IP and lines?
