I just got my 01 cummins and I installedthe edge juice with attitude, the display is readin about 10 psi fuel pressure when at idle. It's supposed to be around 15. I got the service paperwork from the dealership and the transfer "lift" pump has been retrofitted to inside the tank. I called the dealership and the tech told me that it will read lower now because of that. I think the guy is full of crap and its gonna end up costin me a new injector pump! What do you guys then of all that?

 

What does it drop down to when you punch on it?

 

all the way to 1. i think it even dropped to zero once.

 

on an 01 you need to see no less than 4-6psi during WOT runs at redline. . .that pump will kill your VP44 if it pulls a vacuum.

 

thats what i figured but the guy from the dealership said it was fine. what do you think i should do? this is my first diesel by the way thats why i'm kinda lost. would a new lift pump fix it?

 

fass or walbro and you'll never have to worry about it again.

 

yeah i looked at the fass. unfortunately i'm in the army and i dont make enough of that green stuff to whip out six hundred bones like it aint nothin. would a walbro inline pump work? and if so how much lph does it need to pump?

 

If you put on a Walbro inline, you'll also need a pressure regulator. I learned the hard way and almost blew some of the fittings off of the fuel line. The PSI gauge I had only goes to 40, but I know it had more than that it the line because it was pegged!. Anyway, even with the regulator it is cheaper than the FASS. I used the 255lph model pump.

 

awesome. thanks man. thats the best info i've gotten yet
