Posted September 14, 201410 yr whilest i was helping my dad (09 duramax owner) search for things for his truck we found. http://www.kennedydiesel.com/detail.cfm?ID=399 after searcing more i find LOTS of chevy guys love this lift pump... why not in the cummins world? enlighten me.
September 14, 201410 yr I know that the 3rd gen lift pumps are measured by volume/flow vs pressure but each of those pumps only giving 4 psi, makes me wonder. Is that enough pressure? I dont know what kind of pressure the cp3 needs to be seeing I guess.
September 14, 201410 yr 3rd gens need flow not pressure. If I ever do a pump on mine, I will do a fuelab. They are expensive, but reliable Edited September 14, 201410 yr by mopartechnician
September 14, 201410 yr At 4psi with (I'm guessing here) 3/8ths ID fuel line.....................I wonder if there would be enough pressure and flow for our trucks??? I'm almost positive that it wouldn't work on the 2nd gens.
September 14, 201410 yr Oh I know for sure it wouldnt work on the 2nd gens. We need at least 10 psi minimum. 15-20psi is ideal so I would need to put 4 of these in series it would appear. I just wasnt sure if they would flow enough for the 3rd gens either. 4 psi really isnt much at all.
