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.

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.

3rd gens need flow not pressure. If I ever do a pump on mine, I will do a fuelab. They are expensive, but reliable

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.

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.

Just because its low on pressure doesnt mean its also low on flow

With the  fuel line diameter, I really kinka think it would be an issue................................at least until someone can prove otherwise!!!
