Re: Cummins conversion questions

My 95 12valve P pump ran like a scalded dog with is factory mechanical lift pump. If i was doing the swap to keep it simple i would run the mechanical lift pump on the engine and make sure to remove the in-tank sock or put 6.2 sending uninits in your tanks.

I am assuming your running a 12 valve 5.9 with a p7100 pump. Are you running different turbo? Turbos? Auto or manual trans?

Lots of factors could change what fuel pump would be ideal.
