I am about to start working on a Allis Chalmers tractor that has a gravity fed fuel system. It has a manuel primer pump that leaks and its just one more thing you have to do to before you can start it. I thought about putting a small lift pump in place of it. Will this work? It is a 130hp 400ci straight 6 with a rotary stanidine pump. How much pressure at the head of the pump should there be? Would the higher pressure (I'm thinking maybe 5psi tops) effect fuel usage?
