upgrade lift pump?
upgrade lift pump?
Im driving a 91 turbo cummins d250.
Im converting it over to run on waste vegetable oil and want to know if the stock diaphragm pump will work or if I should upgrade to a 94-98.5 piston type lift pump. Also consider that I have to put the filters on the suction side of the LP.
Also is there any special modifications that need to be done in order to do this upgrade and can I put the filters on the suction side of the LP.
