Lift Pump Needed for '03 Dodge Cummins VO System

I have a 2003 Dodge Ram, 24V, 5.9L Cummins that was in January ’07 converted to run on straight vegetable oil (VO). The stock fuel system in the Cummins engine has the lift pump mounted on the fuel filter, i.e., NOT in the fuel tank. In my VO conversion system I have an MSD lift pump, (model # PN 2225, rated at 43 gph @ 40 psi, 5.4 amps [gasoline rating]) with a pressure regulator on the discharge of the MSD lift pump to regulate the VO pressure down to 6 to 9 psi, in the range that the injection pump likes to see. My MSD lift pump recently failed. I am in search of a new cost-effective lift pump to replace my failed MSD lift pump. I have to questions – (1) what would be a good readily available lift pump to use, make and model number, that is not too expensive, i.e., less than about $150 and (2) did I need to use a pressure regulator in the discharge of the MSD lift pump and will I need to use a pressure regulator in the discharge of my new lift pump?
