Just a note to Santerre (J.F.) above about NOS pumps. If they are vintage, the diaphragm will not be resistant to ethanol and will fail prematurely. When that happens it not only quits pumping but dumps gasoline into the crankcase. I think it would be advisable to replace the diaphragm of an NOS pump before installation using one of the modern kits. You will then have the very best pump obtainable.
