I guess time will tell.

I will leave the engine-mounted mechanical lift pump in situ in case one day it will be needed again. Perhaps it's just better to take it off to save wear on the diaphragm and blank off the aperture?


Right, if you leave it on with no fuel running through it the diaphragm may get brittle and break. I would think 5 pounds of pressure would be plenty to get through both filters. One article I read recommended a filter between the tank and the suction side of the pump to protect the pump mechanism. Or, some pumps may have an integral filter?
