Sup fellas. Just recently replaced my mech. fuel pump. now I think its going bad again, maybe just a faulty one. I have a couple different fuel pumps that I use to drain gas and other such things. Could I some how bypass the old mech. one and install an electrical one? the pumps I have run off a car battery and could I hook it up to my ignition? '87 4.2 stock carter, weber will be installed shortly Also could a kinked vent hose that goes to the gas cap make my truck run different?
