[QUOTE="roblarss, post: 103717, member: 9491"] I am noticing that recently I am most likely having a fuel pump issue. Drop in power, sometimes the rpm wont go past 50%. I cleaned the inline filter and the one on the pump, proved the fuel lines aren't plugged. Took the pump apart and found the plastic check plungers are pitted. I have also noticed that the fuel return line off the injector pump isn't flowing anything. This is the pump in question. https://fuel-inject.com/supply/zexel.1052204742-bosch.9440610030/ Since I cant locally find parts I am looking at putting in an electric pump and just bypass the mechanical one. Is there a pressure rating I should look for. I have found pump that put out 5psi and some 10-12 psi. Same as different flow numbers. Does the injector pump function fine with a different inlet pressure? What have others done. Thanks [/QUOTE]
