I have a 88 2.6 4 w. Where the fuel leaks out of carb. and drains back to tank after it sets for a few days. You have to grind it for a couple of minutes or have to prime the carb. to get it to start. Runs ok when started. Now it won't start at all and appears the pump is not pumping any gas. My question is should I replace with a stock fuel pump or change it over to a external electric pump? My other question is if I go with a electric pump, what do I do with extra fuel pump outlet on the old pump? Are they any diagrams showing this and which way would you go?
