Product Overview
This pump pulls fuel from the tank and feeds it toward the injection system. It is commonly replaced when an engine becomes hard to prime, loses power or has repeated fuel-starvation problems.
Before replacing the pump, check the fuel filter, hoses and tank pickup for restrictions or air leaks. Those problems can make a good pump look weak and can cause the same hard-start or power-loss symptoms.
