Good To Know

Q: How do I know if my generator needs a new fuel pump? A: Common signs include a crank with no start, surging under load, or weak fuel flow at the carburetor. Testing for voltage at the pump connector while cranking helps confirm the diagnosis.

Q: Does the pump come with wiring or fittings? A: The pump is supplied as the unit shown, so reuse your existing connector and fuel lines. Match the inlet and outlet orientation to your old pump before installing.

Slight variation in finish or dimensions may occur between production runs, and fit can depend on serial number, so confirm compatibility before ordering.
