Product Overview
The fuel pump moves fuel from the tank toward the carburetor or injection system so the engine receives a steady supply. Hard starting, hesitation under load, fuel starvation or an engine that loses power can point to a weak supply pump after filters and lines have been checked. Replacing the failed component can restore normal operation without changing unrelated parts that are still serviceable.
Fitment can vary by engine build, machine serial number and production revision. Use the model information below together with the original part number, connector or mounting layout when applicable.
