The Sierra 18-7804 Fuel Pump Kit is a direct-fit rebuild kit for Mercury outboard engines, designed to restore fuel pump function during a routine service or repair. It cross-references to OEM number 23014A1, so it drops in as a straightforward replacement for the factory kit. The kit is supplied as a compact, lightweight package (0.01 pounds) intended for boat owners and marine technicians performing fuel pump maintenance rather than a full pump replacement. Keeping the fuel pump sealed and functioning correctly is important for reliable engine performance, and using a properly matched rebuild kit like the Sierra 18-7804 helps avoid fuel leaks or pump failure caused by worn seals and gaskets.
