Sierra Fuel Pump 18-35437, Replaces 861676A1 and 861676T09, PWC Universal Fit

The Sierra Fuel Pump 18-35437 is an electric fuel pump built for personal watercraft (PWC) applications. It uses a glass body construction and a flange mounting design, positioned at the rear of the fuel system, to deliver reliable fuel flow to the engine. Its compact dimensions of approximately 0.39 x 0.39 x 0.39 inches allow it to fit into the tight engine bays typical of PWC units.

This pump is designed as a universal fit replacement, making it a straightforward swap for worn or failing fuel pumps on compatible PWC models. It directly replaces OEM part numbers 861676A1 and 861676T09, so buyers who have either of those numbers stamped on their original pump can order this part with confidence. The glass-body construction is intended to hold up to continuous exposure to marine fuel and the vibration and moisture common in watercraft engine compartments.
