This vacuum-operated fuel pump is designed to transfer fuel from the tank to the carburetor on compatible Honda-powered riding mowers, commercial mowing equipment, and other small-engine applications. The three-port diaphragm design uses engine crankcase pulses to provide reliable fuel delivery without an electrical connection. Its durable black plastic body and direct-replacement mounting pattern make it suitable for replacing Honda 16700-ZT3-013-style fuel pumps. Always confirm the original part number, engine model, hose routing, port orientation, and mounting pattern before ordering.
