This vacuum-operated fuel pump is designed to transfer fuel from the tank to the carburetor on compatible riding mower, lawn tractor, zero-turn mower, 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 widely used Briggs & Stratton 808656 / 597338-style fuel pumps. Always confirm the original part number, hose routing, port orientation, and mounting pattern before ordering.

- Shut off the fuel supply, cool the engine, and disconnect the spark plug or battery before service.
- Mark the fuel and pulse hoses so each line is reconnected to the correct port.
- Use approved fuel line and clamps; replace damaged or leaking hoses.
