Replace a failed electric fuel pump or upgrade to a simpler, more reliable system with the 101 Octane Universal Vacuum-Operated Fuel Pump. Powered by engine vacuum rather than electricity, this diaphragm-style pump requires no wiring and works with any engine that produces intake vacuum. Compatible with any scooter, ATV, or small engine using 1/4" (6mm) fuel lines.
The center brass fitting is the vacuum connection port. Fuel inlet and outlet are marked by directional arrows on the underside of the pump body — always observe flow direction during installation.
