Naraku 15mm Fuel Petcock Valve | Zuma Kymco Vespa

Solve hard-starting and fuel starvation issues caused by a failed petcock diaphragm with the Naraku 15mm Fuel Valve. Unlike cheap replicas, the Naraku valve closes completely tight and opens reliably when vacuum is applied — ensuring consistent fuel delivery to your carburetor. The 84mm filter tube extends into the tank to draw fuel cleanly, and the 15mm push-in mount seals with an O-ring for a leak-free fit. Compatible with a wide range of 2-stroke and 4-stroke scooters from Aprilia, Kymco, Piaggio, Vespa, and more.
