Fuel Petcock Valve - M16x1.5, / GY6 50cc (139QMB)

Fuel Petcock Valve for GY6 and 139QMB Scooters

This vacuum-actuated fuel petcock is built for GY6 and 139QMB engines, which show up on many scooters. Its thread pitch is M16x1.5 and it has 2 ports, so it can serve as a simple swap-in replacement for a range of Taiwanese and Chinese scooters. Among GY6 50cc scooter parts, it handles the job of carrying fuel from the tank to the engine.

Design and Functionality

With two ports, this petcock manages fuel flow in a straightforward way. It runs on vacuum, opening and closing according to what the engine needs. That response is what keeps fuel moving properly while the scooter is running.

Installation Overview

The valve threads directly into the fuel tank, so it is a direct-fit part. Before fitting it, check the thread size and port count against your scooter so you know it will match. Doing this first helps you avoid fitting problems and makes sure it works as intended.
