Model Fitment
Fits any fuel tank with the matching M16 × 1.0 thread size and pitch. GY6 and QMB scooters from 50cc to 170cc are common applications, not displacement limits.
Application families include 139QMA, 139QMB, 1P39QMB, 1P39QMA-2, YN139QMB, JJ1P39QMB, 139FMA-2, BD1P39QMB, BN139QMB, 147QMD and other matching GY6/QMA/QMB applications.
Check the tank thread first, then confirm hose routing, seal seating and filter clearance for installation. Engine code alone does not determine the tank's thread size.
