Specifically designed for GY6 50cc (139QMB) and 150cc (157QMJ) scooters, this fuel level sensor features the common 3-tab \"twist-on\" mounting interface. If your fuel gauge is stuck on empty or fluctuating wildly, a corroded or failed sending unit is the likely culprit. This OEM-spec replacement ensures your gauge reflects the true level of your tank, preventing unexpected \"out-of-gas\" breakdowns. Technical Performance Features Precision Float Arm: Engineered with a high-sensitivity potentiometer to provide a smooth, linear resistance signal to your analog or digital fuel gauge. Twist-On 3-Tab Interface: Designed for modern Chinese-manufactured tanks that utilize a metal locking ring (sold separately) rather than traditional bolts. Fuel-Resistant Components: Features a high-density float and reinforced wiring harness designed to withstand long-term immersion in modern ethanol-blended gasoline. Plug-and-Play Wiring: Comes with a standard electrical connector for a seamless interface with your scooter's factory wiring harness.
