Be Sense-able: OEM Fuel Level Sensor
Restore your dashboard's accuracy with the Blue Line Fuel Sending Unit. 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.
