Hero Genuine Destini 125 / Destini 110 BS6 OBD2 Fuel Unit Assembly

Replace a faulty, inaccurate, damaged, or non-working fuel level sender with the Hero Genuine Fuel Unit Assembly. This genuine Hero unit is fitted in the fuel tank assembly on confirmed newer Destini 125 and Destini 110 scooter variants and helps the fuel gauge show fuel level correctly when installed with the right wiring and tank setup.

The part is commonly searched by scooter owners and mechanics as a fuel unit, fuel gauge unit, fuel sender unit, petrol level sensor, fuel level sensor, or fuel meter sensor. Choosing the correct genuine Hero part helps maintain proper float movement, connector compatibility, tank fitment, and fuel-level reading accuracy compared to universal or locally matched sensors.

This SKU should be matched carefully with the old fuel unit and scooter variant before ordering. Fuel units can differ by tank design, float arm length, connector type, resistance calibration, mounting pattern, and model generation, so part-number confirmation is important for correct fitment and fuel-gauge operation.
