BYD Qin Pro Fuel Version Fuel Tank Cap Assembly | Fuel Filler Cap OEM Spec

This product is specifically designed for the fuel system of the BYD Qin Pro fuel version (2018-2022 models with 1.5L/1.5T engines). It is a sealing component installed at the left rear fuel filler opening—the fuel tank cap assembly. Although a seemingly small and unassuming component, the fuel filler cap carries significant safety and practical importance—it seals the fuel tank, preventing fuel evaporation and intrusion of dust and moisture, while ensuring smooth refueling.

The BYD Qin Pro fuel version features a fuel filler located at the left rear side of the vehicle, with a push-to-open design. A fuel filler cap actuator controls the locking/unlocking action, and a fuel filler door release handle is located under the driver's seat for manual operation. The Qin Pro DM plug-in hybrid version features a fuel filler on the left and a charging port on the right, forming a symmetrical "fuel on left, charge on right" layout.

As a professional manufacturer of automotive fuel system parts, we develop and produce strictly according to BYD OEM technical standards, offering a full range of fuel filler cap components including the fuel tank cap actuator, fuel filler cap cover, sealing gasket, and actuator harness. All parts are IATF 16949 certified, with OE numbers precisely matching the original vehicle for direct replacement of damaged, stuck, or actuator-failed original fuel filler cap assemblies.
