BYD Destroyer 05 Electric Fuel Tank Cap (Fuel Filler Cap Assembly / Fuel Tank Actuator)

As a professional automotive fuel system parts manufacturing factory, we proudly present the Electric Fuel Tank Cap designed specifically for the BYD Destroyer 05 (5th Generation DM Super Hybrid) .

The fuel tank cap is an important component of the vehicle's fuel system, installed at the refueling port on the right rear side of the vehicle. It seals the fuel tank to prevent fuel vapor from escaping and keep out external contaminants. The Destroyer 05, as a plug-in hybrid model, has a 48-liter fuel tank capacity and is equipped with an electric unlocking mechanism that controls the opening and locking of the fuel filler cap through an in-vehicle switch or vehicle unlock signal.

According to owner complaint information, the Destroyer 05 has experienced issues such as the fuel cap not opening and excessive internal pressure preventing refueling. 4S store service typically resolves these issues by replacing the fuel cap assembly. Some owners have also reported the fuel cap connecting wire breaking (after fewer than 10 refueling operations), indicating that the fuel cap and its connecting components are wear parts.

In daily use, the electric fuel cap is exposed to outdoor elements and susceptible to dust, rain, and car wash chemicals – leading to motor sticking, locking mechanism failure, and seal aging. Typical failure symptoms include: fuel cap won't open, won't close, and dashboard warning lights.

Our product is strictly developed to original Destroyer 05 OE specifications, featuring a high-strength engineering plastic housing + micro DC motor actuator with integrated position sensor and locking mechanism. The connector interface precisely matches the original 1:1 for direct replacement of damaged original parts, restoring normal fuel cap opening/closing function.
Strictly developed to original Destroyer 05 OE specifications, with mounting clip holes and harness connector interfaces precisely matching the original 1:1. No modification required – direct replacement for damaged original parts. Compatible with all 2022-2025 Destroyer 05 models, including 55KM/120KM range versions, Champion Edition, and Glory Edition.

According to owner complaint information, the Destroyer 05 fuel cap assembly is a common replacement part in 4S store aftersales service. Our product is a direct replacement for the original part with no additional modification required.
The fuel cap features an integrated micro DC motor actuator and position sensor, receiving signals from the vehicle BCM (Body Control Module) for precise opening/closing control. The actuator includes overload protection to prevent motor burnout from stalling. The position sensor provides real-time feedback on fuel cap status, ensuring accurate dashboard display.

The product passes durability testing (≥10,000 open/close cycles) for long-term reliability. The seal is made of oil-resistant EPDM rubber for excellent fuel corrosion resistance and sealing performance.

The fuel tank cap sealing ring is made of oil-resistant EPDM rubber, which fits precisely with the fuel filler neck to achieve full sealing of the fuel tank. According to vehicle specifications, the Destroyer 05 has a 48-liter fuel tank. Sealing performance directly affects fuel economy and emissions. Our products are manufactured in strict accordance with original factory sealing standards to prevent fuel volatilization and the ingress of external impurities.
