BYD's fuel pump removal method: 1. The fuel pump repair hole is located in the trunk. Open the trunk lid and remove the floor mat. Use a flat-head screwdriver to pry open the fuel pump cover from the edge; 2. Disconnect the fuel pump electrical connector, press the buckle button, and quickly disconnect the fuel supply and return pipe connectors; 3. Use a fuel tank lock ring wrench to remove the lock ring, release the fixing buckle, and then remove the fuel level sensor unit, fuel filter, and fuel pump assembly. BYD is a Chinese automobile brand, mainly producing commercial and family cars as well as batteries. Its logo is elliptical in shape and incorporates light and shadow elements, highlighting the innovation, technology, and corporate culture essence of BYD automobiles, infusing the BYD brand with new connotation and vitality.

Disassembling a BYD fuel pump, I did it myself last time and found it quite interesting. Remember to start with safety: turn off the engine and disconnect the negative battery terminal to prevent sparks. Then release the fuel pressure by loosening the bolt on the fuel pump cover or unplugging the electrical connector to vent. Prepare your tools: wrenches, screwdrivers, and a special fuel tank cap tool, as the BYD fuel pump is usually located below the fuel tank opening. Remove the rear seat or carpet, carefully pry open the cover plate, and avoid damaging the sealing ring. If the retaining ring is metal, use a wrench to slowly unscrew it; if it's plastic, just pull it off with force. Next, disconnect all electrical connections and steadily remove the fuel pump, making sure no residual gasoline spills out. When reinstalling, check the new O-ring seal to ensure there are no leaks. The whole process is a bit time-consuming, so it's recommended to do it in a well-ventilated area and wear gloves for hand protection. If you lack experience, proceed with caution and seek professional repair if any issues arise.

I often handle fuel pump removal at the repair shop. Safety comes first: always turn off the engine and disconnect the battery to reduce fire risk. Then release fuel pressure: locate the fuel tank cap or fuel line connector, loosen the bolt to vent. BYD's fuel pump is fixed inside the tank, accessible after removing the seat to expose the cover plate; use tools to remove the retaining ring, and take photos to record wiring connections before extraction. Check the old pump's connectors and wiring, being careful not to break them; during installation, align the seal and tighten the ring properly to avoid leaks. Recommended tools include socket sets and breaker bars. After completion, start the car and test run for a few minutes to ensure no abnormal noises. BYD vehicles commonly experience fuel supply issues due to pump wear—replacement often restores smoother power. Remember to ventilate the area and prevent fire hazards; stop immediately and clean up any fuel leaks.

Here's a simple removal method: First, park and turn off the engine, then disconnect the negative battery cable. Open the trunk or rear seat to locate the fuel tank cover. Use tools to remove the cover plate screws and take off the cover. You'll see the fuel pump retaining ring; twist it open. Then gently unplug the electrical connector and remove the fuel pump. Don't forget to relieve fuel pressure beforehand by loosening the fuel line bolt or disconnecting the fitting. Wear gloves throughout the process to protect your hands. After removal, check if the pump head is damaged and clean any debris. BYD vehicles have easily accessible fuel pump locations, but beginners should follow the manual steps. Safety first – ensure good ventilation and keep away from fire sources. Remember to securely connect the electrical wiring and seal when installing the new pump.
