Where is the fuel pump located in BYD S6?

The fuel pump in BYD S6 is located inside the fuel tank. Here is more information about the fuel pump: 1. Introduction: Among the four wires of the car fuel pump, two are for the fuel level sensor (commonly known as the float), one is for power supply, and one goes to the fuel gauge; the other two are for the fuel pump, one for power supply and one for grounding. 2. Fuel pump relay: The English abbreviation is PMR, and the full name is Pump-Motor-Relay. The fuel pump relay is used to control the power supply to the fuel pump. Modern cars generally use direct injection or port injection. Once the fuel supply meets certain requirements, the relay cuts off the fuel pump, thus controlling its operation. 3. Basic function of car relays: They act as an 'automatic switch' that uses a small current to control the operation of a larger current. In circuits, they play roles such as automatic regulation, safety protection, circuit switching, and more.
The fuel pump of the BYD S6 is usually installed inside the fuel tank, hidden in the rear chassis area. I think this design is quite smart because being immersed in fuel helps with heat dissipation and ensures stable fuel supply, making it much safer and more reliable than placing it outside. Sometimes, if the car has difficulty starting or suddenly stalls while driving, it might be due to a pump issue. Like in my previous experience, the car wouldn't start after multiple attempts, and a check at the repair shop confirmed it was a faulty pump. For safety, never attempt to dismantle the fuel tank yourself—fuel leakage is very dangerous, and it's much safer to let a professional mechanic handle the inspection. Also, try not to let the fuel tank stay completely empty for too long; keeping it about half full can extend the fuel pump's lifespan.
If you own a BYD S6, I recommend knowing that the fuel pump is located inside the fuel tank, specifically at the rear undercarriage of the vehicle. This design helps prevent the pump from running dry or overheating, ensuring smooth fuel delivery to the engine. If the pump fails, the car may experience difficulty starting or shaking while driving, and delayed repairs can lead to further issues. During routine maintenance, regularly inspect the fuel filter as it is connected to the pump—dirt buildup can accelerate pump wear. Also, check the fuel cap seal after refueling to ensure no air leaks. Overall, this is a standard layout, but professional assistance is recommended for repairs, as lifting the car or removing the rear seat may be required for access.
The fuel pump is located inside the fuel tank of the BYD S6, positioned in the rear underbody area. This design is quite common as it allows the pump to operate submerged in fuel, preventing overheating or dry running. If the pump ages, common symptoms include difficulty starting the car or unstable power output. It's recommended to have a mechanic inspect the fuel tank system during routine maintenance. For basic upkeep, ensure the fuel tank stays clean and avoid using low-quality gasoline.
