Where is the fuel pump

The fuel pump is located in the car's fuel tank, which is located in the rear seat of the car, or under the trunk. The main function of the fuel pump is to supply fuel to the engine. The fuel pump delivers high-pressure fuel to the fuel distribution pipe to ensure continuous fuel supply to the fuel injector. The fuel pump is composed of an electric motor, a pressure limiter, and a check valve. The electric motor actually works in the fuel in the fuel pump housing. Don’t worry, because the housing There is nothing in it that can be ignited. The fuel can lubricate and cool the fuel motor. The oil outlet is equipped with an inspection valve. The pressure limiter is located on the pressure side of the oil pump housing with a passage leading to the oil inlet.

Built-in type: integrated with the assembly, installed vertically in the tank, featuring low noise, not easy to generate air resistance, safety, and simple pipeline installation;

External type: The oil pipeline connected in series outside the fuel tank features large installation freedom, convenient replacement, and high air tightness requirements;

At present, the fuel pump of most models is installed in the fuel tank of the car. The fuel pump driven by electricity is composed of a pump body, a permanent magnet motor and a shell. When the permanent magnet motor is energized, it drives the pump body to rotate, sucking fuel in from the fuel inlet, flowing through the inside of the electric fuel pump, and then pressing it out from the fuel outlet to supply fuel to the fuel system. The fuel flows through the inside of the electric fuel pump to cool the armature of the permanent magnet motor, also known as the wet fuel pump.
