Structure and principle of electric fuel pump

The electric fuel pump can be divided into two types according to the installation form: the tank external type and the tank internal type. The oil tank external electric fuel pump is installed outside the oil tank and connected to the oil pipeline. The BUILT-IN ELECTRIC fuel PUMP IS EMBEDDED IN THE fuel TANK and immersed IN the fuel. This prevents gas resistance and fuel leakage, and makes little noise. In addition, the built-in type also has a small tank in the fuel tank, and the fuel pump is placed in the small tank, which can prevent the fuel pump from inhaling air and producing air resistance when the car turns or tilts due to lack of fuel.

Whether the fuel tank is built in or the tank is external electric fuel pump, its structure is basically the same, is composed of pump body, motor and housing and other p
