Automotive gasoline pump wiring harness is mainly composed of multiple strands of copper flexible wire, the exterior is wrapped by plastic to provide the necessary protection and insulation 12. This design ensures that the harness can still work stably in high temperature and high pressure environments.
How it works :
The gasoline pump harness controls the supply of fuel by transmitting signals. It consists of four main wires: two fuel level sensor wires (float wires), one power cord, and one lap wire 3. The two sensor cables are thinner, and the power and base cables are thicker. These lines transmit signals to the oil pumps to control the fuel supply to the car. The fuel pump is responsible for extracting fuel from the tank and pressurizing it to the supply line. It works in conjunction with the fuel pressure regulator to ensure that the fuel system maintains proper pressure
