The replacement price of the fuel pump is about 1000 yuan:
1. When the pump core is damaged, when the fuel supply system is working, when the key door is opened, there is no sound of the gasoline pump running;
2. When the pump body is damaged, because the pressure relief and fuel pressure cannot reach the specified fuel pressure value, it cannot be atomized well, so the engine cannot be started;
3. Don't wait until the gasoline light alarms and don't refuel, because the gasoline pump relies on gasoline to conduct heat and cool down. When the gasoline level is too low, it will not be able to cool down and dissipate heat, reducing the service life;
4. The failure of the gasoline pump is always related to the quality of the oil, the way of refueling, the amount of refueling and the frequency of refueling, so we must pay attention to refueling correctly and refueling well to ensure the service life of the car oil pump.

Fuel pump is a professional term in the auto parts industry. It is one of the basic components of the fuel injection system of electronic fuel injection vehicles and is located inside the fuel tank of the vehicle. The fuel pump works at startup and when the engine is running, if the engine is stopped and the ignition switch is still ON, the HFM-SFI control module turns off the power to the fuel pump to avoid accidental ignition.

The fuel pump delivers high-pressure fuel to the manifold, ensuring a continuous supply of fuel to the injectors. The function of the fuel pump is to suck out the fuel from the fuel tank, pressurize it and deliver it to the fuel supply pipe, and cooperate with the fuel pressure regulator to establish a certain fuel pressure.
