What Causes Fuel Tank Noise?
1 Answers
Fuel tank noise causes: External noise indicates the fuel tank is not securely fastened; internal noise suggests issues with the electric fuel pump, such as problems with the motor or gears. Below are refueling precautions: 1. Do not wait until the fuel light comes on to refuel: Since the fuel pump is located inside the tank, it operates at high temperatures when continuously working, and being submerged in fuel helps cool it effectively. When the fuel light comes on, it means the fuel level is below the pump. Waiting until the light comes on to refuel each time can shorten the pump's lifespan. Too little fuel or running out can even burn out the pump. 2. Choose reputable gas stations: When selecting a gas station, prioritize Sinopec and PetroChina. Avoid unknown brands, as they may offer local fuel that claims to be 93-octane but doesn't meet the standard, resulting in shorter mileage.
