What Causes Abnormal Noise in the Car Fuel Tank?

[SanAutumn]

Abnormal noise in the car fuel tank may be the sound of the fuel pump working. If the noise is not the current sound of the fuel pump motor, it could indicate an abnormal fuel pump that needs replacement. Symptoms of an abnormal fuel pump include: 1. Weak vehicle acceleration, especially with noticeable hesitation during rapid acceleration. 2. Difficulty starting the vehicle, including failure to ignite or hard starting. 3. The engine fault light on the vehicle's instrument cluster remains constantly illuminated. Additional Information: As the most fundamental component in the engine fuel supply system, the fuel pump is responsible for drawing fuel from the tank during engine operation and delivering it continuously through the fuel supply line to the engine at a certain pressure. The high-pressure fuel pump then performs secondary pressurization, supplying a measured amount of fuel to each cylinder according to the engine's working sequence.
