A fuel pump is an important device in a car's fuel supply system.

Its function is to pump fuel from the fuel tank to the engine so that the engine can run continuously. The reason why many people call a fuel pump a fuel pump is because of the pump's working characteristics, which will make a ticking sound when the key is turned. However, at present, fuel pumps are popularly driven by gears and electric motors assembled as a single set with a float to measure the fuel level, which car users will not hear the ticking sound. However, Thai mechanics still prefer to call it a fuel pump because it is easy to understand.

Why do I have to change the fuel pump?

The fuel pump is a device that works all the time when the engine is running. Therefore, it is possible for it to deteriorate according to its age. Factors that cause the fuel pump to deteriorate include:

Lifespan - Generally, the fuel pump's lifespan is around 100,000 - 150,000 kilometers or about 5-7 years, depending on the make and model of the car and its maintenance.

Frequently letting the fuel run out - The fuel pump relies on the fuel in the tank to cool it. If the fuel tank is often empty, there is a high chance that the fuel pump will not be able to suck the fuel in the tank and cause the fuel pump to overheat and deteriorate prematurely.

The fuel pump is a part that does not need to be maintained like other parts. However, car users can extend the lifespan of the fuel pump by choosing to fill up with quality fuel and avoid driving with too little fuel left in the tank.
