Fuel Pump Mobil Bermasalah? Cek Penyebab dan Solusinya

The maximum performance of a car is determined by the performance of each component within it, such as the fuel pump. As is known, the fuel pump is a car component that functions as a pump for fuel from the tank to the engine's combustion chamber. If this component has problems, it is certain that the performance of the engine's combustion chamber will not be optimal, making it difficult to start the car, causing the car to stutter while driving, or even preventing the engine from starting at all. So what causes the car's fuel pump to have problems? For more details, please pay attention to the following review.

Causes of Car Fuel Pump Problems and How to Overcome Them

There are several factors that cause car fuel pumps to have problems. Here are the complete causes along with how to address them.

1. Use of low-quality fuel

A problematic fuel pump often occurs because car owners use low-quality fuel or fuel that does not meet the car fuel standards. As is known, each car has its own fuel standard, whether it is diesel or gasoline. 

For example, if your car has a gasoline fuel standard with an RON of 92, then you must use fuel with the appropriate RON or a higher RON. If you use gasoline with a lower RON, the fuel tank will become crusty. 

This causes the fuel pump to become clogged with dirt or crust that is carried when the fuel pump is pumping fuel. To address this issue, you only need to use fuel that meets the car's standards.

2. Stale fuel

A problematic fuel pump can also be caused by stale fuel conditions. As is known, when you let the fuel tank run low (not fully filled) for a long time, evaporation will occur inside the tank. 

This evaporation process can produce other additives, especially if the fuel tank seal is not tight. This can cause the fuel to mix with water from the evaporation process. This condition will make the fuel stale, reducing its quality and causing corrosion in the tank and fuel pump. As a result, the fuel pump becomes porous and clogged with dirt, leading to decreased fuel pump performance.

To address this, you should always fill the fuel tank completely. Make sure you do not leave the fuel tank empty or not fully filled for a long time. If you do not want to use the car for an extended period, you should still warm up the engine by starting the car twice a week for 5 minutes.

3. Age factor

Another cause of fuel pump problems is the age of use. As is known, the more often the fuel pump is used, the performance of that component will decline. Whether due to leaks in the fuel pump or it has reached its wear period. To address this issue, you need to perform fuel pump replacement. You can buy a fuel pump at an automotive store and install it yourself. However, if you are not skilled at doing it, you can ask for help from a skilled mechanic by taking your car to a workshop.

Thus, here are some causes and ways to address problematic car fuel pumps. Speaking of the best workshops for fuel pump maintenance and repair, you should try the services from Daihatsu workshops. Because at this workshop, they are not only experts in solving fuel pump problems but also in the overall maintenance and repair of cars.
