4 Fungsi Filter Bahan Bakar Mobil dan Cara Membersihkannya

The car fuel filter is one of the components of the fuel system that plays a significant role; its presence will ensure the car performs well. However, despite its importance, many vehicle owners are unaware of its function. 

In fact, if the fuel filter is not properly maintained, it can be detrimental to the driver. Indeed, this part is difficult to open, but it can still be cleaned to remove various types of accumulated dirt. 

If the dirt has accumulated too much, you can replace the filter with a new one, as the buildup of dirt will be difficult to clean and will take a very long time. 

Function of the Car Fuel Filter

There are several important functions that this component has, including:

1. As a dirt filter

The main function of this component is to filter out dirt present in the fuel. Without the filtering process, various problems will arise in the vehicle. 

2. Filtering water elements

Another function of the car fuel filter is to filter out water elements. Usually, these water elements are also found in the fuel. If the fuel mixes with water, the car's performance will be hindered. 

Thus, with the presence of this fuel filter, the presence of water will be filtered out, and the risk of fuel and water mixing can be avoided. This keeps the car's performance stable.

3. Reducing fuel flow speed

Another important function of the fuel filter is to reduce the speed of fuel flow. This allows the car to run steadily under various road conditions. Additionally, with this reduction in fuel flow, harmful components do not enter the fuel chamber. 

As we know, components that enter combustion can cause deposits at the bottom. Therefore, the fuel filter is very much needed. 

4. Preventing fuel filter clogging

When the fuel filter gets clogged, the resistance in the fuel flow can increase. If this happens, more fuel enters the carburetor, leading to higher fuel consumption. 

When the engine runs at high RPM, it requires a significant amount of fuel. This is what causes the engine power to decrease.

How to Clean the Car Fuel Filter? 

Actually, the process of cleaning the fuel filter can be done by yourself at home. Here are some steps you can follow:

1. Locate the fuel filter

Before cleaning the filter, first find the fuel filter. The fuel filter can be located in different places. There are filters that have flow to the injection system, and some are located elsewhere. 

2. Open the fuel line

To clean the fuel filter, you can start by opening the fuel line. The clamp can be tightened using a flat screwdriver. Then, close it with the clamp. 

3. Prepare a container

Place a container right under the fuel filter, then open the clamp cover. When opening the clamp cover, pull the hose from the filter and let the fuel flow out by itself. Then start cleaning the fuel filter. 

How about that? Cleaning the car fuel filter is not as difficult as it seems, right? However, if you still have trouble cleaning it, you can take the car to a Daihatsu authorized workshop

In addition to maintenance, you can also purchase genuine spare parts here. Moreover, you won't have to wait long for service queues, as Daihatsu offers online service booking.
