In order to ensure the effective protection of the fuel filter, the car usually needs to be replaced every 20,000 kilometers. If the fuel filter is not replaced for a long time, it may cause the fuel filter to be blocked, and the fuel supply pressure of the car will be reduced. If the fuel supply is insufficient, the engine power will drop.
In addition, the clogging of the fuel filter can also cause poor fuel atomization, resulting in an imbalance in the mixture ratio and insufficient combustion, resulting in engine carbon deposits. Therefore, if the fuel filter is replaced irregularly, it will cause a series of effects, spreading from the fuel supply to the ignition system and the exhaust system.
Fuel filter is divided into built-in and external type
At present, most models have an external fuel filter, which is connected to the oil return pipe on the outside of the outer fuel tank. The biggest advantage of this type of fuel filter is that it is easy to replace.
The built-in fuel filter is located in the fuel tank. It is not convenient to replace. Non-professionals may damage the car. However, the biggest advantage of this type of fuel filter is that the gasoline has a high passing rate and is not easy to cause blockage, so the frequency of replacement can be Proper extension, not without replacement.
Precautions for replacing the fuel filter:
1. Before dismantling, be sure to follow the manufacturingbusinessPerform the specified steps to release the residual pressure in the fuel system. Otherwise, it is easy to cause gasoline overflow, and in serious cases, personal safety will be endangered;
2. During the replacement process, do not smoke or use an open flame nearby, otherwise there will be certain safety hazards;
3. The fuel filter has arrow marks on the inlet and outlet ports, so please do not install it backwards when you replace it;
4. After installation, be sure to check the sealing of the interface to avoid oil leakage.
