The diesel filter is located under the engine protection plate, and the filter is located in the engine compartment at the front of the engine. Note:
1. The built-in gasoline filter is usually installed at the gasoline pump and installed in the fuel tank. Because it is more troublesome to replace and the cost is relatively high, it is usually replaced once every 10W km;
2. The external gasoline filter is generally installed on the top of the gasoline pipe, and it is more convenient to replace it. Generally, it is replaced every 2W kilometers;
3. The main function of the gasoline filter is to filter the impurities in the gasoline, so that the combustion of the gasoline entering the engine will be cleaner, the combustion will be more sufficient, the formation of carbon deposits in the cylinder will be reduced, and the power will be better input.

1. The main function of gasoline filter is to filter impurities in gasoline. If the gasoline filter is too dirty or clogged, the main symptoms are;
2. When the accelerator is opened, the force is slow, or it is impossible to get up, and the car is difficult to start;
3. Gasoline is made from crude oil through a complex process, and is then transported to various refueling stations through a special route, and finally to the owner's fuel tank. During this process, impurities in gasoline inevitably enter the fuel tank, and in addition, impurities will increase with the use of time. In this way, the filter used to filter the fuel will appear dirty and full of dregs, which will greatly reduce the filtering effect;
4. Therefore, it is recommended to replace it when the number of kilometers is reached. If it is not replaced, or the replacement is delayed, it will inevitably affect the performance of the car, cause the oil circuit to be blocked, the car is not easy to refuel, etc., which will eventually lead to chronic damage to the engine, and even the engine needs to be overhauled.
