There are three positions for different models. The first is in the engine room, the second is under the chassis of the car, which is close to the fuel tank, and the third is in the fuel tank, which is connected to the gasoline pump. The role of fuel filter:
1. Clean fuel Compared with carburetor vehicles, EFI vehicles require cleaner fuel, because even the smallest impurities will wear down the precision parts in the EFI system;
2. Therefore, EFI vehicles need a special gasoline filter, which filters impurities in the fuel to prevent them from entering the injection valve and cold start valve. The gasoline filter is an important part of the electronic fuel injection system. Only the gasoline filter that is matched by the original factory or exceeds the matched quality can provide the clean fuel required by the electronic injection system, so as to optimize the performance of the engine and at the same time provide the best protection for the engine;
3. The importance of gasoline to the car is the same as the importance of food to the human body. Without the supply of gasoline, it is difficult for a vehicle to move at all;
4. In addition, in terms of gasoline products, if the oil is not good and the gasoline contains more impurities, this will cause damage to the fuel injector, fuel pump, fuel pipeline and other components in the engine, thereby affecting the normal operation of the fuel system;
5. Simply put, the function of the gasoline filter is to filter out solid impurities such as iron oxide and dust or water contained in the gasoline. On the one hand, it can reduce the chance of the fuel injector being blocked by impurities, on the other hand, it can also ensure the quality of gasoline flowing into the fuel system.
