fuel filter? Let's take a look.

Fuel filter is a kind of consumable. In the process of using the vehicle, it needs to be replaced and maintained regularly, otherwise it will not play a qualified protection effect. For the specific replacement cycle, please refer to each filter supplier. According to the instructions on the product, it is recommended to replace the car every 20000 kilometers.

fuel filter? Let's take a look.

If the filter is installed in the fuel line, it is called an external filter; on the contrary, the internal filter refers to the filter installed inside the fuel pump and fuel tank. The fuel tank inlet filter or its protective sleeve is generally considered to be a maintenance-free component.

The fuel filters of many imported cars use a drum tube connection. In order to connect the reliability of the seal, the same gasket must not be used repeatedly, in addition, even if a brand new gasket is used. When the fuel system needs to replace the "O" ring, it is necessary to ensure that the specification and model of the "O" ring are correct, and check whether the elasticity and hardness of the ring are appropriate.

The no-loop fuel system has only one internal filter (in the fuel tank). Although this multi-in-one (all-in-one) pump, filter, and delivery unit are expensive, when fuel When the delivery is blocked or the engine performance is reduced as a result, proper maintenance and maintenance must also be carried out in time. At the same time, check all fuel lines for faults, cracks and crimp of hose clamps.

What are the precautions for buying a fuel filter? Let's take a look.

1. Before purchasing goods, please be sure to verify the car model, displacement and other information to ensure that you can buy a correctly selected model of accessories.

2. During the maintenance of the fuel filter, the individual and the oil, machine filter, and air filter should be changed at the same time.

3. Choose high-quality fuel filters. Inferior fuel filters often lead to poor fuel supply, insufficient vehicle power or even flameout, and impurities are not filtered. After a long time, the oil circuit and fuel radiation system will also be eroded and damaged.
