Car fuel water separator cleaning:
1. For the first stage of the fuel water separator, it is generally a parallel plate, which can be opened and cleaned;
2. If the second level is a filter element, it is also divided into situations. If it is a one-time one, you can only apply for replacement of spare parts. Some filter elements can be opened and cleaned by themselves. However, the port state and the flag state require a spare filter element for pollution prevention during inspections. The second level also depends on the medium to absorb. This kind of medium can be taken out, cleaned, dried, and reloaded. This is not recommended because the effect will be worse; if it is a medium, it is recommended to apply for a medium and replace it with a new one, which is very simple;
3. Some fuel water separators have heating equipment. Fill water before cleaning. Be careful not to close the heating when heating, otherwise the pressure increase will damage the equipment and make it easy to clean.

The role of fuel water separator:
1. The fuel water separator is a separator that uses the principle of gravity sedimentation to remove impurities and moisture based on the density difference between water and fuel. There are also separation elements such as diffusion cones and filters inside;
2. The fuel water separator has other functions, such as pre-heating the fuel to prevent waxing, filtering impurities, etc.;
3. It is a kind of fuel filter, and its main function is to remove the moisture in the diesel, so as to reduce the failure of the fuel injection nozzle and prolong the service life of the engine;
4. The fuel water separator can only separate the fuel from water and separate the water in the oil, which has a certain effect on improving the engine oil burning.
