There is a protruding knob under the fuel water separator, turn it on until the gasoline comes out:
1. If there are water and impurities in the gasoline, the parts of the fuel system will corrode and rust due to the water in the fuel. Removing water from the diesel is very important for trouble-free operation of the fuel system and prolonged service life;
2. The fuel water separator is mainly based on the density difference between water and fuel, and uses the principle of gravity sedimentation to remove impurities and water. There are also separation elements such as diffusion cones and filters inside;
3. The fuel water separator also has other functions, such as pre-heating the fuel to prevent waxing and filtering impurities.

1. Diesel filter element is one of the important components to ensure the quality of diesel engine oil;
2. Definition: Diesel filter element is one of the important components to ensure the quality of diesel engine oil;
3. Classification: There are two main types of diesel filter elements, spin-on type and replaceable type;
4. Function: The high-quality diesel filter can effectively block the dust and moisture contained in the diesel, and can extremely effectively extend the service life of the fuel injection pump, diesel nozzle and other filter elements.
