The Role of The Fuel Filter

The fuel filter removes solid impurities such as iron oxide and dust contained in the fuel to prevent the fuel system from clogging (especially the fuel injection nozzle). Reduce mechanical wear, ensure stable engine operation and improve reliability. 

Even if the diesel oil is cleaned before being added to the diesel engine fuel tank, it is clean, but during the fueling process, due to factors such as fueling tools, fueling environment, and unclean fuel tank ports, the diesel oil will still be polluted. Impurities deposited in the fuel system and suspended sediment in the air can also contaminate the diesel, so fuel filters on the car are essential, not to mention that diesel is not necessarily really clean before it is added to the fuel tank.

Types of fuel filters:

There are three types of fuel filters: diesel filters, gasoline filters and natural gas filters.
