The fuel filter works by filtering the fuel through an internal filter element. When the fuel is pumped from the tank, it passes through the filter, which blocks the impurities, allowing only pure fuel to pass through and enter the fuel injection system of the engine. The design of the filter element usually uses high efficiency filter paper to improve the filtration efficiency and flow area
The fuel filter assembly plays a crucial role in the automotive fuel system. Its main function is to filter impurities in the fuel, prevent the blockage of the fuel system, and ensure the normal operation of the engine. Specifically, the fuel filter filters the fuel through an internal filter element, blocking impurities such as rust, dust, moisture, and gum in the fuel, ensuring that pure fuel enters the engine's fuel injection system, thereby protecting the engine from wear and other damage
