Have a look at the working of the car fuel filter below:

Through the fuel inlet opening, fuel enters the filter. The liquid then flows down the annular space between the element and the casing. Because there is frequently little space between the filter component and the housing, the fuel must pass through the filter element. Tiny particles in the fuel, such as dirt and metal debris, remain on the surface of the pleats during the filtration process. Water, on the other hand, settles in the metal casing's bottom. Water has a higher density than fuel, which explains why it sinks to the bottom. At the bottom of the metal, the casing is a valve. 

By opening the valve, the water that has settled at the bottom is emptied. As a result, if water unexpectedly mixes with fuel and reaches engine parts, it will cause overheating and premature wear of the engine. The fuel outlet removes the clean gasoline from the filter after the entire procedure is completed. The next step is to combine the clean fuel with air in the injector chamber to create an air-fuel mixture. The diesel engine fuel system goes through two rounds of filtration because diesel contains more impurities compared to gasoline. Therefore in diesel engines, primary and secondary filters are used. As a result, the possibilities of pollutants entering the fuel are practically zero.

• There are a lot of automobiles in which it is very straightforward to change the filter and in some cars, there might be a need to fill the filter housing with fresh fuel or use a hand pump to draw fuel through the system when you swap filters, or else it can be difficult or sometimes even impossible to start.
