Fuel Filter: Description and Operation







In-Line Fuel Filter
The fuel filter is located in the fuel feed pipe, between the fuel pump and the fuel injectors. The paper filter element (2) traps particles that may damage the fuel injection system. The filter housing (1) is made to withstand maximum fuel system pressure, exposure to fuel additives, and changes in temperature.
