ABSTRACT:
In a fuel filter for an automobile, a filter element for filtering fuel is accommodated in a tubular filter case having a bottom surface and a side surface. A fuel heater is mounted on the side surface of the filter case. Therefore, the filter case and the filter element can be heated directly from heat generated by the fuel heater to effectively heat the fuel flowing therethrough, thereby preventing precipitation of a wax component that could clog the filter element. Also, fuel supply passages for supplying the fuel to the filter element are formed along the side surface of the filter case. Therefore, the fuel is brought into sufficient contact with the filter case heated by the fuel heater, thereby effectively heating the fuel.
