Abstract: A fuel filter is disclosed herein, comprising: a cup-shaped conductive housing with an opening on one end; a lid, provided at the opening end of the cup-shaped conductive housing to cover the opening, the cup-shaped conductive housing and the lid together defining a fuel filter cavity; and a heater, provided inside the fuel filter cavity, configured to heat fuel inside the fuel filter cavity; wherein the heater includes a grounding electrode that is electrically connected to the cup-shaped conductive housing. The fuel filter as described above electrically connects the conductive housing and the grounding electrode of the heater, creating a connecting path that grounds the conductive housing without need of a separate grounding lead. Therefore, a more compact structure and lower costs are made possible.
