燃料フィルタ装置。A heater is attached to the inflow part to the filter provided in the fuel supply part of a diesel engine, and a detection means for detecting a change in the property of the fuel supply part based on the amount of deposited wax on the filter, and based on this detection means, the above-mentioned In a fuel filter device having a switch for opening and closing an energizing circuit to a fuel heater, a pressure sensor for detecting negative pressure is provided as the detection means at an outlet from the filter, and this pressure sensor detects negative pressure downstream of the filter. The command to close the switch is issued based on the amount of change that is greater than the set value, or based on the atmospheric pressure or the differential pressure that is greater than the set value with the upstream side of the filter, and the command to close the switch is issued based on the negative pressure or differential pressure that is less than the set value. A fuel filter device comprising a control circuit that issues a command to open a switch.
