Abstract:

To provide a fuel filter device that has a simplified structure for informing of the clogging of a filter material.

The fuel filter device is configured such that a diaphragm pump device 60 is disposed downstream of a filter 24, and, when the clogging of the filter material 24 has progressed to bring the fuel pressure downstream of the filter material 24 to a certain high pressure that may cause any defect or failure, a nob 65 deforms downward to indicate that the clogging of the filter material 24 has already progressed to a condition that is about to cause any defect or failure.
