Therefore, in the state shown in the figure where there is almost no water in the water reservoir A, the flow (10) is located at the lower position and the reed switch 9 is off, but water gradually accumulates. When the float 10 rises little by little and the water surface reaches approximately two-thirds of the height of the water reservoir A, the magnet 11 inside the float turns on the reed switch 9 inside the guide rod 8. It has become.

As described above, the fuel filter according to this invention is equipped with a water reservoir at the bottom of the filter, and a mounting hole is formed at the lower end of the water reservoir, and a reservoir water amount detector and a drain plug are attached to this mounting hole. Since the bolt-shaped boss is screwed on, the structure of the water reservoir body is simpler than conventional ones, and the accumulated water amount detector and drain plug can be installed simply by screwing on the boss. Therefore, machining and assembly work are facilitated, and maintenance is also extremely easy because the accumulated water amount detector and the drain can be easily inspected by removing only the boss from the water reservoir.
