ABSTRACT:
A fuel tank filter assembly for a vehicle is disclosed which includes a suction pipe and a filter connected through the pipe to an inlet port of a bottom plate for a fuel suction pump, and which is characterized in that the bottom plate is formed of resin material so as to be integral with the suction pipe. Also disclosed is a shape retaining frame of a box-like shape made of a resin and having downwardly extending protrusions. The frame includes a plurality of beams and the filter assembly includes a filter fabric formed into a bag which encapsulates the frame, a stopper member for engaging the protrusions upon downward deflection of the protrusions, and a suction pipe made of a resin, one end of the suction pipe being inserted into an insertion opening of the filter fabric and attached to the frame, the other end of the suction pipe being connected to an inlet port of a fuel suction pump outside the filter fabric, and which is characterized in that the peripheral portion of the insertion opening of the filter fabric for insertion of the suction pipe is interposed between an upper flange formed in the frame and has an opening for insertion of one end of the suction pipe and a flange formed on the suction piper correspondingly to the upper flange, and by the frame and the suction pipe being fusion-bonded together.
