ABSTRACT:
A filter device for a fuel tank includes a suction pump main body contained within a fuel tank, a generally cylindrical mounting member mounted upon a bottom portion of the pump main body, and a filter attached to the bottom portion of the pump main body through means of the mounting member. The filter comprises a net. The net is folded over upon itself such that an upper net piece and a lower net piece are vertically overlapped with respect to each other. The upper net piece is formed with a through hole for permitting an upper portion of the mounting member to pass therethrough. The peripheral portions of the net pieces are welded to each other so that the filter is formed as a flat, bag-shaped structure defining an inner enclosed space. The upper portion of the mounting member is connected with the bottom portion of the pump main after passing through the through hole. The inner enclosed space of the filter is in fluid communication with the pump main body by means of the mounting member.
