Abstract

See full text

A filter for an in-tank type fuel pump. The filter comprises a frame, a bag type screen adapted to be kept in an expanded condition by the frame, and a flat protector to be interposed between the screen and a bottom surface of the fuel tank. The protector is attached to the screen substantially at the central portion of the protector in the longitudinal direction thereof, so that it may be pressed against the tank bottom surface by a small deflecting force of the screen. This construction is effective to cause less transmission of noise of the pump to the tank.
