To protect a pipe and the like without changing the shape of a flange, by forming of a synthetic resin, a fuel pump, a cover plate and the connecting opening of a fuel pipe and the like, and also arranging the upper surface of a coupler in a position higher than the fuel pipe.

The connecting opening 12 of a fuel pipe formed of a synthetic resin, the connecting opening 11 of a return pipe, the connecting opening 10 of an evaporator hose, the connecting opening 9 of a breather hose, and the coupler 13 of an electric connector formed of a synthetic resin, are arranged on the upper surface of a cover plate 7, and the fuel pipe and the like is connected to the connecting opening 12 and the like. A harness 14 is connected to the coupler 13, data of height of a liquid level detected by the control circuit of a motor to drive a fuel pump and the height of a float, is connected to a control circuit, and many members are arranged on the upper part of the cover plate 7 however, the coupler 13 is arranged highest. Hereby, the fuel pipe and the like may not be collided with a metallic panel on a car body side by vibration when an automobile is traveled, and a pipe and the like can be protected.
