A cover for a fuel tank includes a flange unit configured to close an opening of the fuel tank and a joint member movably coupled to the flange unit. The joint member is configured to move in an upward/downward direction relative to the flange unit. Two side tubular portions extend from the flange unit in the upward/downward direction and are positioned side-by-side. Column portions extend in the upward/downward direction from the joint member. The column portions are moveably disposed in the side tubular portions. The column portions are configured to move in the upward/downward direction relative to the side tubular portions. The side tubular portions are connected to each other via a rear side wall and a front side wall of a center tubular portion disposed between the side tubular portions.

Cover for fuel tank

A fuel supply device includes a fuel supply passage, a fuel pump, a pressure-regulating valve, and a housing. The fuel supply passage is in communication with the fuel injector. The fuel pump pumps the fuel to the fuel supply passage. The pressure-regulating valve regulates the pressure of the fuel in the fuel supply passage. The housing is disposed in the fuel tank. The housing accommodates the fuel pump and the pressure-regulating valve. The fuel supply passage is formed within the housing. The pressure-regulating valve is connected to an end portion of the fuel supply passage formed in the housing. The volume of the end portion of the fuel supply passage in the housing is configured to increase with increasing pressure of the fuel.

Fuel supply device

A sender gauge adaptor includes an adaptor body pressed against a bottom wall of a fuel tank by a spring. The adaptor body includes a suction inlet part having a hollow cylindrical shape that opens downward. Recesses allowing fluid communication between the interior and the exterior of the suction inlet part and projection parts having a polygonal-shaped lower surfaces are alternately arranged in the circumferential direction along a lower end of the suction opening. The adaptor body includes a seat part in surface contact with the bottom wall of the fuel tank at a position below the lower surfaces of the projection parts.

Fuel suction inlet member

A cover for a fuel tank includes a flange unit configured to close an opening of the fuel tank and a joint member connected to the flange unit. The joint member is movable in an upward/downward direction. The flange unit includes a side tubular portion extending in the upward/downward direction. The joint member includes a support column portion extending in the upward/downward direction. The support column portion is movably disposed in the side tubular portion so as to be movable in the upward/downward direction. The support column portion is connected to the side tubular portion by a snap-fit so as to be movable and suspendable in the upward/downward direction.
