A fuel supply device includes a pump unit, a lid unit and a strut linking unit. The pump unit is located on a bottom of a fuel tank for discharging fuel from the fuel tank to an outside thereof. The lid unit is attached to an upper wall of the fuel tank to close an opening formed in the upper wall. The lid unit has a fuel discharge port. The strut linking unit connects the lid unit to the pump unit. The strut linking unit includes an upper-side strut member, which is formed as an independent component from the lid unit. The strut linking unit includes a lower-side strut member, which is movably connected to the upper-side strut member in a vertical direction. The upper-side strut member is connected to the lid unit by a snap-fit connection. A connecting portion between the upper-side strut member and the lid unit has a stress concentration portion, which is preferentially damaged when an external force is applied to the strut linking unit.

When a fuel tank is inclined at a negative slope and tilted to the right side, it may be tilted such that a position of a mesh member is relatively higher than a position of a vapor outlet of a vapor outlet passage. In this case, air may enter into a leak passage from an outlet port such that interfacial tension is generated in the mesh member. The interface between fuel and air is present at the mesh member, and the interfacial tension generated at the interface serves to prevent air from entering into a discharge pipe.

A fuel supply device includes a fuel tank having an opening, a lid member closing the opening, a ring member holding an outer periphery of the lid member between the fuel tank and the ring member, an electrical component disposed within the fuel tank, and a contoller configured to control the electrical component and mounted on the ring member.

A fuel supply device includes a fuel pump, a pump case, a cap, an O-ring, and a connection assembly. The pump case includes a case main body configured to receive the fuel pump and a discharge port connector. The cap includes a suction port connector. The O-ring is interposed between a fuel discharge port of the fuel pump and discharge port connector. The connection assembly includes a plurality of engagement projections and a plurality of engagement pieces configured to mate and engage with the engagement projections. The fuel discharge port of the fuel pump is configured to reach the O-ring coupled to the discharge port connector of the pump case simultaneous with the engagement between the engagement projections and the engagement pieces when the fuel suction port of the fuel pump and the suction port connector of the cap are connected together.

A fuel tank cover (150) is provided with a flange unit (22) closing an opening of a fuel tank, and a joint member (24) configured to be connected to the flange unit (22) movably in the upward/downward direction. The flange unit (22) includes a side tubular portion (43) extending in the upward/downward direction. The joint member (24) includes a columnar portion (160) extending in the upward/downward direction. The columnar portion (160) is inserted into the side tubular portion (43) movably in the upward/downward direction. A metal retainer (162) is provided to cover an outer circumferential surface of the columnar portion (160).

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.

Provided are a controller integrated type fuel pump module for preventing thermal deformation of a flange and a manufacturing method thereof. An embodiment of the present invention is directed to providing a controller integrated type fuel pump module for preventing thermal deformation of a flange that minimizes heat transfer from a board to the flange through a thermal insulation effect by an air gap by improving a structure in a storage part of a controller to form the air gap between the board and the flange in the controller formed integrally with a fuel pump module, and a manufacturing method thereof.

A fuel ejector assembly for a vehicle. A second fluid passage extends into a first fluid passage so that a nozzle opening is arranged inside the first fluid passage facing an outlet flow port such that a first flow of fuel in the first fluid passage flows around the nozzle opening. A flow shape unit is disposed within the first fluid passage in connection to the nozzle opening.

A sender assembly that has a compact state, which may allow a pump assembly including the sender assembly to be easily inserted into an opening of a fluid tank. For example, the pump assembly may be insertable into the opening of the fluid tank while a longitudinal axis of the pump assembly remains coaxial with the opening. When in the compact state a rotatable arm and a float of the sender assembly may be entirely within or deformable to be within a predetermined envelope that has a radial extent less than the opening of the fluid tank to allow the sender assembly to be inserted straight into the opening. The predetermined envelope may be coaxial with the longitudinal axis and have a cross-section transverse to the longitudinal axis that matches the opening of the tank.

A flange main body as a cover member for a fuel tank includes a cover plate for closing an opening of the fuel tank, an accommodating tubular portion formed as part of the cover plate so as to extend through the plate in a plate thickness direction, and a rib formed at the cover plate. The accommodating tubular portion and the rib are formed to be non-contiguous.
