A fuel tank made of a resin includes: a tank body having walls facing each other therein; and an internal strut including both ends fixed to the facing walls respectively. The internal strut has a grid shape such that through holes are arranged as viewed from a side.

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.

The present invention relates to a flange that includes a base region, a first raised region, a second raised region, a first sloped region between the base region and the first raised region, and a second sloped region between the base region and the second raised regions, wherein the first and second sloped regions extend through a gap region between the first and second raised regions, and wherein the first and second sloped regions define multiple concave and convex regions in multiple planes of the flange so as to reduce stress within the flange.

A stiffness reinforcement structure for a fuel tank of a vehicle includes: a reinforcing column having an upper opening and a lower opening, and side openings arranged at both sides of an upper end and both sides of a lower end thereof; sliders fastened to the side openings of the reinforcing column; an upper thermal bonding member inserted in the upper opening and fastened to corresponding sliders; a lower thermal bonding member inserted in the lower opening of the reinforcing column and fastened to corresponding sliders with a bottom thermally bonded to an inner side of the fuel tank; and springs wound around outer sides of the reinforcing column and the sliders and providing elastic compression force to the upper thermal bonding member and the lower thermal bonding member.

A fuel feed module for delivering fuel from a fuel tank includes a fuel feed pump and a flange. The fuel feed module is fixable to the fuel tank by the flange. The fuel feed module includes a resistor, which is electrically conductively integrated into a ground path of the fuel feed pump, the resistor being integrated into the flange of the fuel feed module.

A capless filler pipe closure is provided for a tank filler pipe. The capless closure permits a fuel pump nozzle to be inserted into the tank filler pipe without first removing a fuel cap from the outer end of the tank filler pipe.

The present invention relates to an integrated fuel tank assembly, and a process of manufacturing the same, for use in commercial vehicles, and more particularly, to an integrated fuel tank assembly that allows multiple components to be manufactured as a single integral structure, such as a single extruded device including a draw tube, a return tube, a fuel sender device, and a vent, for example.

An in-tank fuel pump assembly and mounting system is disclosed which may be configured for mounting inside a fuel tank. The assembly includes a pump housing, pump mounted to the housing, and pressure relief valve. The housing may comprise upper and lower pump housing units coupled together. The upper housing unit is configured for mounting to a tank opening, which in one implementation may be the fuel fill opening. The lower housing unit extends into the tank to approximately the bottom of the tank. A fuel fill fluid pathway is created through the housing for adding fuel to the tank while the pump assembly remains in situ. The upper housing unit may include a removable fuel cap. The pump housing may include an integral vapor trap.
