A tank mounting adapter is provided that includes a tank adapter disc and a compression nut. The tank adapter disc includes an opening disposed therethrough, which may be sized to receive at least a portion of the support structure of the fluid pump. The compression nut may include a collar with a threaded opening disposed therethrough such that threads of the threaded opening are configured to correspond to threads on the support structure of the fluid pump. The compression nut may be located adjacent the tank adapter disc. The collar may further include a lower portion that extends into the opening of the tank adapter disc. The compression nut may be movable with respect to the tank adapter disc and against the tank adapter disc.

There is provided a valve device, including: a housing in which, via a partition wall, a valve chamber is provided below the partition wall and a vent chamber is provided above the partition wall, and a vent hole through which the valve chamber and the vent chamber communicate with each other is provided in the partition wall; and a float valve. A valve seat is formed on a side of the valve chamber of the partition wall, and an opening is provided on an inner side of the valve seat. The opening includes a first opening and a second opening extending outward in a slit shape from an outer periphery of the first opening. A seal part having elasticity that contacts with and separates from the valve seat to close and open the first opening and the second opening, is disposed above the float valve.

A close-out assembly includes a housing and an inlet. The housing includes a wall that surrounds an opening. The wall includes an outer edge adjacent to the face plate and an inner edge. The inlet is coupled to the wall, and the inlet is accessible through the opening. The assembly includes a door coupled to the housing that is movable relative to the housing. The assembly includes a seal formed to the wall at the outer edge of the wall and the inner edge of the wall. The door engages one part of the seal when the door is in a closed position, and the inlet engages another part of the seal regardless of the position of the door. A method of manufacturing the assembly includes positioning a housing relative to a mold, and molding an elastomeric material to the housing using the mold to form a seal.

A retaining ring for securing a pump to a tank. The ring has a circular body with an outer dimension selected to surround a pump opening in the fuel tank. An interior opening has a diameter that is selected to contact a portion of a pump housing that is placed in the tank. The retaining ring is fastened or attached directly to the tank.

A tubular fuel filler pipe body is a blow molded body and is adapted to connect to a fuel tank at one end thereof. The fuel filler pipe body includes in an outer circumferential surface of another end side thereof an annular recessed groove. The fuel filler pipe body includes an opening of the other end thereof to which a nozzle guide is mounted. The nozzle guide includes on an one end side thereof an annular covering portion configured to cover annularly the outer circumferential surface of the other end side of the fuel filler pipe body. An annular rubber sealing member configured to seal between an inner circumferential surface of the annular recessed groove and an inner circumferential surface of the annular covering portion fits with the annular recessed groove.

A fuel tank vent valve includes a venting apparatus for regulating discharge of fuel vapor from a fuel tank and admission of outside air into a fuel tank. The vent valve is used to regulate pressure in a fuel tank.

A plastic tank for a motor vehicle. The plastic tank includes a container wall composed of plastic, an opening arranged in the container wall, a removable cover member operable to close and open the opening, and a stiffening ring member, composed of an injection-moulded plastic, embedded into an edge of the container wall that surrounds the opening, the stiffening ring member being operable to directly or indirectly support the cover member when the opening is closed.

The invention is related to a new-generation fuel tank connection in all kinds of military vehicles, which enables a space reserved for the fuel tank to be used more efficiently, by reducing mounting space required according to the conventional methods. The invention is especially related to a new-generation fuel tank connection which comprises a sealed gasket (60) which has connection holes (62) to attach connection pieces (30) on the tank, which is produced from the materials suitable with fuel, which serves as leaking and vibration damping between fuel tank and sealing element (20), which has a conicity (64) in its inner surface (63) for ease of mounting of the sealing element (20), and a sealing element (20) which connects to the support (120) located on the vehicle roof (130) through connection holes (23) with connection pieces (30) and of which part entering into (63) the sealed gasket (60) tightened with clamp (50) has a conical (22) structure.

A tubular fuel filler pipe body is a blow molded body and is adapted to connect to a fuel tank at one end thereof. The fuel filler pipe body includes in an outer circumferential surface of another end side thereof an annular recessed groove. The fuel filler pipe body includes an opening of the other end thereof to which a nozzle guide is mounted. The nozzle guide includes on an one end side thereof an annular covering portion configured to cover annularly the outer circumferential surface of the other end side of the fuel filler pipe body. An annular rubber sealing member configured to seal between an inner circumferential surface of the annular recessed groove and an inner circumferential surface of the annular covering portion fits with the annular recessed groove.

A fuel container having walls defining a space in which fuel is to be contained, a layer of deformable material bonded to the external surfaces of the container walls, and a self-sealing layer of fuel-activated swellable material bonded to the deformable material, wherein said self-sealing layer is a latex foam, in particular a natural rubber latex foam, comprising a non-ionic associative thickener as rheology modifier and optionally other additives such as foam enhancers, foam stabilizers, accelerators and vulcanization components.
