A tank shell for a motor vehicle tank, exhibiting a tank shell inner surface facing towards the tank volume surrounded by it and a tank shell outer surface facing away from the tank volume surrounded by it, where a tank shell wall exhibits at least section-wise a multilayer layer structure, where the layer structure having at least one interior wall section produced by injection molding and located nearer to the tank shell inner surface, at least one exterior wall section produced by injection molding and located nearer to the tank shell outer surface, and a barrier film located between the interior wall section and the exterior wall section, where the tank shell wall exhibits at least one aperture penetrating through the tank shell wall along an aperture path, where a section of the barrier film is exposed in the region of the aperture; the section of the barrier film exposed in the region of the aperture is configured integrally with the barrier film in the tank shell wall and for contacting by a sealing arrangement of a conduit component realized separately from the tank shell wall.

A fuel pump cover assembly and method for a vehicle includes a cover arranged over the vehicle fuel pump for inhibiting water access to the vehicle fuel pump and at least one clip securing the cover to a feed line for the vehicle fuel pump.

A diesel exhaust fluid (DEF) cap assembly for a vehicle includes: a body having a first opening and a second opening arranged at an opposite side of the first opening, the second opening configured to be opened and closed; a flange portion protruding radially outward between the first opening and the second opening of the body, and having a plurality of through holes and a flange gasket configured to be sealably coupled to a mounting subject on which the flange portion is mounted; and a membrane member coupled to the flange portion, and configured to cover the plurality through holes and allow air flow.

A fuel tank valve apparatus includes a valve port configured to allow inside and outside of a fuel tank to communicate with each other, a valve chamber formed under the valve port, a float body disposed movably up and down inside the valve chamber, and a seal member having elasticity with respect to the valve port and mounted on an upper portion of the float body. The seal member includes a main body configured to close the valve port, a combining portion with respect to the upper portion of the float body, and an extending portion laterally extending from the main body. The float body includes a combined portion combined with the combining portion with up-and-down movements of the seal member allowed in a predetermined range, and a hook portion located above the extending portion.

A system for a motor vehicle, the system including a container having a side made of a plastic material, and a component sealingly attached to the container side. The component has at least one portion provided with microgrooves that form a sealing area between the component and the container side.

A fabric and elastomeric material (referred to as a fabric trilayer) combined with a sealant may be applied in such a fashion so as to eliminate or minimize air entrapment in an elastomeric composite structure that forms a seal-sealing volume. The performance of the self-sealing volume is dramatically improved with this minimizing of air entrapment. Surprisingly and unexpectedly, this construction approach may be accomplished without significantly adding to the weight or thickness of the volume and without affecting the outer dimension of the self-sealing volume. Thus, a method and system for forming a self-sealing volume are described. The system includes an elastomeric composite structure comprising at least one layer of an elastomeric material derived from a neat (no solvent) elastomeric material that does not substantially react at room temperature.

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.

A fuel tank for a generator or the like, wherein the fuel tank includes a rigid outer fuel tank structure and an inner bladder. The outer fuel tank structure includes a longitudinal channel for receiving the inner bladder. End caps are disposed on either end of the outer fuel tank structure, so that the internal bladder may be pulled therein with cables or the like. When the internal bladder needs to be replaced due to damage or corrosion, the end caps are removed and cables may be attached to one end of the damaged internal bladder for pulling it from the outer fuel tank structure. Additionally, a replacement bladder may be attached via cables to the other end of the damaged bladder, so that the replacement bladder is pulled into one end of the outer fuel tank structure while the damaged bladder is being pulled out the other end thereof.

Power machine fuel tanks include a plug receptacle and a cover for the plug receptacle which seals the plug receptacle from an interior of the fuel tank. A receptacle insert positioned within the plug receptacle allows a fuel plug to be removably secured to the fuel tank. The cover prevents leakage from inside the fuel tank through the plug receptacle, regardless of whether the plug is secured within the receptacle insert, unless the cover has been removed from a sealing position.

A liquid vehicle tank (1) having a wall made of a plastic material, the tank (1) comprising a component (3, 5) affixed to the wall, the component (3, 5) having a portion (10) embedded in the wall, the embedded portion (10) having an external surface (21) a part of which is chemically incompatible with the plastic material of the wall, wherein the tank (1) also comprises a strengthening element welded to the wall over the embedded portion (10) of the component (3, 5).
