A fuel tank system includes: a fuel tank capable of storing fuel; a canister that has a ventilation port and an introduction port and that accommodates an adsorbent capable of adsorbing evaporative fuel introduced into the canister; a housing attached to the canister, and accommodating a pump configured to apply a pressure to an interior of the canister through the ventilation port; a pipeline that has an atmosphere opening port opening to an outside, the pipeline extending from the atmosphere opening port toward the ventilation port; and a filter unit having an internal space in which an air filter is arranged, the filter unit being removably fitted to the housing and the pipeline, the housing and the pipeline communicating with each other via the internal space.

A tank assembly for a motor vehicle includes an axially extending compressed gas tank having a middle portion and axially terminal end portions, and a tank support configured to fasten the compressed gas tank to a vehicle body. The tank assembly has a guard device that catches the compressed gas tank in the event the tank and/or support become partially or fully detached from the vehicle. A guard support is configured to secure the guard device to the vehicle body. A retaining element forms an axial stop for a first end portion, and at least one pliable tension element, which extends axially and connects the retaining element to the guard support in a tension-transmitting manner.

One embodiment of a molded fuel tank includes a fuel tank molded from a synthetic material, such as a composite polymer. One embodiment may include molding a fuel tank with metal component fastening structures positioned within the fuel tank as it is molded. One embodiment may include molding a fuel tank and integral component fastening structures simultaneously from synthetic materials. One embodiment of a molded fuel tank may include a fuel tank formed by a rotational molding process.

A seal structure includes: a tubular protrusion communicating with an inside of a resin tank body and projecting from the tank body; a mouth member being fixed along an inner peripheral surface of the protrusion; a lid member including a second tubular portion inserted from one end into the mouth member, a flange portion covering the other end of the second tubular portion, and a third tubular portion extending toward the insertion direction of the second tubular portion; a supporting surface provided to an outer peripheral side of the protrusion or the fuel tank body; and a ring-shaped sealing member supported on the ring-shaped shoulder surface and held between an outer peripheral surface of the protrusion and an inner peripheral surface of the third tubular portion in a state where the lid member is attached to the mouth member.

A method for producing a plastic container from a first plastic half-shell and a second plastic half-shell, with a first attachment permanently fastened to the first plastic half-shell.

A servicable draw and return tube assembly for use in fuel tanks is disclosed. The assembly may include a draw tube and a return tube secured to a plate, wherein the plate may be removably secured to a flange, which is fixedly secured to a fuel tank. The process of removably securing the plate to the flange allows for use of different sizes and materials to be utilized in manufacture of the assembly, thereby saving installation time and manufacturing costs.

The inside wall of a fuel tank, and a sub-component are provided with locking means in the form of complementary formations that allow the sub-component to be coupled to the inside surface of the fuel tank wall. Interlocking of the complementary formations is achieved by moving the sub-component towards the wall providing angular movement to the sub-component relative to the fuel tank. A biasing structure imparts a tension between the sub-component and the fuel tank.

Provided is a fuel tank for a vehicle in which a fuel measure bar provided in a vertical direction in a fuel storing body in which a fuel combusted in an engine is stored and capable of measuring a fuel amount using an ultrasonic wave includes a first fuel measure bar fixed to a bottom surface of the fuel storing body and a second fuel measuring bar easily coupled to the first fuel measuring bar to easily enter the fuel storing body and exit from the fuel storing body.

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.

Methods and systems are provided for a fuel tank mounted to a vehicle. Specifically, a saddle fuel tank comprising of a primary and secondary fuel compartment, each compartment having a module for mounting a fuel pump, fuel sensor and other accessories is disclosed. A first and second crimped opening formed on a top external wall and bottom internal wall, respectively of the saddle fuel tank may provide means for securely mounting a main and sub-side module to the fuel tank.
