In one embodiment, a system for installing and sealing a fuel pump in a fuel tank may include (1) a fuel tank with an opening in a surface thereof; and (2) a fuel pump hanger assembly, the fuel pump hanger assembly comprising; (a) a plurality of assembly screws; (b) a plurality of clamping lugs configured to thread onto the plurality of assembly screws and engage an inside surface of the fuel tank; (c) a top plate further comprising; (i) a bearing surface configured to engage an external fuel tank surface; (ii) a plurality of through holes proximate the perimeter of the top plate and perpendicular to the bearing surface; (iii) a plurality of bosses, each of the plurality of bosses adjacent to each through hole, configured to guide and position the each clamping lug; and (d) a gasket positioned between the top plate and the fuel tank.

A fuel pump assembly includes an attachment section and a pump housing. The attachment section includes an upper telescoping section having an outer portion and a support rod that extends into the outer portion for telescoping movement with respect thereto. The support rod further extends downward from the outer portion. The pump housing is supported to a lower end of the support rod of the attachment section. The upper telescoping section of the support rod is configured such that the pump housing is movable between a first position and a second position, such that in the first position the pump housing is retained by the upper telescoping structure a first distance away from the attachment section and in the second position the pump housing is located a second distance away from the attachment section. The first distance is greater than the second distance.

A fuel sender assembly having a housing, a first positioning mechanism, a second positioning mechanism and a sender unit. The first positioning mechanism contacts an outer surface of the housing and is movable in a first direction relative to the housing. The first positioning mechanism is further configured to retain the sender unit in any one of a plurality of positions relative to the outer surface of the housing. The second positioning mechanism includes a first part and a second part. The first part is attached to the first positioning mechanism. The second part is coupled to the first part such that the second part is movably positionable relative to the first part in a second direction perpendicular to the first direction. The sender unit is connected to the second part.

The invention concerns a process for the production of a container, in particular a fuel tank of thermoplastic material, by extrusion blow molding, wherein during shaping of the container within a multi-part tool the container is provided with at least one connecting element passing through the wall thereof, wherein with at least a part of the connecting element as a lost shaping male die the wall of the container is displaced from one side into a tool placed on the oppositely side of the container wall and removed. The invention further concerns a fuel tank with at least one connecting element which is connected to the tank wall at least in region-wise manner by intimate joining of the materials involved.

The present invention discloses an improved operating fluid reservoir having a venting and/or air admission valve. The operating fluid reservoir is characterized in that a valve housing is formed integrally with an operating fluid reservoir wall. A vent opening, via which a valve housing interior is in fluid communication with a vent line, is embodied as a through opening through the operating fluid reservoir wall. A valve body, which is arranged in the valve housing interior, can be introduced into the valve housing interior via an introduction opening in the valve housing. The valve body comprises a holding device, by means of which the valve body is held movably in the valve housing.

A fuel filler adapter has a hollow body having a base end with a flange extending outwardly therefrom, and a forward end, and has a length of between 0.5 inch and 2.5 inches. A bore extends through the body at an angle of between 2.5 and 15 so that the adapter can be fitted onto a fuel nozzle. Fueling spitback is prevented by a helical fuel path which does not block air from venting from a fuel tank. Air venting from the fuel tank exits through the fuel filler adapter via one or more venting channels.

The present invention discloses an improved operating fluid reservoir (1) having a venting and/or air admission valve. The operating fluid reservoir (1) is characterized in that a valve housing (10) is formed integrally with an operating fluid reservoir wall (2). A vent opening (3), via which a valve housing interior (11) is in fluid communication with a vent line (5), is embodied as a through opening (3) through the operating fluid reservoir wall (2). A valve body (20), which is arranged in the valve housing interior (11), can be introduced into the valve housing interior (11) via an introduction opening (16) in the valve housing (10). The valve body (20) comprises a holding device (23; 14, 24), by means of which the valve body (20) is held movably in the valve housing (10).

An inbuilt component fixing structure of a resin tank includes: a fastening seat that is provided to the inbuilt component, that is formed with a through-hole configured to fasten and fix the inbuilt component to the resin tank, and that has a contact face that contacts an inner face of the resin tank; a fixing section that projects out from the inner face and pierces through the through-hole, the fastening seat being fastened and fixed by being sandwiched between a jutting-out portion formed at a portion of the fixing section that has pierced through the through-hole, the jutting-out portion jutting out to a peripheral portion of the through-hole; and a weak portion that is formed at the fastening seat, that is thinner than a general portion of the fastening seat, and that has a lower rigidity in a removal direction of the fastening seat than the fixing section.

The invention relates to a container (1) of thermoplastic material with at least one support (4), which is arranged in the interior of the container, extends between opposing container walls (2) and is anchored at each end to the container walls with a positive engagement and/or a material bond, the support (4) comprising at least one supporting strut (5) and the supporting strut (5) substantially absorbing a supporting load on the container walls (2) induced by negative pressure in the container, and a tensile force that is induced by positive pressure being absorbed by at least one tension-resistant bracing element in the form of a tension-resistant band (8) which extends between the container walls (2).
