A quick connect coupling having a female part with a throughbore for receiving a tube having an annular extending bead. A latch is supported in the female part in communication with the throughbore. A verifier is provided in stacked arrangement with the latch. Insertion of the tube results in extending sides of the latch expanding outwardly and likewise expanding the extending sides of the verifier. Upon passage of the bead past the latch, the latch seating in the engaged position, with the verifier held open by alignment with the annular bead. The verifier subsequently being displaced to a fully engaged position to indicate that the fluid coupling is fluidly and fully connected.

A liquid tank having a tank interior space delimited by a tank wall and fillable with liquid, a withdrawal opening; a retention component that delimits a component interior region in the tank interior space; the component volume of the interior region being less than the tank volume; a partition of the retention component permitting a flow of liquid, out of a component exterior region located outside the interior region but inside the tank volume, through the partition into the interior region and presenting a flow resistance to a flow out of the interior region through the partition into the exterior region, in such a way that the partition exhibits a liquid retention capability with respect to surging movements of liquid in the interior region; the withdrawal opening being arranged in such a way that at least as soon as a level falls below a threshold, the partition is arranged between the withdrawal opening and a liquid quantity received in an exterior region of the tank interior space; the retention component is flowthrough-capable at least in portions only unidirectionally from the exterior region into the interior region, but not in the opposite direction.

A pump unit includes an insertion guide member that extends in a longitudinal direction of the pump unit and is used to guide the pump unit at a time of inserting the pump unit into an opening portion of a fuel tank. The insertion guide member includes a stopper portion and a guide portion that are arranged along an edge part of the insertion guide member. When the pump unit is projected in the longitudinal direction onto a plane of projection, the stopper portion protrudes outward from an imaginary circle, which has a fitting portion's diameter, on the plane of projection. The guide portion guides the pump unit in a rotational direction relative to a stay. A cross section of the pump unit taken along a guide portion orthogonal plane is set to be within the imaginary circle, which has the fitting portion's diameter.

The invention relates to a filler pipe (1) weldable to a liquid tank (3) of a vehicle, wherein the filler pipe comprises a main body (4), a secondary body (5) configured to support an inlet check valve (2) and a weldable flange (6) suitable for welding around an opening in the liquid tank (3), the weldable flange (6) extending between the main body (4) and the secondary body (5).

A primary metal terminal connects between a fuel pump and a drive circuit through a resin lid. A primary connecting point of the primary metal terminal connected to the drive circuit, is positioned around a drive control IC, and a primary exposed portion of the primary metal terminal, exposed to a receiving space of the resin lid is bent such that the primary exposed portion is resiliently deformable. A secondary metal terminal connects between an external circuit system and the drive circuit through the resin lid. A secondary connecting point of the secondary metal terminal connected to the drive circuit is positioned at a location that is further spaced from the drive control IC in comparison to the primary connecting point, and a secondary exposed portion of the secondary metal terminal exposed to the receiving space has a stiffness higher than a stiffness of the primary exposed portion.

A fuel pump includes: an electric motor; a pump stage drivable by the electric motor; a fuel pump housing configured to accommodate the electric motor and the pump stage; and a bracket configured to fasten the fuel pump to a wall. The fuel pump housing includes a plastic first housing part configured to accommodate at least one selected from the group of the electric motor and the pump stage. The first housing part is configured as a single piece with the bracket, the bracket being integral with the first housing part.

A method of forming a tank with a stiffening assembly includes forming a fuel tank such that the tank wall carries at least a first and second insert, locating a connecting assembly within the tank interior aligned with the first and second inserts, the connecting assembly including a tubular body, a first coupler, and a second coupler, and coupling at least a portion of the first insert with the first coupler and at least a portion of the second insert with the second coupler to limit movement of the two wall portions relative to each other.

A tank assembly and a stiffening assembly include first and second inserts and an elongate coupler. The inserts comprise a base having flange, a head, and a neck. The elongate body has first and second couplers at respective first and second ends of the body, each coupler including a pocket sized to receive the head of a respective one of the inserts. The related method include forming a fuel tank such that the tank wall carries at least a first and second insert, locating a rigid connector within the tank interior aligned with the first and second inserts, the connector including a first coupler and a second coupler, and coupling at least a portion of the first insert with the first coupler and at least a portion of the second insert with the second coupler to limit movement of the two wall portions relative to each other.

A coupling stay includes a support inner peripheral surface extending along a rotational axis and providing radial support to a rotatable shaft portion of a pump unit, which extends along the rotational axis. A support lateral surface extends in a longitudinal direction and provides thrust support to the pump unit. The support inner peripheral surface extends from the support lateral surface in the transverse direction. A lock claw projects from the coupling stay. A lock projection projects from the pump unit and is operable to lock rotation of the pump unit relative to the coupling stay about the rotational axis upon fitting of the lock projection between the support lateral surface and the lock claw. A height of a contact part of the lock projection, which contacts the support lateral surface, is limited to be equal to or lower than the rotational axis.

A fuel tank and a method for producing a fuel tank for a motor vehicle. The fuel tank is designed as a blow-molded hollow plastic member, into the interior of which a functional component support is introduced. The support, to which functional components, such as a fuel pump, a level indicator or valves can be secured, includes at least one supporting leg to be supported on an inner face of the hollow plastic member delimiting the interior thereof. The supporting leg of the functional component support is designed to include a connection point to which a functional component can be connected.
