Systems are provided for refueling a fuel tank of a motor vehicle via an insert for a filler pipe. In one example, a system may include an insert coupled to an inner circumference of the filler pipe, the insert including a plurality of projections positioned on an inner circumference of the insert. The plurality of projections may include a first projection spanning a first axial length, a second projection spanning a second axial length, and a third projection spanning a third axial length.

Disclosed is an inlet end piece for the tank inlet of a motor vehicle, having a closure insert arranged in an upper area of a pipe inlet, having a filling opening and a sealing flap which counter to the force of a closure spring by way of a gas pump nozzle is capable of being opened by pivoting, and is held in the closed state by the closure spring. The inlet end piece has an indicator means having an indicator area, wherein the indicator means in the case of a closed sealing flap is located in an inactive position in which an indicator area of the indicator means is not visible to the user, and in the case of the sealing flap being at least partially opened, the indicator means is displaced into a signal position in which the indicator area becomes visible.

A fuel supply apparatus for supplying fuel to a fuel tank, includes: a flow path forming member configured to form a fuel flow path; and an injection port forming member, arranged in the fuel flow path, configured to form an injection port into which a fueling nozzle, configured to discharge the fuel, is inserted, wherein at least one of the flow path forming member and the injection port forming member includes an impact absorbing part to be contacted with the other and configured to absorb an impact to be produced by the fueling nozzle when the fueling nozzle comes into contact with the injection port forming member.

To prevent fuel from leaking to outside even when the fuel flows back at the time of an automatic stop operation during refueling. A fuel supply portion structure of a fuel supply pipe, including a tubular portion having a filler port and a connection port, a first flap mechanism which is provided on the filler port side of the tubular portion, a drain hole, and a drain hole on-off valve, wherein the drain hole on-off valve is disposed on a placement surface located at the lowermost side of a vehicle on an inner wall of a first inner diameter member, the placement surface is made of an inclined surface falling from the filler port side toward the connection port with respect to a horizontal plane of the vehicle, and a wall portion rising toward the filler port is provided on the filler port side of the inclined surface.

An assembly according to the present disclosure includes a bezel having a first aperture therethrough. The bezel has a first face and a second face. The second face is provided with a plurality of retention loops. The assembly includes an elongate member disposed at least partially within the first aperture. The elongate member is generally fixedly positioned relative to the bezel. The assembly further includes a movable closeout feature having a second aperture therethrough. The elongate member is disposed at least partially within the second aperture. The movable closeout feature is provided with a plurality of tabs. Respective tabs of the plurality of tabs are disposed in corresponding respective loops of the plurality of retention loops. The movable closeout feature is repositionable relative to the bezel by contact with the elongate member.

A filler tube for a fuel tank, having a tube portion made of plastic material and a tubular adapter, which is connected to the tube portion, for coupling the filler tube to the fuel tank, wherein a lateral surface of the adapter is integrally bonded, in particular welded, to a lateral surface of the tube portion, wherein the adapter and the tube portion overlap in the region of the integrally bonded connection.

A fuel supply device (FS) includes a filler neck (10) that includes a nozzle guiding path that guides a fuel supply nozzle (FN), and a fuel passage that is continuous to the nozzle guiding path on a downstream side of the fuel passage, through which fuel that has been discharged from the fuel supply nozzle (FN) passes; a fuel vapor port (23) located outside of the filler neck (10) that has a through hole (23H) that communicates with the fuel passage (11Pd); and a vapor introduction body (70) that guides the fuel vapor from the fuel vapor port to the fuel passage (11Pd). The vapor introduction body (70) includes a within-through-hole support (71) that is inserted into and held in the through hole (23H), and includes a vapor passage (71a) along the through hole (23H), and a changing member (72) that faces an opening of the vapor passage (71a) on a side of the fuel passage (11Pd), and is configured to change a direction of flow of the fuel vapor that passes through the vapor passage (71a) to the side of the fuel passage (71a). The vicinity of the fuel vapor port in the filler neck is configured compactly.

Disclosed herein is an integrated fuel mixing prevention device for a diesel vehicle, in which a diesel filler neck and a urea filler neck are integrated with each other to prevent fuel from mixing, allowing only a diesel fuel filling gun to be inserted into a fuel inlet when a diesel fuel filling mode is selected and allowing only a urea filling gun to be inserted into the fuel inlet when a urea filling mode is selected, which may prevent a fuel mixing an accident caused by incorrect replenishment.

The fuel supply device comprises a filler neck provided to include a fuel supply port which a fueling gun is inserted in and configured to form part of a fuel passage from the fuel supply port to a fuel tank, a fuel vapor pipe connected with the fuel tank and with a fuel vapor port and configured to supply a fuel vapor in the fuel tank to an internal passage of the filler neck main body, and a buffer member at least partly placed between a filler neck main body and the fuel vapor port in a neighborhood of a branch portion where the fuel vapor port is branched off from the filler neck main body. The filler neck comprises the filler neck main body including the internal passage and the fuel vapor port branched off from the filler neck main body.

An adapter is provided for securing a filling tube of a fuel container to a body of a motor vehicle. The adapter has a contact region for placement on the body and a first securing point for securing a first holder for the filling tube. This allows for it to be easily adapted to different vehicle body shapes.
