An active drain liquid trap configured for use with a fuel tank system and constructed in accordance to one example of the present disclosure includes a trap body, a float and a pilot. The trap body defines a first inlet, a second inlet and an outlet. The first inlet is fluidly connected to a fuel pump. The second inlet is fluidly connected to a vapor line. The float is rotatably mounted about a float pivot. The pilot moves between an open and closed position. Rotation of the float causes the pilot to be urged into an open position and fluid to be drained from the trap body through the outlet.

An intake chamber (10) for an operating medium pump for sucking up operating medium stored in an operating medium tank of a motor vehicle, comprising a housing (20) in which at least two inlet openings (31, 32) for admitting operating medium to a connection (60) formed in the top side of the housing (20) are formed, wherein a deflecting wall (51, 52) is arranged in the housing (20) be-tween each inlet opening (31, 32) and the connection (60). Undercuts (81, 82) are formed on the inside of the inlet openings (31, 32). A suction jet pump or operating medium pump with at least one such intake chamber 10 is also disclosed.

A fuel tank includes a fuel tank main body portion, a first supporting pillar portion, and a second supporting pillar portion. The first supporting pillar portion is provided at a vehicle rear side of an inner side of the fuel tank main body portion. The second supporting pillar portion is provided at a vehicle front side of the first supporting pillar portion at the inner side of the fuel tank main body portion and is longer in the vehicle vertical direction than the first supporting pillar portion is in the vehicle vertical direction.

A fuel supply device includes: a cover attached to an upper wall of a fuel tank; a pump unit disposed on a bottom wall of the fuel tank; and a connecting strut that connects the cover and the pump unit with each other. The pump unit includes: a unit body supported by the connecting strut in a radial direction and a thrust direction, and a fuel pump arranged on the unit body to pump fuel drawn from the fuel tank toward an internal-combustion engine. The fuel pump is located offset toward the connecting strut from a width center of a width from a thrust support part where the unit body is supported by the connecting strut to an end part of the unit body opposite from the connecting strut in a specific transverse direction.

A vehicle includes a fuel tank, a jet pump and a controller. The fuel tank has a passive side and an active side. Each of the sides includes a fuel level indicator. The jet pump is disposed within the active side and is configured to maintain a fuel level above a first threshold, based on each of the indicators, on the active side by siphoning fuel from the passive side during operation in a combustion mode. The controller is configured to, in response a battery charge level being below a second threshold during operation in an electric mode and a detected hill climb via a route guidance system, activate the jet pump to siphon fuel such that a fuel level within the active side rises above the first threshold.

The present disclosure relates to a fuel tank having a module pot, which forms a first separate fuel reservoir for a fuel pump arranged inside the fuel tank. To prevent a gap in delivery of fuel to supply the first fuel reservoir in certain operating conditions, in particular when there is persistent lateral acceleration, according to the invention, a second separate fuel reservoir arranged separately from the first fuel reservoir inside the fuel tank is proposed, such that fuel is transferred from the second fuel reservoir into the first fuel reservoir at least when a predetermined acceleration level acting on the fuel tank is exceeded.

A fuel supply device has a module installed in a fuel tank. The module has a cap and a support pillar arranged between the cap and a bottom of the fuel tank. The support pillar supports a suction filter and a level sensor to use the bottom of the fuel tank as a base point for defining proper positions. The cap supports a valve relevant to ventilation of the fuel tank. The valve is supported by a base portion. The valve is positioned in the support pillar. The valve and the support pillar are arranged to overlap each other along the height direction. Various components are arranged in the small cap.

A fuel system includes a fuel pump and a jet pump assembly. The jet pump assembly includes a first fuel passage defined by a first tube. The jet pump assembly also includes a second fuel passage which receives pressurized fuel from the fuel pump, the second fuel passage having a primary orifice centered about and extending along a primary orifice axis such that the primary orifice axis is directed into the first fuel passage and such that the primary orifice introduces a first flow of fuel into the first fuel passage. The second fuel passage also has a secondary orifice centered about and extending along a secondary orifice axis which is not coincident with the primary orifice axis and which is directed at an inner surface of the first tube and the secondary orifice introduces a second flow of fuel into the first fuel passage which impinges the inner surface.

A fuel tank system is provided. In the main tank of the system, the end of a communication pipe is located above the end of a fuel introduction pipe inserted into the main tank. The end of a first pressure relief pipe at which a first cut-off valve is provided is located above the end of the communication pipe. In the auxiliary tank, the end of the communication pipe is located above the end of the fuel introduction pipe inserted into the auxiliary tank. In the auxiliary tank, the end of a second pressure relief pipe at which a second cut-off valve is provided is located above an end of a scavenging pipe.

A vehicle includes a fuel tank, a jet pump and a controller. The fuel tank has a passive side and an active side. Each of the sides includes a fuel level indicator.
