Abstract: An attachment arrangement has a fuel line formed as a plastic tube, and a connector for connecting the fuel line to a fuel supply system, the connector having a plurality of collars spaced from one another in a direction of a longitudinal axis of the connector and protruding from an outer circumference of the connector, an elastically widenable bush arranged on the plastic tube of the fuel line in a region which is slippable onto the connector, the connector and the bush being composed of a same plastic, and the plastic tube which forms the fuel line being formed as a rigid tube.

Abstract: A device for receiving a fuel delivery unit (12) inside a fuel tank, in particular of motor vehicles, is proposed. The fuel delivery device (12) is essentially completely surrounded by a damping element (14), wherein the damping element (14) is connected with a holding device (13) and essentially completely decouples the fuel delivery unit (12) from the holding device (13). The device (11) can be arranged via the holding device (13) in the fuel tank. (FIG. 1 in connection with this).

Abstract: Arranged in the fuel tank is a reservoir into which fuel is pumped by a jet pump connected to a return line from the internal combustion engine. The jet pump has a jet nozzle which is arranged in a holder formed on the reservoir. Between its inlet opening and the propulsion-nozzle opening, the jet nozzle has a bypass opening which is connected to a stub projecting into the reservoir. At its end, the stub is provided with a seat which can be closed by a closing element. Arranged in the reservoir is a leaf spring which is fixed at one end and which presses the closing element onto the seat. Together with the closing element, the bypass opening forms a bypass valve which allows fuel to flow out of the jet nozzle if a certain pressure is exceeded.
