Beschreibung
Zusammenfassung:	The device for conveying fuel from a fuel tank (10) to an engine (18) of a motor vehicle has a conveying unit (14), communicating on the intake side with the fuel tank (10) and, on the pressurized side, with the engine (18), and a return line (22), which leads to a jet pump (24), located near a tank bottom (11), that pumps excess fuel via a mixing region into a reserve pot (12), from which the conveying unit (14) draws fuel. According to the invention a siphon-like mixing region (29) is provided between the reserve pot (12) and the tank bottom (11). An opening (32) or a filter element (48) is provided in a transitional region (31) of the mixing region (29) to the reserve pot (12). The opening (32) or filter element (48) which extends parallel to the tank bottom is closable by an axially movable closing element (44,51) so that a fuel flow can occur into the reserve pot (12) but not back from the reserve pot (12) into the mixing region (29).
