In known devices for pumping fuel, suction jet pumps are used which are driven by the fuel flowing back from the internal combustion engine and pump fuel from a supply tank into an impoundment container of a fuel pumping unit. In known suction jet pumps, the suction power is limited by the fact that the fuel stream applies itself to the housing wall, so that the entire area of the fuel stream is no longer available for entraining fuel. The device of the invention lessens this effect by providing at least one rib between the first partial section of the fuel line and the mixing conduit.

Suction jet pump with ribs for guiding the flow of fuel

A device for delivering fuel having a delivery unit, a main filter with a filter housing situated downstream of the delivery unit, and a drive line for driving a suction jet pump embodied in the filter housing of the main filter. As a result, the assembly and manufacture costs of the device are reduced.
