An assembly for feeding fuel form a supply tank to an internal combustion engine, with a feed pump which is designed as a flow pump and the disk-shaped impeller of which rotates in rotation in a cylindrical pump chamber delimited by a suction cover and by an intermediate housing bearing on the latter and at the same time feeds fuel from a suction port in a suction cover to a delivery port in the intermediate housing to enlarge the production tolerances of a fit between the suction cover (7) on the intermediate housing, and in order to allow the two pump components to lift off from one another during the operation of the feed pump in order to flush out dirt particles from the pump chamber, the suction cover and the intermediate housing are braced relative to one another by means of a resilient connecting element and the suction cover and intermediate housing are permitted to move relative to each other in order to flush dirt from an area of the pump impeller.

An assembly for feeding fuel from a supply tank to an internal combustion engine, which comprises a feed pump (1) including a disk-shaped impeller (3) which rotates in a cylindrical pump chamber (5), said pump chamber is delimited by a stationary first housing part with a first pump chamber wall (13) forming a suction cover (7,207) and by a stationary second housing part bearing on the latter and forming an intermediate housing (9,209) with a second pump chamber wall (17), and at the same time feeds fuel from a suction port (23) in the suction cover (7,207) to a delivery port (25) in the intermediate housing (9,209), at least one resilient connecting element that connects said suction cover relative to said intermediate housing in such a way that a relative axial movement in relation to an axis of rotation of the impeller (3) is permitted between the suction cover (7,207) and the intermediate housing (9,209).
