Abstract
The invention concerns a motor vehicle fuel drawing assembly comprising a housing ( ) having a ring-shaped chamber ( ) and a filter ( ) arranged in said ring-shaped chamber. The invention is characterised in that it comprises at least a plastic annular lip ( ), cast in one single piece linked to the housing ( ) or to the filter ( ), made of a material capable of being elastically deformed, and shaped along an oblique direction relatively to the axis O-O of the filter ( ) and the housing chamber ( ), such that said lip ( ) is urged to rest, with elastic deformation, and along a direction with tangential components by its free end ( ), against the surface opposite ( ), the other surface of the filter ( ) or of the housing ( ) arranged substantially transversely to the axis (O-O) of the filter ( ) of the housing ( ) chamber ( ) to ensure tightness at that level between the filter ( ) and the housing ( ).
