An aggregate for feeding of fuel from a supply container to an internal combustion engine, particularly of a power vehicle, comprises means forming a feeding chamber, a feeding pump having a feeding member rotatable in the feeding chamber, an electric drive motor for the feeding pump and having a motor armature connected with the feeding member of the feeding pump, means forming a space which surrounds the motor armature and through which a fuel flows, a weak magnetic tubular part surrounding the motor armature and having an inner wall, at least one permanent magnet having a substantially ring-segment shaped cross-section and arranged on the inner wall of the part, and an intermediate wall separating the feeding chamber from the space, the intermediate wall having a tubular projection which surrounds the part and a pocket provided on the intermediate wall inside the tubular projection for receiving a portion of the permanent magnet.
