A motor vehicle pump arrangement includes a pumping unit having engagement steps, and a mounting arrangement which mounts the pumping unit to a motor vehicle mounting structure which corresponds to the pumping unit. The mounting arrangement includes a vibration-decoupling body having a ring shape, and a clip retainer which is attached to the vibration-decoupling body. The vibration-decoupling body radially surrounds the pumping unit, supports the pumping unit, and is attachable to the motor vehicle mounting structure. The clip retainer axially retains the pumping unit. The clip retainer includes a retainer frame which extends in a transversal pumping unit plane and which is axially supported by the vibration-decoupling body, and retainer arms which axially project from the retainer frame. Each of the retainer arms engages a respective one of the corresponding engagement steps of the pumping unit so as to axially retain the pumping unit.
