The conduit includes a first section disposed proximate to the inlet opening and a second section disposed proximate to the outlet opening. The second section has an increasing diameter along its length. The conduit is formed by a first member and a second member both of which extend between the inlet opening and outlet opening to form a portion of the first section and the second section. The first member and the second member each include an engagement feature that extends between the inlet opening and outlet opening.
