Melted power steering return hose

The power steering return was touching the engine and a hole melted in the side. I cant seem to get the right hose from the auto parts stores around me, they keep ordering them for me and when I get there it is the pressure line. My question is can I just use 3/8 id hose or does it need to have the reducer in it that the old one had. The old one had a metal clamp on the hose with what looks like a reducer in the middle.
