I ordered a replacement freezer door expecting to get a complete door and only got a shell. When I attempted to install the ice and water dispencer I found that the supply hose to the water dispencer appears to be a one piece tube in the old door but the replacement door only has a plastic grommet co0mming out where the supply hose in the original door was all one piece running from the water dispencer to the coupling at the bottom of the door.

I was told that the water tube is molded into the door. My replacement door does not have this. Do I remove the water tube from my old door and try to snake into my new door? It looks like this might be hard to do.

Anyone that has replaced a freezer door please give me some help.
