Buy Gas Hose - 1997 Atwood 3 burner stove

Hi...

I brought an Atwood 1997 3 burner stove. I want to attach a propane tank to the stove but i'm unable to find a gas hose for the stove. Is the stove obsolete and should I move on?????

I can provide a photo of the connection but don't know how to upload photo.

Thanks
