Thanks for all your responses. It looks like we can conclude that the TF 3200 used 1/4" lines all the way back to the rear hose and 3/16 on the rear axle. The 3100 uses 3/16 throughout. I called inlinetube today and told them that the members at Stovebolt.com determined this to be the case. They were very accomodating and are going to make up the correct lines for me and send them to me at no charge. They even told me I could keep the lines they sent me originally (all 3/16"). I can live with that! Inlinetube even learned something thanks to Stovebolt members. Thanks again for all you help guys. Things would sure be a lot more difficult without this great resource.
