I did a very stupid thing in not labeling the hoses when I removed them from my 3" heat Exchanger. I removed it to clean it out and get better access to the Hurth Transmission for servicing. I cleaned it up, painted and brought all new hoses. Now it is time to re-install and I can's recall where the hoses get connected. It is an 89 cat 30, with Universal 25XP Engine. Standard Hot Water Heater next to the Fuel Tank Does anybody have a good diagram or even better picture they could share. Everything is ready to go back. If you want to send it directly, my e mail is wjaffe@optonline.net
