Rick I'll be glad to help you out with your tubing system. I may be able to help you with an evaporator upgrade as well. I'm about to outgrow my 18x72 rig. She's not perfect, bu I've made about 80 gallons of syrup on her the last three years combined. 18x42 drop flue behind an 18x30 syrup pan. The syrup pan is for a 30" wide rig, I turned it 90 Deg and put a bulk head fitting in to connect it to the flue pan. I'l be cooking tonight, you should run over after you get off work. Or come over this weekend and walk through the woods and see my rig. I was planning on boiling another 2 years on this set up before expanding again, but I keep finding ways to move sap from all these tappable trees. I'm thinking of selling my boat to upgrade to a 2x8 lol Lord help me. I've got the bug so bad!
