tank problem fixed..put barbs on tubes and put a du-bro 8oz. in ...i ordered the the dubro barbs,and by surprise there are four in a pack for 1.58 or so..i thought it would be two from the picture..oh well i have extra..try some old solder my dad had at his house from 25 yrs ago for copper pipe..it had got old..so i just pull the electrical solder out..seems like it will be fine..easier too..hard to beat du-bro tanks,sullivin tank going in the trash,it was to flimsy..
