My first thought was JB Weld, but the tube that is leaking is in the second row of a five row core, and JB Weld is thick enough I don't think I can "flood" the area well enough, thus my look at the Devcon plastic steele. Going to have one more shop look at it. Will post results if I try to epoxy it. Thanks everyone.

I use a pencil flame propane torch to loosen the solder at the tube. Like I said, low flame and be quick. have done it numerous times.

The trick is to do it once!

when removing remains of the tube ,I heat the solder just enogh to pull the tube out. I don't let the solder completely melt.
