thanks again for the great Idea Rick, brilliant discovery owed to you, yes, the silver color you see is the copper coating just sanded off, I did use the brazing rod type silver solder, with the white flux, worked out great the only thing I did not do was to add a pressure fitting, not sure if I need to, but will try without it first, I did put one on my Corsair only because I have a 2 tank system and wanted to make sure the fuel would flow from one tank to the other, but on the Stearman I only have one tank, 32oz. only because I had it, my clamps are kind of crude but seem to tighten but not sure I can tighten any more with out making the slot wider, will see after the engine runs a time or two, thanks again...............Steve.

Genuine industrial grade silver solder has a gold appearance when brazed. And the white flux can only be removed with super hot water. Just want to make sure so your exhaust rings holds together. Super nice work!!
