Hey Tuts 59, we're HVAC pipefitting brothers. I'm retired Refrigeration Pipefitter Journeyman. If you have to fabricate a new pick-up tube, I think the silver solder and corresponding flux for steel pipe would be a good choice. Or, as HRL noted, just flux coated brazing rod, Sil-Fos seems to be a little finnicky on steel.
