I found some glass tubing the other day and my next order from McMaster-Carr will include a piece of Borosilicate Glass for the MAP tank. It's $8.99 per foot, and I'll post the results if it fits and if it works out ok.
Unfortunantly, I have already checked there and theirs is 7/8OD x 5/8ID 1/8" walls. Needs to be 7/8OD x 3/4ID. Or 22mm x 1.6mm walls.
