I just spoke to a mechanic that does certification for tanks used to
store gas for propulsion, not fridge/stove. He said the inspection
was pretty well just visual for those tanks, and that there had to be
some sort of ID tag on tank.

The point is that up here in BC I find more often that the filling
stations want to see a cert. sticker. It used to be no problem, never
got asked, but its changing now.

NOTHING certain about that at all. I know 2 volks who referbed their own
tanks,
tag-not-included on the tank, and apparently, because the tanks
appeared in
such fine, repainted, spanking-clean shape, they've never had any
trouble
getting them filled. These people are in 2 different states (U.S.).
