John,

I can't verify this, but it wouldn't surprise me at all. Tube frame members can make great reservoirs/accumulators/pathways for air, hydraulic oil, freon (generic sense) and other non-corrosive gasses and fluids.

Indeed, it just made me think about the fact that I am having fits with where to place my accusump. One or both legs of the roll hoop could have made an excellent accusump if the tube had been machined out and a piston & plugs made for it (both of which would be easy to do for most any descent machine shop.) A couple of bungs, one high for the schrader valve and one low for the on/off valve, and Bob's your uncle.
