That's not quite what I understand it to be after what the pilot told me.  He said the tube DELAMINATED
internally, not quite the same, although the end result is.
Unless there was a stoppage in the tube, there would be almost no vacuum in the tube.

Thanks for the recent information assistance regarding the Seawind accident.
The owner is planning to rebuild.  A flex tube purchased through
McMaster-Carr was attributed to the engine-out.  Used for the induction
system, the inner wall collapsed under manifold pressure, although,
reportedly, it was rated for the vacuum.

I would think it was a turbo so down stream of the turbo there would
be pressure of course. If upstream and there was a filter there could
be a slight vacume.

Never the less what ever it was it is always a good idea to think about
what would happen if a hose collapsed,
Perhaps we need  a check list of do's and don'ts.
