Yes, and its not even April 1st...there is no way a sensor can get any
negligible air through multiple feet of stranded wire unless its specially
designed somehow to have a void in it, or something specific.  If I'm totally
mistaken and this is in fact truthful, is there a technical document anyone
can reference?
