Well now ya got my curiosity up I always figured I'd need a
pretty BIG tank to hold the vacuum up for any measurable
amount of time.
I've got an empty 50 lb. Freon tank that I cam easily plum in
series with the wiper motor. Think I'll do an experiment and
see it that would indeed work. Gotta say, I don't think even
that 50 lb. tank would be a large enough volume to make much
of a difference.
