I have my vacuum hooked up with 1" flexible plastic tubing (Tygon) and it is
not grounded. I don't see any need--there is not enough air flow in a
vacuum line, even with minor leaks, to generate much static electricity.
You really have to have dry air, vigorous motion and very good insulation to
generate sparks.
