Isn't there a danger of sucking vapors into a vacume cleaner with an
electric motor?  Doesn't feel to safe in my judgement.   Who am I to know
since I have not tried it but then I am still around to write this note.

If however, you are blowing air into the tank than that is a different
matter.  PLEASE CLARIFY AND ASSAUGE MY FEARS.
