Propane Tank to Vacuum Tank conversion

Has anyone ever attempted to use an old propane tank as a vacuum tank(opposite of a portable air tank). I was wondering if the new-styleover pressure release valve has any limitations on allowing a vacuumto be made in the tank. I would think that for propane usage, theremay be measures to avoid flash-back. If so, I may need to remove thevalve and replace it with a 1" NPT fitting and some reducers. Anythoughts?Thanks,Mike
