Conan the Compressor - Vacuum Pump Possible?

I used my Harbor Freight vacumn pump (eductor) to outgas the MT propane tank I use for a portable air tank. The tank held about 26"hg w/o any signs of deformation. Maybe you should add a filter to your tank, that way you will have a vacumn cleaner, (sorry, could not resist!!!) Even after multiple flushings with air, there is still a smell of the odorant.

To get rid of the smell (reprint of earlier post): I have tried various things to get rid of the odor from propane tanks that I've reused. I have just tried the only one that really worked: chlorine bleach (e.g., Clorox).

I have a 10 gal tank that I wanted to use as a portable air supply. I poured in about a cup of bleach, sloshed it around, let it sit, sloshed a few more times. After about 24 hr., I drained the bleach, rinsed with a little water and filled with air. The air was totally odor free. Well, it smelled a little, more like paint thinner than anything.

Note - I did this with the valve on, it would be easier with it off, but probably not worth the effort.
