any ideas as to where to find such a kit to convert now days? Sounds like
something that would work really well for me.

I'll get new empty tanks FYI if this is doable. I hear they're
supposed to hold up to 300 PSI test as part of requirement as propane
tanks?

The concensus of what I've heard is that while propane tanks will stand
the pressure, they are not as thick walled as tanks designed for air
service. Thus they will rust out much faster if the air in them isn't
thoroughly dry, something that's not to easy to achieve if you're planning
on using them for air compressor storage tanks.

Unless you stand them upside down it won't be easy to add a water drain
valve either.

I did use a 20 lb bottle for several years as an emergency "air pig" for
occassionally filling a flat tire. I installed a kit I purchased for about
$15 which replaced the propane tank valve with a new valve with a pressure
relief, a Schrader (tire valve) filler port, and a 2 foot hose with a tire
valve chuck on its end.

After reading comments to the contrary here and elsewhere I chucked it and
spent $29.95 on a genuine air pig.

HTH,

Jeff
