Got a 20+ yrs old Devilbiss compressor that has has relatively few hours on it, but I never drained the tank regularly and has doubts to its integrity. (Don’t want to find out like a friend of a friend who ended up getting his head crushed when his tank exploded while he was next to it) The other reason is its only a 12 gallon tank and would like to up the size to at least 25 gallons.
So far, I have not found many sources for replacement tanks, and it appears the cost of a replacement tank would be very close to buying another new compressor.
Looks like new is the only (or best ) option. Any comments?

I'll bet you could get your tank inspected, but that might be really expensive too.
I thought of that, but came to the conclusion .
when i was in service, part of my MOS was testing/ checking comp. tanks. let all pressure out. tap w/ peen of ball peen hammer, if soft...let it go.
As for replacement....the comp. you have might make a good spare for new tank??
Current thoughts are to get a compressor whose motor/cylinder mounting plate can also accomidate the old stuff and keep the old to serve as a spare. But you know that the old stuff will never be used and the day AFTER I get rid of it, the compressor will experience a failure! <G>
easiest replacement : go to a propane supplier and ask for an outdated tank in your size : they have to revalve or get rid of them after 10 years and it usually is cost prohibitive : hence they have many from 5 gal to 50 and usually dirt cheap. I have a friend with a fabricating shop who uses a 50 tank as a resevoir : works great.
I would definitely replace it. But, not necessarily with a new one. Depending on your local supplier, you may be able to find a decent used/rebuilt compressor at a good price. Then again, if the tank is the only thing that is bad, you might want to hold out and try harder to find a replacement tank. Check with the manufacturer, a compatible tank might be available. I have several "older" tools that I have been able to keep running with current replacement parts.
Good luck.
Anyone know of any sources for replacement tanks??
I wonder if you could buy a portable air tank, and somehow mount the compressor to it? Or maybe keep them separate, but hook up to the portable tank with a hose.........
Q: How many men does it take to change a roll of toilet paper?
A: We don't know; it has never happened.
Replacenment tanks, both ASME rated and unrated are available from SpeedAire and are sold through Grainger, and I think Harbor Freight, Northern Tool and probably a few others. A 30 gallon ASME tank costs about $250. An 11 gallon ASME tank costs about $100. They are available in all shapes, sizes, with and without mounting plates, etc.
My recommendation would be to look at the tank you have first You can rent a mechanics boroscope for about $20 for a half day and take a look inside the existing tank. If the bottom surface is free from any significant pitting, it should be safe to use. If you are not going to use it for painting, spay some WD-40 in it after you look (and see no pitting) If There is noticable pitting, rust or thelike, find a proper replacment tank for your application. The tank will not cost more than a new tank/compressor combo.
Get an ASME certified tank that is rated at a minimum of 125% of the maximum operating (working) pressure of the compressor. While you're at it, get a new pressure relief valve. Get a good, easy to use drain valve, too, and use it frequently.
