The original wet air tank in my 1962 4106 is pitted fairly deep where the wood blocks hold it to the bulkhead.
Options that I have come up with
1) sand blast tank, J B Weld the pitted areas, powder coat. and hope for the best
2) buy a new tank, first problem the only tank I have found that will fit the area is a 3 gallon. That is 2.3 gallons less then stock.
That could mean something if the compressor fails on a hill and I need a lot of brakes. Second issue is it is really a horizontal tank, big time air line moving.
Any and all thoughts.
I had a coolant tank do the same thing. I ended up taking it to a fabrication shop and they built me a brand new tank out of stainless steel so I will never have to worry about it again. I forgot what it costs but it was exactly the same size and had the same exact fittings as my old tank so it fit perfectly without having to build new brackets etc. which can be time consuming.

LOL. Oh to be so old and rich that such trivial things like a custom built tank, are so cheap, they are but a drop in the bucket ;D :D ;D
You handed that one out, Gary ;D
Check with Luke, Sam Kaylor, and truck/bus wrecking yards I'm sure you can find a suitable replacement tank.
FWIW moving fittings is not that hard with DOT approved plastic line.
;D BK ;D
It depends on how much peace of mind you want and how much money you want to spend. I had a rusted horizontal tank on my first Eagle that actually blew a hole out about the size of a dime. I wire brushed it, put a big wad of JB Weld in the hole and smeared it out on the outside, then painted it after it cured. It still holds 120 psi twenty years later, although it could probably (or should) blow at any time.
Sandblast the tank, if the sandblasting does not carve out holes, treat it with rust converter acid, fill depressions with epoxy, and paint it. It might be prudent to tap the tank all around with a hammer first to see if the metal seems to be the same thickness all around. It could also be rusted on the inside. Otherwise, it's time to hunt salvage yards for someone else's rusty tank, or buy new.
Down load the Velvac tank catalogue they should have the tank,school buses have large tanks check with Chalks in Houston.You can always double the tanks and use connections from 1 tank or in connection on 1 and out connection on the other,there are always connection ports to tie the tanks together

Well John, I figured a couple hundred dollars or whatever it cost me would be much cheaper than a repair while in the middle of Nevada on a hot summer day if my tank sprung a leak and my engine burned up. I have a Series 60 and I thought a new tank seemed like pretty cheap insurance. :D
FWIW the tank is probably rusted from the inside out. This presents the solution of coating the entire air tank with a good 1/4" layer of JB?
If no OEM fit tank is available (no you should NOT go down in tank capacity) you could, provided room exists, use twin tanks and daisy chain them together.
checked with Velvac, no luck. already called Luke & Ted Campbell nope, I did a search for tank fabrication and will be calling a few tomorrow. The way I look at it if we brake down in timbucktoo a $300 cost (if that is the cost) for a new tank would be cheap & save a whole lot of time.
An example: just do an online search for compressed air tanks.

I hear you Gary. And the reality is, I would have done the same thing without thinking twice.
Keep looking, there's infinite tanks and variations out there.
Don't limit yourself to bus related, or model specific.
There's tanks out there with numerous universal type bungs located all over it, most will stay plugged, attach to the ones convenient to your needs.
happy coaching!

The problem hear is I want a tank that is certified for air brake.
All air tanks are ASME certified there is nothing special about a air brake tank,the DOT standard is not much all I can find in the DOT manual they rated at 150 PSI if leaking replace or repair
