I installed the rear air tank I bought last year today. I installed it behind the last differential and the tow bar I installed. It's a 12" diameter by 26" long stainless steel tank I got off eBay. I plan on running the trailer brakes and rear external air line from it. I already ordered the R-14 valve. This way if I loose all air pressure I still can stop the trailer I'm towing. That is as long as I still have over 4psi pressure left to apply the R-14 valve.
Getting the clamps close enough to bolt together was a pain. I did have my "expandable Vise-Grips" but it didn't work on the left side bracket for some reason. So I had to go "old school" by using some "tie" wire and a screwdriver. Now I just have to run the new hose and install the R-14 valve when it gets here.

In picture '1' you can see the fittings on the top of the tank. The closest one is the inlet with it's one-way check valve. The other one is the feed to the R-14 valve. Both lines are 1/2" .
