Step one of disassembly will be the removal of the air hose from the tank valve. This we will not use in our build and it can be trashed.
With the hose removed we can see that we can now get a wrench or a socket securely over the fitting still attached to the tank.
Using your socket set or a hand wrench very carefully remove the fitting from the tank. Take special attention to the hole where the hose was set if you use a hand wrench so you don’t mess up the threads.
Here we can see the fitting removed from the tank. At this point inspect and clean the threads of the glue they used with a wire brush.
