I uploaded them to my site as I couldnt figure out how to load them on here.
I did not have a pic of the tube but pretty much you unscrew the top sanke part and the tube and spring comes out. The tube and spring are under pressure and getting them to thread and start takes a little pressure and luck. Its not so much that it will break your nose or fly around teribly but keep pressure on it until you unscrew it completely to avoid losing something.
The keg is a little smaller than a areg sanke keg. It might be 8 gallons in the tank, im not sure. It sure makes moving it easier than a carboy or a 5 gallon bucket.
