Last week, I had the new air tank with lanyard valve installed. My bus was going in for state inspection anyway, and I decided it to have them do the air tank work.
Before dropped it off for the work, I disconnected the lanyard fro the valve, and installed the valve in the tank. I told the local garage that I would install the lanyard cable when I figured out where I wanted it. Right now, I just have a simple 1.25" circular ring (from a key chain) on it. It is easy enough to get to, I may just leave it that way.
Before I close, I have a big confession to make to the bus gods. When I first purchased my 4104 I was very much a novice and did not know there even was a wet tank in the rear. I drained the front tank regularly, but the one in the rear was never touched. When I did find out about the one in the rear, I tried to open the valve but part of the valve busted off in the process. It still held air fine, but there was no way to open it. I drove that way for another two years. In short, I drove for 9 years and close to 30K miles without EVER draining the rear tank. Okay, my confession has been registered, and my conscience is clear now. [It also feels better that I have a new tank and valve installed
