[zubzub]

So if the 3/8" air line coming out of the top of my dry tank is not going to the gradustat any guesses as to wher eit is going.  I haven't fount it in my maintenance manual, and I have misplaced the parts manual.....

John,

I thought about using threaded rod but decided the threads might cut into the tank over time and probably cause the tank to rust. I'm pretty lazy anyway and the clamps were cheap.

I used laminated hardwood flooring for my cradle, like the original. I didn't want to put Al next to Al because of the high corrosion potential.

It sure would have been a lot easier to do it with the floor out!!

It has been a year or so since I traced out that air line but I'm certain it went to the gradustat. I was going to remove the line and plug the tank because it looked like a good place for leaks but decided it was a lot more work than it was worth. It makes no sense to run the line from the rear when the gradustat is only a couple of feet from the dry tank? There is nothing else in that part of the bus that uses air that I can think of.

I don't think the air tank or any air lines show up in the parts book. They are listed, but not shown, as I remember.
