[hypoxia]

The existing valve was problematic in that all fittings needed replaced and it looked to me to be a continuous problem due to the bending of the air lines in a short distance between the two valves.  I spent less than an hour installing an air line that will never be a maintenance issue, I will never have to check it for leaks or even think about it.  It will only be charged when the brake pedal is depressed.  I also ran it by my Backyardigan who approved and explained how every part of the brake system works.  Unfortunately for me he is leaving for Prudhoe Bay, Alaska on Monday so I will lose a great asset.

I will be interested to see what you find with your tanks.
