    Thanks, I got it right and definitely kept the old one. Any small part like that gets stored for re-use, rebuild or emergency.

    The new leveling valve was identical to the old so I had it oriented right but it is super sensitive. I took me a few tries to get it calibrated right. All is well now.

    99% of the time no air to air bags, slider, ect is the regulator. No air to the tank is the emergency valve.

    I now know this and will not likely forget it. What blows my mind though is that after talking to 3 people at my local GD dealer, which is a big busy shop, not a one of them had any clue about this.

    Can't plug a computer into the airlines.

    Occam's razor. Eliminate what doesn't put air in it. Only one thing does.

    I really enjoy reading these type of threads. Learn a lot of trouble shooting information without having to go through it yourself.

    They want you to come for repair and gain some hourly rate money.
