Valid air ride system tag axel pressure regulator plumbing

Hope someone can help. We have a new to us 2013 American eagle with tandem axel.

Someone hacked up the airlines for the leveling system. I have everything connected back up but have a question about the regulated air for the tag axel.
For the supply line to the regulator would you connect directly to the air tank? If so would you need a ppv screwed into the tank then the line connects to the ppv and then to the pressure regulator and from there to the actuator block for the tag?

Right now someone did some crazy stuff and pulled the supply line from one air bag to the regulator.

Any help is appreciated
  • I dont know anything about your coach. You should have a supply tank, that is separate from the primary and secondary brake tanks. If you pull from the supply side, you already have the benefit of the existing PPV

    You should be able to use the same air feed that is used for the rest of the leveling system
  • When I was adding a tag to truck I would tee off a line from tank, to open/close valve, with quick release, to adjustable regulator then to bags. Most of mine where air lift. I used a separate system, nearly same, except the regulator was mounted on frame.
    On trailer, I would tee in past leveling valve, then valve with quick release

    I was hoping someone would’ve been able to respond as well but thank you for looking.
