As I continue to hunt for air leaks, I ran across this today. I have air leaking out the white, what appears to be an air hose fitting.
1. What is it
2. Is there supposed to be an air hose attached, and if so, where would it run to.
Any help, or suggestions would be appreciated.
Thanks
John

I think this is a ride height control valves? The white fitting possible had a rubber hose that was just a discharge line. Dose air come out all the time? Post a picture of the whole valve.
