Think I found my air leak

[j_boucher]

Since I got the truck been trying to find where I have a small air leak , I believe I found it today , the cab level adjustment (don't know the real name) small square looking box , well under it I hear pretty good air source from those little air lines . The adjustment box works fine though

I have that same leak. It's the cab leveling air valve. There's a rebuild kit or you can just buy a replacement. Mine leaks profusely
