sbrem Posted April 28, 2008 Share Posted April 28, 2008 Can anyone tell me exactly what this is and what it does?Its got 2 air lines going to it. One Tees off the line going to the right rear brake chamber right after the quick release valve and the other line goes to the air tank. The part number on it is Wagner AE-21882. This is on my '65 B-61. My B-70 does not have one. Thanks. Quote Link to comment Share on other sites More sharing options...
