Take a look at
these two photos. In the first photo, item #1 is the remains of a broken vacuum hose. I don't know what it did, or why it broke, but it went to a valve that I was unable to get a picture of. The clamp holding this valve on can be seen as item #3, in photo 2.
Secondly, item #2 in both photos appears to be another valve of some sort, but I have no idea what it is or what it does. It isn't obvious in the picture, but where the rounded part of the valve thing meets that big nut, has completely detatched. Was it ever connected in the first place? I have no idea. The point is, there's no connection between the two. However, the tube/valve combo on the bottom appears to be intact. So my question to you, the MustangWorks community, is...
what the hell is this crap?
I assume all three valves there are related to the AIR pump, but my service manual is incredibly vague (yes, I want to see pictures of the 2.3L Turbo as I try to disassemble part of the 5.0. That's incredibly helpful.

). The car runs fine now -- great, in fact -- but I'm trying to track down an annoying check engine light that seems to be related to my EGR system. Any help or information I can get would be great, but I have a feeling most of this stuff is beyond my ability to repair.
