Aux Air Reg

The hose diagram I have doesn't show the aux air regulator on it, or at least I cannot find it. I beleive its DD diagram. Can anyone tell me where to connect the hoses for it. Its a '73 2.0L D-Jet. Thanks

On the page: http://www.pelicanparts.com/914/technical_specs/914_20FI_diag.htm,
it shows the valve right in the middle of the drawing. Ours is connected to a boss on the air cleaner and a boss on the intake plenum.

I have that drawing. I named the wrong part, actually I have no idea what part it is. It is mounted on the fan shroud. I think it is for the air supply, but I could be wrong. Sorry about the part name thing.

What does it connect to? What does it look like? How many connections? Where on the fan shroud?

If it has two hoses coming from the heads and not much else, then it is the "flashback valve" (just a flame arrestor and two-to-one converter).

If it has a whole bunch of stuff on it including a drive pulley, it's a smog pump or maybe an A/C compressor. Check the 75 1.8 diagram for some idea of what connections the pump has.

If it ain't those, please tell us more so we can help figure out what it is.

Okay, here we go. Looking down on the installed engine from the back of the car, the part is mounted on the left side of the fan shroud. It looks like a sideways frisby with a pole through the center of it. There are two spots to connect hoses to, and an electrical connector for 2 wires. Um, its gray in color on my car. Other than that I dont know. It is not an A/C condensor, or a smog thing. Thanks for any help.

Oh, Dave you also asked what it is connected to. As of right now there are no hoses comming off of it. It just has 2 outlets for hoses.

Sounds like a 1.8 (also used on other cars) aux air regulator. Verify this by blowing into one of the two hose connections. Air should come out of the other. Then hook up the wires to +12V and ground for ~5-8 minutes. Then try blowing again. If no air comes out, then you have a properly-functioning auxiliary air regulator from a different car.

That sounds strange to me. I do have the aux air regulator that is on Daves drawings. Thats hooked up and running. Is there any reason that they would have this thing on the 2.0L engine? I swear, PO are strange... Thanks for all the help. Im just confused as all now
