Air Pump on an 86 Dodge D100

No. all the plumbing is gone and I don't even see a bracket. The only reason I figured it was there was because of the diagram. The diagram doesn't really show it going anywhere but I believe it goes to the exhaust to burn excess gas. Not sure though. I need to get it smogged in order to register it where I live. I guess I'll hook up the cat and all the vacuum lines and try and smog it withou the air pump.
