I have a vacuum line on the left side of the intake manifold that I cannot figure out where it needs to go. The vacuum elbow coming of the rear left of the manifold it a 2 connection elbow. One of the vacuum lines routes to the EGR solenoid with another line from the solenoid to the EGR valve. I cannot figure out where the 2nd vacuum line from the elbow routes to. Shoebox, in his picture of this area, shows a single connection elbow coming of the manifold, but mine is definitely a 2 connection elbow with both vacuum connections pointing to the back of the engine. I do have a vacuum line from the right rear of the manifold that routes up to the fuel pressure regulator, so I know it doesn't go to that. Anyone that can look and/or tell me where the vacuum line attachs to?

 

The 97 had a recall on the AIR pump, and they added a vacuum connection on a "tee". I think they were supposed to use the nipple in front of the one for the EGR, that also connects the Opti vacuum hose. Is it possible they connected the AIR recall vacuum hose to the wrong place?

This was exactly what I needed. Thank you very much.
