Re: egr valve vacuum line
Wish I could help ya more, as I have little knowledge of carbs, only FI . For your o2 sensor, it will be a purple wire, and should go from sensor into ecm.

The purple O2 sensor wire goes into the ECM harness just to the driver's side, rear of the engine. Do a search for vacuum diagrams.
