Off hand I think there is 4 vaccum lines that come off the pass. side vaccum junction. 2 of them are connected 1. to the egr 2. to the gt-40 upper intake. Now there are 2 others 1 long, 1 short. I have no idea where they go, and I don't know if they even go anywhere, and no I don't know if I am losing vaccum my motor is all apart this is just a question I would like a little help on.
Maybe people have there's connected?
Thanks
Mark
Pics might help, if possible. But it is safe to say that a vacuum line must be hooked to something, or you WILL lose vacuum.

no I baught the car. It has no smog pump but I didn't know 2 lines went to pollution. If I could find a pic that would be great. And yes I know they should be plugged off but there not.

There is a tube that hooks up to your crossover pipe(behind the heads) and then connects to the back of the smog pump. If you have eliminated the smog pump, there is no need to worry about it. Just cap them off.

I can take a pic of the connector hose if you need it.
