I believe the "to atmoshere" means the vacumn line just vents to open air.

That vacuum on mine is the one that connects to the vacuum reservoir. It doesn't go through the firewall.

"To Atmosphere" refers to the rollover valve on the tank. Fumes go from there to the EVAP cannister. Sitting without running, the fumes are stored, to be drawn through the lines after the engine is started.

Look under it for a smaller one that may be broken, or capped off. There should be more than one fitting there.

The only one that goes under it, is the line that comes from the engine/throttle body to the evap canister. It connects from the engine to throttle body, back down under the climate line and forks off to the evap canister and something else on the right of the engine.

Would it be easier if I snapped a few pics of my entire engine bay?

Okay. I have a question. Your '95 V8 is supposed to have the EGR system on the right rear of the intake & exhaust, with a solenoid that works off of vacuum lines. Is that still hooked up?

Yes, I believe so. It receives a vacuum line from the fork off the throttle bottle and another from the other side of the engine that its on.

I took a pic of it

Okay. I was thinking if it had been disconnected, they may have changed some other things too.

Okay, I found something else. This thread has a pic just like yours. Except on the T where yours is capped, he had a vacuum leak. That's for the line that goes through the firewall. Read this. In the pic of the rear of the ac control head, you can see where the missing line goes among the colored lines. He just needs a smaller line. http://www.jeepsunlimited.com/forums....php?p=4740095

Thanks for that Blue! Just gave it a read over.

Basically, I need to take the cap off the "T", add a new vacuum line that will feed through the firewall to the backside of the dash, correct?

Are there any real detailed write ups for the '95 ZJ dash removal that you know of? - To get to those colored lines. Most of the ones I've seen aren't '95 v8 specific and can throw you for a curve ball lol.

Got the dash taken off, wasn't too bad. Is this where the vacuum line from the "t" needs to plug in to?
Its directly underneath the big black air/heat box on the passenger side.
