WHAT IS THIS???
When changing my valve cover gasket I was removing the valve cover and noticed that the hose going to this fitting was rotten and basically falling apart I want to know if this is part of the a\c to know if i should replace this as soon as possible or if it can wait. Also where can i get a haynes manual cheap??

Why leave a problem broken? Im sure its easy to just buy some vac line and fix it up so its correct. Even if your are running fine. If its wrong its wrong.

pepboys has them for 19 bucks and those hoses are pretty cheap also. If you have 25 bucks you can probably replace the hose and get a manual.

Haynes manual should be had at any local auto parts store, and worth every penny! If not, Rockauto.com should be am alternative or Amazon.com

no matter what it is, it looks like it has a nice little wet spot right under it. So even if something is coming out or going in it has some importance to the engine. Replace it soon. Not replacing hoses may not show any issue right away even if its an emissions part, but will cause you problems. I wouldnt jump to changing all the hoses just yet either. Just inspect what you can and change what does not feel solid.

Evaporative (EVAP) Emission Control Systems
Since gasoline vapors contain HC, these vapors must not be allowed to escape from the fuel tank to the atmosphere. In the EVAP system, a hose is connected from the top of the fuel tank to a charcoal canister. Gasoline vapors from the fuel tank are stored in the charcoal canister and then purged into the intake manifold when the engine is running under certain conditions.

Never seen a vacuum line hooked to a dryer before. A/c system has massive amount of pressure dont know how a vacuum line would stay on it. Not saying thats not what it is. What other kind of lines are hooked to that can?

Bingo...
Golden.. just last week i found my line was split and off the same spot. That vac line runs just behind the valve cover and has a clip to firewall. I was able to cut an inch or two off and reattch it.
