Closer view



Hose looks ripped from the end. It's near the O2 sensor.

 

From picture it looks like AC drain tube

 

Well damn. I'm still new to these engines but I was hoping it was linked to my heater blowing cold air which I might think is the heater control valve.

 

make sure the heater control valve is hooked up to vacuum correctly. its on the firewall passenger side near the big black canister thing

 

I can confirm it is your AC drainage tube.

 

I am literally too lazy to walk out and look at either of my SC's, but isn't this the hose under the vapor recovery tank? I removed all of that system on my race car, so it should be really easy to see, but that involves unlocking the trailer, tripping over all of the stuff in the trailer to open the hood, etc. Much easier to sit here and type and create controversy.

 

I haven't been behind the dash to check but it makes sense that it is connected to the AC. That line passes through the firewall on the passenger side where the fans/air control box are. The Toyota Celica had a AC drain there too.

 

Can confirm it is the AC drain. If you turn the car off after using the AC you can see some water dripping from it. Could have been placed better but whatever it doesn't hurt anything.
