I did find something weird that maybe y'all can shed light on. This hose goes into the expansion tank. Pretty sure its not supposed to be split like that. What is it called and why would they do that?
This is a full explanation from the previous owner who worked on it.
The power steering reservoir hose leaking and the fluid dropped on the said hose connector which connected to the tank. The ATF caused the the said hose o-ring swelled and leaking. He tried to replace the hose but couldn’t remove it from the hard plastic pipe which connected to the water pump rear side, so he cut the bad end and spliced in half a new hose using a galvanized T he found in the toolbox .

He can see that power steering hose wetted with ATF. Keep the fluid off the coolant hose!!!

@Sapote
I'm thrown off with this last comment. Do you know the previous owner of my car?
Are you speaking in the third person?

I'm the previous owner of yours! Just pretend that it is the truth.
Ha!
Damn. I was hoping to get some service history and specs on what package I have.
This poor car needs so much love and work.

What do you mean when?... o_O
Well I got off topic. I am in need of what this hose is called so I can order. Mangos post called it:
"LONG HOSE - Runs from the heater core outlet to the connector on the rear of the expansion tank, about halfway up. This hose runs on the chassis rail, higher up than the return hose."
Is this my Heater Hose?
What's the best way to tackle getting the fitting off the heater core outlet? (Remove?)
I would prefer to replace this vicarious hose before it bursts. As the one placed on there feels like a reused water balloon. @Sapote does the ATF look bad? Or is it just build up? Would like to close this thread and chase my massive vacuum leak.

You're right, that said hose with the T added is the long hose from the tank rear to the cooled side of the heater core (red arrow in pic). I was wrong thinking the hose connected to the tank bottom bracket and to the back of the WP housing.

Best way to remove hose from heater core port: Unscrew the clam and slide it away. Use two large flat screwdrivers to wedge between the hose end and the firewall, and work it out. Be careful not to dent the soft heater port which can leak.

That power steering hose looks original old one connected to the bottle. If it feels hard like a rock then it is leaking and should be replaced to save the coolant heater hose from damaged.
To check for ATF leak: fold up some paper towel and wedge it between the hose and top of alternator -- tight so wind won't blow it off. Check paper for oil wet after 1 week. To remove ATF hose, you need to remove the left headlight for more space to pull it off with the Quick Connect, the white plastic release ring probably crumbled by now. Ask me if it is crumbled and how to work it out.
