The hose to the right, which from what Im guessing is supply line to the heater core????

Anyway it turns into a geyser this morning right as Im hooking up the trailer to head for Texas Heatwave. Said screw it jumped in the wife's car and just went to spectate.

Got home thinking all I needed to do was replace the hose, well guess what the hose is fine, its the neck that hose slides over that sheared off, glad they made it out of plastic

anyway how much of a PITA is this gonna be to replace? I tried spinning the plastic piece off and I could spin it til my face is blue and its not going anywhere. PLEASE tell me this is like one of the old ford lines that you can stick a tool inside to release some fingers holding in on and I dont have to pull the whole dash out just to fix this crap line.
