Well, this is a sign that you might want to visit the professionals and have them leak check and evacuate the system prior to attempting a repair. Trying to pinpoint a leak by listening is not at all a properly way to do it, plus there is likely still some R-134a refrigerant (technically it's not R-12 Freon) in the system which should be professionally evacuated.

Also, there will be no physical connection between the heater core and the evaporator core, and the condensor is a long ways away from the heater core.

I'm all for folks DIY'ing as much as they safely can, but I am coming to the conclusion that it would be in your best interest to visit the pros or find a friend/co-worker with the knowledge and tools to perform this work properly. You are aware that if you replace a line/hose you won't be able to just buy a few cans of R-134a and get the system cooling effectively, correct?

Per the factory service manual, "An A/C evaporator core orifice is installed in the condenser to evaporator tube (19835) to meter the liquid refrigerant into the A/C evaporator core."

If it's truly the line with the orifice that you need, it's called the "Condenser to Evaporator Tube" per the factory service manual, and the manual lists the part number as 19835 although this is obviously not a Ford part number format. I'm not sure how to translate "Service manual part number" to "Ford orderable part number."
