possible fix for a/c

[E150GT]

hey everybody,
i have had this a/c leak in my 86 420sel since i bought it last year. i had it filled with dye and bought a uv light but could not find any leaks. well now its been humid here in texas and my ac has been leaking water on the drivers floor for some time now and i havent looked under there until today. i was expecting to maybe replace a hose that was dripping on the floor but as soon as i put my hand on the carpet it felt oily and wet up by the top of the gas pedal and i instantly saw lots of dye. when i pulled back the carpet i couldnt find the drain hose but i saw two hoses, one was blu and one was covered in what looked like rubber going into a little aluminum looking block of metal. there was clearly dye all over the blue lines fitting and all aroud the immediate area. other than below that fitting i didnt see any other dye anywhere else so i tried to tighten that fitting as best as i could (which wasnt very good because i have no room and probably could have used better tools). anyway we will see if the leak stops later but another thing is condensate was forming all over the place down there and it doesent seem to drain off any where except to drip on my carpet. should there be some way to keep the condensate from destroying everything down on the floorboard? i had planned on this as a long term toy but i cant justify 1800 dollars on the a/c plus a rotted out interior from moisture.
