I just went out to my '86 5ktq parts source (that has no evap box in place) 
and discovered that tube the small hose from the evap box connects to is a 
plastic elbow.  So I pulled the larger drain's rubber tube and felt with a 
finger while turning the elbow around, and there's another rubber hose 
going downward from the elbow.  Too many spiderwebs to deal with beneath 
the car in that area, so I didn't try to see where the hose leads, but I 
suspect it's just down to drip below the level of the footwell pan.  Maybe 
that's the source of the puddle that drips when running the A/C and sitting 
in one spot.
