Exactly where is that evaporator drain tube?

Under the accumulator on the passenger side firewall.

Exactly where is that evaporator drain tube?

Look for where your heater hoses go through the firewall, below the A/C accumulator mentioned. In the same oval hole punched in the firewall for the heater hoses, there will be a black plastic nipple poking out which may or may not still have a rubber 90 degree elbow attached. This is the A/C condensate drain.
