Interesting.
Have you previously removed the spider traps from the ends of the hoses?
If not, then the blockage you mentioned could be due to the awkward to get at spider trap on the drivers side (if yours is a diesel) still being there.
 
The video above would suggest that either there is a fracture in the plastic or that the channel supplying the drain outlet is filled with debris which is allowing the channel to flood and overflow.
Not an easy fix....
