I tried with the fish tape again last night with no luck. I crawled back into the engine compartment and finagled my arm around to reach up into the "drain" that drains into the bilge. I couldn't reach very far into it and couldn't feel and type of a pipe or anything. It feels like more of a flat, wide area where maybe multiple things drain. I'll keep trying with the fish tape. Maybe there is some type of pipe that is clogged and I'm just not getting the fish tape into it. It is very, very difficult though with the engine in the way.
Any ideas are appreciated. Thanks again, Greg
