Paul,
The best thing to do is cut a small access in that large panel in the right rear compartment. Measure down approx. 3" from the top of the compartment, and drill a hole large enough so you can see the black water tank. On the top of the tank where you are working you should be able to locate the flush nozzle. Now you can cut an access hole large enough to work on that nozzle without removing the whole panel.
It is suggested that you remove the nozzle and drill out the holes one drill index size larger. When you are done you can use stainless steel or aluminum to cover that access. The newer CCs have that access panel, and I have seen older CCs that have a rectangular score mark where the panel should be. To stay out of trouble, I would use a block of wood, or some type of spacer so you are not drilling much deeper than the thickness of this panel until you know how close the panel is to the tank.
