Do you still need those plumbing diagrams? With some digging, I may have some that will help.

I have a similar problem on a 1993 center bath Excella. Have been thinking that it is a connection into or out of the tank. Appreciate your help very much!

frone,
Most likely the adapter that connects the dump valve
to the tank neck has cracked. Both of mine cracked at about the 20 year mark.

I can't answer the question of where the leak is originating, but here is the thread where I replaced the dump valves on my 1994 Excella. Should give you an idea of what is behind the belly pan.

Hi elkay, richard5933's link will probably more useful but here are some relevant pictures of our 29' "93" Excella that were taken during tear-down and including getting our tanks re-installed. It's still a work in progress so no pictures of finished plumbing, but it will look mostly the same as original. I'm providing links to three of our re-build albums on goggle Photos, so all of the pictures are relevant to the phase described by the title, but there will be a lot of not helpful pictures as well. Hopefully, something helps.

Good Luck.
