I got out the old parts, got the new parts and the underside looked pretty empty. However when I go the new Thetford flange for the tank, it was a female connector, just like the TANK! I find out later that I didn't need the thread-on or bond-on connector but the glass-on.

What to do? I didn't want to glue anything to the tank for future repairs. I made a male-male connector to get the females together. This worked well but the bend of the 90 then did not match the output pipe. I found a vent 90 angle pipe that was a shorter and sharper piece. It fit well. I may have a problem with a tighter angle out of the black tank but we will see.

Here are some more photos.
