I have posted on my thread about our restoration of the 1976 31' Sovereign
with our frustrations with the black tank. No one has responded yet and we need help.
We bought what was called the "correct replica tank" for it and the threads on the tank do not match the original metal flange that screws into the tank. We tried another one after buying it from the local RV dealer. That doesn't work either. DH says he is totally frustrated trying to get something to work on that tank. Does anyone know what else we can do? A source for other flanges? Retrofits? Hints, suggestions, ideas, thoughts, and guessed appreciated.
