Had the same issue with mine. The Valterra adapter was the only one I could find that worked with the new hoses and the old connection. With my set up I have to remove the adapter when when I'm done emptying the tank because the cap doesn't fit in the adapter. Not a bid deal but.... make sure you keep track of the adapter o-ring as it fits kind of loose. I ordered a couple extra after I lost the first one. The adapter doesn't seal very well without the o-ring and it was an unpleasant lesson.
