i am not sure if it leaks. i'll have to put some water in there and see.
probably does. sink and shower grey water just goes straight out i guess...
i do have an original cast aluminum 90 degree elbow connector for this.
That valve was obsolete over 40 years ago.
The fix is easy.
Remove the vale and all of it's associated parts.
Fiberglass a new Thetford outlet flange to the fiberglass tank.
From there, you can configure the drain system most any way you want to.
