No, as far as I know, all the different WUR's are the same. I ran a
used one from a ovloV in my 83 5kt for years. Vacuum ports pointed
differently, but other than that it was the same.

I suppose so, old fuel can get gummy, right?

nah, just remove it (don't let the torque of undoing the fuel lines be
taken by the mounting bolts, they are a bit small for that) and give it
a good going-over with some carb cleaner. Soak it well. The screens
are inside each fuel line connection, a small brush might help get to
them. Shooting carb cleaner or compressed air into one blasts the other
one clean, as I recall.
Do something like hang a rag over it to manage fuel spray when you crack
the fuel lines open, of course, and do all this work in a well
ventilated area, like outside.
