I'm pretty certain all those ZF pumps are the same, David, as long as
you're talking about cars from 1987 on.  The same kit should serve any of
them.  The main differences I've found ('87 5ktq, '91 200q20v and '90 V8)
is the bracket system specific to each model.  The brackets all vary, but
the pumps fit into them the same.

There's a good write-up on pump resealing in the Bentley for the '91 200q20v.
