AFAIK all B's, and many BL models before and after that, came with a
double-sealing radiator cap that has a spring-steel disc that seals the top
of the radiator filler *above* the overflow port as well as the rubber disc
that seals below the overflow port. If you have one of these the system
will suck back any coolant from a catch tank ... as long as the overflow
tube reaches the bottom of the container, of course!
