I too have used this tool for many years on my MGBs and VWs, and it
works great!  It is made in England, hence the discovery first the
British car enthusiasts.  I use it either with an extra boat trailer
tire or spare, or more recently with a portable compressed air tank.  I
find it works best at about 15 psi, it is hard to seal over that.  It
will overfill the reservoir, so you need a "shop turkey baster" to
remove the excess.  You should also use this sophisticated tool to
remove as much of the old fluid in the reservoir before starting.

Makes flushing and bleeding a 15 minute one person job!
