NOS Type 3 tandem MCs used to run about $125; now they seem to have 
doubled. I get quite a few NOS MCs sent to me to inspect, before the buyer 
goes to all the trouble to install them. So far, they've all been fine.

It will, but it's slow. I prefer fast pumping, to stir up dirt and pump it out. It's 
pretty disgusting how nasty that fluid can become after a few years. That's 
one more point in favor of DoT-5.

BTW, if you think flushing fresh fluid thru everything is more than you want 
to do, just flush the rear circuit, as that's the one that's connected to the 
mouth of the MC.
