Mark,

No problem - no "confusion".  Could we say that a "pressurized old
Mazda/newer Ford" expansion tank fills both functions, "purge" and
"expansion"?

The picture you mention - was it of a long shiney box mounted fore & aft on
side of engine compartment?  It and your expansion tank are both
pressurized?  With the [air] "purge" function separated from the pressurized
"expansion tank", the "purge" box must be the equivalent of Lynn Hannover's
"swirl pot" that he's referred to many times.
