Hello Brian!
As ever, you are absolutely correct. My bad. I know better than to use
absolutes, especially with this crowd1
On the other hand, the systems you've cited feed from the mains to a header
tank at the low point. This arrangement should preclude drawing air from
the empty tank. In my RV, the fuel pick up in the tank is the low point in
the system. It's all uphill from there, and there is no header tank to
buffer the system. To the best of my knowledge, and I cringe as I type the
words, there are no certified, low wing singles that will feed
simultaneously from multiple tanks other than those equipped with headers.
As a point of interest, does anybody out there know of a plane configured
that way?

Well, it is probably not safe to use the words "always", "never", and
"only" when describing systems. As I pointed out earlier, both the
Nanchang CJ6A and Yak-52 are low-wing aircraft that have only an on/off
fuel selector at the firewall. There is no way on either of these
aircraft to select a left or right tank. They are always on "both".
