So the valve on the opposite tank stops the flow if the selector valve leaks a little. The selector valve only allows flow from one side or the other at any one time as long as it is fully in the detent. My Facet pumps are operated independently, usually one at a time as intended. There is documentation that the Facet pumps do allow fuel flow in the backwards direction when not operating. If anything, the check valves are overkill but Chris himself drew it up for me. And Fred Hulen, or was it Hinde, anyway the fluid design engineer on this list agreed. Anyway, it seems to work for me.
