Since both tanks share the same vent system, the pressure across both tanks should remain the same.  And my theory is that returning fuel from the engine won't run into the aux tank because the transfer pump (even when switched off) will act more or less as a check valve.

Coincidentally, there is a new thread on the Syncro list where someone is asking for assistance to install one. In the meantime, I had sent a message to Ian regarding another possible group purchase. Perfect opportunity to discuss all these matters at the same time.
