How about using a siphon breaker chamber in the vent lines to preclude
pulling fuel out of tanks with a inverted U shaped vent line.

I copied a neat idea from the Velocity.  My three vent lines combine
into one, which tee's off to a plastic auto PCV valve located on my
rear firewall.   The PCV valve is a 90 deg unit, mounted facing down,
and acts as a check valve, admitting air if the external vent is
blocked, and admitting air to break any siphon, as well as preventing
a fuel spill in a turn over.

I always love those ideas. Thanks George for sharing that with us.
There is a lot of car tech out there that can be used.
