I was think about that also. However, if you are on the low side of
fuel and then make a turn, the fuel on the inboard stake would rush to
the end. Would that not introduce air into the sump tank that you would
have no way of relieving because you have the vent blocked off?
The result may simply be fuel draining from the high side tank to the
low side; however under high power the fuel demand to the engine may be
greater than the gravity feed rate from the high-side tank, resulting in
air being drawn from the other.
. I have a theory that the vent line to the sump tank causes more
problems than it solves, once the initial "burp" of air is allowed to
escape from the sump tank (before engine start).
I'd be interesting in hearing what problems the sump vent might cause.
