1. Yes I would want the high level sensor to close the LPFS to prevent overfilling.
The tank is vented to atmosphere via a vent line exiting the bottom of the
fuselage.
2. There is only want jet pump mounted in the cockpit with both wings feeding into
it
3. The possibility exists for the tanks to feed unevenly. It is my understanding
that if one tank is dry it would still feed from the other tank. If not then
that tanks transfer switch could be placed in off with the other side in Manual
or Auto which should close the LPFS for the empty tank.
In the event of electrical failure all solenoids open since they are NO which would
over fill the main tank to the point of venting but allow the main tank to
remain full until all wing fuel is gone giving you time to land before fuel
exhaustion
