More ideas for your individual evaluation.

The fewer parts, the better!   Don't use flapper valves in wing tanks,
 that is one more part to malfunction..  Instead, use 1/2 inch pvc (thin)
pipe sealed to but through the bottom of the second rib and running
along the bottom skin inboard to about 1/2 inch short of the first rib.
More than one tube will probably be required.  I think Glass air does
this, but it will work on metal tanks, too.  Depending on how full the
tank is, in uncoordinated flight, a lot of fuel will be trapped where you
want it.

Always slip fuel side up!!!!!

Can't always do that Bob. Can't see the runway so well sliping
to the right in a left hand pattern with a high wing airplane. 
I will have to try that the next chance I get. There is also a real 
problem with forward slips in cross winds. You have no choice. Sideways 
slips might be a problem too. Best to fix your fuel system so it can
handle slips without thinking about it. PL

Follow the rules, learn how to plan your flight so that you have at least
30 minutes fuel remaining when you land!  Its the law!

And I think Vance Hearn's system is as simple as it gets, even if he has
to add check valves to prevent cross flow when parked.  Finally found
someone I agreed with!
