I would like to get some idea, what is the best way to build the fuel
return system of the 13b in a Cozy. Per plans we have two tanks with
fuel selector valve. I have my own ideas, but would like to hear from
some people with more experience.
How to prevent one tank from over filling by the return fuel, without
having a complicated pilot managed fuel system?

The certified aircraft that I am familiar with deal with this in a very
simple and straightforward way.  All return fuel is directed all the
time to one of the mains.  THe SOP is to always start, taxi, take off
and climb on the "returned to" tank.   After it is burned down a
reasonable amount (you decide), you can switch to any other
tanks that you might have, and will be adding a bit of fuel to the
"returned to" tank.
Keeps it simple, no super expensive valves and an easy SOP
gets you safety without having to worry too much about exactly
what is going where.
