Bulent, I'm familiar with the Cozy, and I think that you will either need a more
complicated fuel selector valve (double valve for return fuel), or a sump tank
for returning the fuel. The sump tank has to be large enough volume to prevent
the fuel from overheating (probably about 2 gallons). My Velocity has no fuel
selector as both wing tanks feed a 3 gal. sump tank inside the cabin.
