Here is one possibility based on a Broward and a Hargrave designed Cheoy Lee.

All of the fuel return lines are attached to a unvalved manifold that dumps into the deck side of the Fuel Fill Manifold. The fill valve on the Fuel Fill Manifold for the tank in use MUST be open to allow the fuel to return to the supply tank.
If all of the fill valves are closed, the fill manifold will pressurize between the valve and the deck fiting and will most likely burst a hose or damage the injector pump
If the wrong valve is open, the fuel will feed form one tank and retun to another, eventually overfilling that tank and dumping over the side through the vent.

In other words, if you are using the center tank as your fuel supply source, the center tank fill valve on the Fuel Fill Manifold must be open as well.

Hope this helps.
