rear of the tank is that in the event of a serious engine room fire which
consumed the fuel flexible hoses, the unvalved return line could feed the entire
tank contents into the fire. With the high level return this will not happen ,
unless you are in an unusual attitude. So this is what I have done.

That's why I put a check valve in the fuel return line, which prevents fuel from
flowing back to the engine. I also put bleeding check valves in the vent lines,
that will avoid the spilling of fuel through the vent openings in case of
an accident with the airplane lying on its back or on the side.
