The FI system has a fuel return line to
return unused fuel pumped to the engine back to the wing tank(s).

Is this dumb, or is there a good reason not to return fuel to the tank
whence it came, in this case, the ferry tank?

There would probably be a significant amount of under the cowling work that
would have to be done. So the good reason is cost.
