Ford had a recall on that problem. Can't remember if your truck was affected. They put an anti-return valve on the supply line of the fuel pump. Best bet is that the
front fuel pump front fuel pump
is bad. The switch valve just turns on one pump or the other. There is nothing between, unless the pump is faulty.

Maybe this will help,
Generally when drawing from one tank causes the return fuel to go to the other tank , the problem is with the tank that is overfilling and in this case as just about everyone here gathered The problem is with the overfilling tank fuel pump, Check valve !

I'm not sure which fuel pump you reused. Presently , if you are getting fuel placed back in the rear tank when using the truck on the front tank, that fuel pump in the rear tank is defective.
