Two stopcock valves, one on each tank and then a 4 way stopcock valve which would let you choose tank A or B or both on or both off.

Most systems will not let you draw out of both tanks. Your fuel pump will draw out of the tank of least resistance and then suck it dry. Then you think something is wrong and look for the problem...which is you are out of gas on one tank.
Ask me how I know
FWIW:
# Three-Way Valves connect two permanent tanks to a single motor.
# Four-Way Valves connect three permanent tanks to a single motor.
