I can't see how you could damage the motor in the valve.
It's a DC motor that spins different directions based on the polarity of terminals D & E.
The Dual Tank Theory of operation writeup may help clear things up for you. You have the 81-91 system in post #2.

Is there any harm in using a different switch? I just redid my entire fuel system, converting from the old style selector valve to the new style. But the switch i used has no OFF position, it’s ON-ON. I’m guessing the difference is that instead of the new valve only being powered for a second or so during switching, my valve is always getting power. Is that a bad thing?
