Fuel valve

Fuel valve
I've got what I suspect is a stuck fuel valve -- the one that switches the supply to the pump (not that the others are necessarily working, I just haven't tested them yet).
However, I'd like to know what the valve expects on input: does it need a constant 12 v to be 'switched' to one tank, or does it switch when 'pulsed' -- 12 V applied for a second or two causes a switch to the opposite tank from the current one? My test might have been invalid if it's the first one.
I plan to give it a good kerosene soak at any rate.
Thanks!

Callan,
Not sure about the soak in Kerosene, but I can tell you that the switch works like your former description. The valve draws from the left tank when there is no power applied. When +12v is sent to the valve, it draws from the right tank. As soon as +12v is disconnected, the valve goes back to the left tank. There must be a spring in there or something.
