I see, that would work since you're mindful of the overheat possibilities. You could power the pump directly with a 12 volt battery provided you knew which wires to connect to.
Looks like to me disconnecting the +/- from PUMP1 connections and putting those wires to 12volts would power the pump no? 12volts to the pump wires, not the fc3 controller.
applying +/- power to the remote side is basically what the car does when it's running, but I'd disconnect the car from the controller if you're going to apply power to the controller connections. All that fc3 controller is is a 3 relay board transferring high current from the battery to pump 1-3
