As the title states. I'm assuming I can pull coolant from the intake, but where should I return it? There is no port on the rad, and returning to the intake seems like asking for an air lock.

What is your reason for running an electric water pump?

Pull it off the intake to supply the heater core and crap it out to the water tank of the radiator on the side that supplies the engine or if there's a fitting, put it on the suction of the water pump. Anything else on the pressure side of the water pump would be a waste of time IMO because it will be at pretty much the same pressure anywhere on that intake. Which = no flow through the heater core. Maybe by convection, but that'd be about it. May not turn over the hot water fast enough to keep it from cooling off.

I agree....a race car with a heater??? That's seemingly dumb, but oh well.
