Water Pump Inlet/Outlet

[sleepertime]

So just to clarify, the smaller port on the water pump closer to the engine side is the supply to the heater core, and the larger port on the pump, closer to the front of the car is the return from the core ?

Thanks, For the clarification. I am just about to start that process. I just got my taps for the pump to convert to the AN #10 beadlock fittings to match my vintage air fittings on the core.

yes, 5/8" port is rear closest to the heater core and is the feed to the heater and 3/4" port is on the radiator side return from heater.
