From memory which sometimes is weak.:rofl:

Water pump heater hose port is usually a suction feed or return from heater core.
The pressure feed to heater core will come from intake water port.
Sometimes rear intake and can be on front on older intakes.

But to double check pull heater core hose that comes from intake and see if it is pumping water/coolant out end to heater core.
