Inlet Heat Hose

I need some help locating the inlet heater hose on my 2006 3.3L Sonata to install a flushing T. I have located the two hoses labeled inlet and outlet, the part number on the outlet hose is 97312-3K100. The part description in the shop manual says water pump outlet hose, so I'm wondering if this is the same as the heater outlet or if they are reversed. Does anyone have any experience with this? Do I just install the flushing T into the hose labeled inlet as common sense would dictate?

Thanks!
