I don't see anywhere on that page that refer to hose routing. I'm sure my truck is set up as it always has been. Inner tap for the heater core is 5/8 and the outer one is 3/4.
But, tap on the water pump and thermostat housing are for 3/4 hose.
I did install an earlier heater control valve. Since they are easier to ffindfrom the parts suppliers.
