6.4/8hp70 project 67 Barracuda

questions:

1. for those that did not use the hemi coolant reservoir, what did you do with the heater hose that has the "T" going to the reservoir?
2. what is that small hose purpose? (hoses', hoes, hose's)

I did order an oem radiator and fan for a 6.4, but also got an inline filler neck in case I need to use it instead of the oem reservoir.
