Water pump/radiator install questions

::
96 Classic 4.0/ AW4/ NP231 Stock.
Water pump: Bought the dorman inlet tube which is an exact replica of original as far as I can tell. It came with thread sealer already applied. I installed the tube to line up with the heater hose and stopped when I didn't think I could get another full turn..but it still moves a bit. Leak potential?

Radiator: Teflon tape OK on tranny line bungs into radiator? Also, on the top line, do I need to seal the line to bung collar threads since it's a flare fitting?

Thanks in advance

If the inlet tube 'jiggles' at all, it will leak. No other choice but to give it another full turn. (This is a bad design, in my opinion.)

No need to use sealant on a flare fitting, as the seal is at the flare and not at the threads.
