i don't think that is it....
that boss attaches to a hose and it is above the pump, liek right in the middle, not bellow it where that longer metal tube is
also, it says to use an o-ring for that pipe, and i plan to get the pipe, but i don't know anything about the o-ring for it....

If I still remember right that insert is threaded. It may be better to buy a new insert as well as the heater output tube that I posted a picture of, it is a common leakage problem.
If I remember right you asked how to drain the system. The lower left side of the radiator has a drain valve. Unscrew then it drains.
