Great you got starter in and running..!!!

My solution for broken connector...
Used the old connectors drilled out base to secure this brass barb coupling.
If I can make do with an economical replacement thats as good or better....

 

Even better if you don't live in the northern ice country is eliminate that coolant line all together.

 

All good ideas. Biased, but like my solution best. My barbed connector was perfect length and had a larger ID than the brass stuff. Used 1ea stock removable clamp that was beefy and two of the largest in this pack on other side.
