From my experience the fitting locks towards the inner part of the hole because the cooler line hole is tapered like a pipe fitting.




This makes no sense. Pipe threads are tapered. The male and female portions are tapered if I recall correctly. That means they tighten along the whole length of the mating surface.

If is the cooler fitting in the rear be VERY CAREFUL NOT TO CRACK THE CASE there is not much material back there.




This is the front fitting.


I just got back from a small tool shop that had straight flute extractors. I'll get to work on it this afternoon.


We are brothers and sisters doing time on the planet for better or worse. I'll take the better, if you don't mind.
