The swivel end of the supplied hose is a -5 AN and the hole on the reservoir is a 1/8 npt so I needed a adapter for that as you see in the picture.(One end of the hose needs to be swivel so you can hook it all up properly.)
If I was to make a new hose, I would use -6 to 1/8 npt because nobody caries -5 stuff anymore, but for some reason my supplied line was -5.
