Would anyone be able to tell me the size of the coolant return line banjo on the LNF, and it's comparative AN fitting? My coolant return line is leaking on my 20g and instead of making a custom hard line, I'd like to replace it with AN fittings and a steel braided line.

 

I think I found what I was looking for. 3/8ths or -6AN to banjo. Coolant banjo is m14x1.5.
