What size is the STS oil return line?

I am moving my STS oil return line to the oil pan. I will shorten it and use an Earl's fitting to connect to my 1/4 NPT fitting in the pan. What size is the line, -6AN or -8AN?
I am looking in particular at -6AN part Earl's Performance 820106ERL or -8AN part Earl's Performance 820107ERL .
Thanks in advance.

As you know, the STS return oil line is 3/8". I am in the middle of a DIY rear mount and I am use -8 from the turbo to the pump and -6 from the pump to the pan..

No, I did not know, hence the question. My fitting on the pan has a 1/4 NPT female connection. What fitting would I put on the 3/8" STS line?
