AN fitting question for fuel line

I'm installing a stand alone fuel pressure regulator and was wondering if I should use an AN6 or AN8 fitting for the fuel line? Note the other end is a NPT 1/8.
Thx.

-8 is fine, you really don't need to go larger than that.

If I'm not mistaken, -8AN inside diameter at it's smallest is 3/16, or 9mm. -6AN is 1/4 or 6mm. Since NPT is measured on inside diameter, i would use -6AN.
