Weird, I thought it was an 8. I ran all 8AN lines/fittings with mine.
-8 is 1/2" James ,-6 is 3/8" which is the stock fuel line size.
For the guys who are unfamiliar with dash fuel line sizing,each dash size relates to a 1/16".
These are some of the common dash numbers used for fuel/hydraulic line sizing. Odd dash number sizing isn't all that common in the automotive or hydraulic line sizing world. If you need bigger then -16,odds are you already know all about dash line sizing
IE: -3 is 3/16"
-4 is 4/16" (1/4")
-6 is 6/16" (3/8")
-8 is 8/16" (1/2")
-10 is 10/16" (5/8")
-12 is 12/16" (3/4")
-14 is 14/16" (7/8")
-16 is 16/16" (1") etc.
