quick question on stainless braided lines. i have been searching around the net for all my oil and fuel lines i am going to be getting. i am planning on getting -10an and -6an lines for my setup. however, i have noticed that you can get 3/8" or 1/2" line alot cheaper. why does it state "not to be used with AN style fittings"? so, is it not even worth trying to adapt everything to work?
