Braided stainless dummy

All these years and I never worked with braided stainless, and I know NOTHING.

So I need to run stainless from a 3/8 in factory type fuel pick up at the tank, to the fuel pump(Edelbrock mechanical) which has 3/8NPT fittings.

I THINK I'm stuck using 6AN line due to the 3/8 diameter pick up. I really wanted to go with 8AN if possible.

What fittings and such do I need? The Summit catalog just confuses the hell outta me.:sad2:
