-6AN or -8AN

Hello all knowing Forum, I want to replace my fuel feed from the stock pump up to the carb. Planning to buy a dual feed setup for my 670cfm Street Avenger (Holley 4150 style) and some stainless flex hose. Do I want -6AN or -8AN hose and feed line?

Currenlty running a stock ZZ4 w/ a .373 and TH350 but planning to convert to a 5-Speed.

Thanks.

3/8" is all I'm looking for. No reason to build it any larger.

I should have looked for a conversion chart and answered my own question...

Thanks Matt.

I concur.
I'm running 6 AN dual feed set up on my Holley 650.
-6 AN = 3/8 hard line.
