Minimum fuel line size for 347 with EFI

#1
Just a quick question here - interested in folk's opinion on minimum fuel line size for a mild-ish 347 running 8 stack/multi-port EFI. My current system is plumbed with AN-6 and it just looks a little small to me. Fuel pressure is in the 60psi range with twin pumps and a fuel pressure accumulator (not a swirl pot).

Don't want to starve my engine at WOT. AN-6 big enough??? Thanks in advance.
