Working on a friends challenger with a 572 all aluminum hemi making 805 hp at the crank. I am going to run -10 feed and -8 return for the fuel supply. Currently the car will be set-up on carbs but will eventually be converted to EFI. Question is, what should I use for fuel line? I'd prefer .028 wall stainless but is that practical for a fuel line that is 5/8"? What do you guys recommend and or use yourselves? I do NOT want to use braided stainless lines. Thanks in advance!
