Fuel Line & Return Line Sizes

Can I ask what size fuel lines people recommend and with what return line?

I have seen articles that suggest the return should be smaller than the feed, but when looking at the following Mallory document, http://static.summitracing.com/globa...s/maa-4309.pdf, it suggests that the return line should be the same size or even bigger.

Re: Fuel Line & Return Line Sizes

Depends, how much HP and whether it's carb or EFI.

The only one I know because that's what I'm running is EFI up to 500 HP. It runs -6 AN feed and return.
