Greg,
In the article, on the right side by the pictures, it sais;
"Eventhough our project '67 Mustang is making over 500 horsepower at the wheels, it is running out of fuel due to the factory 5/16" fuel line (left.) We're upgrading to 1/2" (right), which will provide a nearly 150% increase in area. A rule of thumb; 5/16" (-5AN) will support up to 300 horsepower, 3/8" (-6AN) will cover up to 500 HP, and 1/2" (-8AN) is good to 700HP."

Those HP numbers are at the wheels right,... so the "3/8" (-6AN) will cover up to 500 hp", is at the wheels, and should be good well up over 600 HP at the motor,... right?

This is probably one of those things were you could ask lot's of people the same question and have many answers. I'm sort of leaning toward the views of the performance minded. I'd rather be safe with a system that's a bit overkill.

On the other side of the coin I guess if people want to run a 16,000 dollar engine with a 3/8 inch paper element fuel filter and cast 90 degree 6AN bends that's cool. It probably works fine for most people.

Here's a good read.
