Fuel Feed Line Size

[Roadbuster]

-6 / 3/8" is more than adequate for your setup. The previous engine in the Camaro was a 406 making more power and there were zero problems on-track.

Don't forget, GM used much larger engines than yours as factory builds with a 3/8" fuel line.



The main thing to be careful of is to use fittings that do not restrict the flow too much. Many -6AN fittings neck down to 1/4".

Thanks Carl! I was just looking up what was the inner diameter of AN fittings and you answered one of my questions.
