Just curious. Why do you need a 1/2" line to feed your engine? 600HP, 600CID? I only have a 535HP and it runs just fine with a 3/8". I'm not trying to be offensive, just asking. I put the braided line on my 68 Norton Cammando from the tank to the carb, it worked perfectly for 30 years untill I rebuild. It sat outside in the sun most of it's life. Didn't have ethanol then though.
