The car had stainless steel braided fuel line through out from the tank sump to the carb. Now installed all aluminum 1/2 line from the sump to the front inline filter and then from there had the special super lightweight Pro-lite hoses to the carb and it saved 7-1/4 lbs. Mind you, hand bending the 1/2 aluminum line to conform to the factory routing to be very neat was a nightmare on my hands and sanity, but I got it done. Pro-lite hose is pricey but feather weight and military spec strong.
