The only copper line left on mine is the scavenge tube. I see no need for copper fuel lines in this day of high quality "rubber" hoses. I trust hose clamps more than compression fittings. I think copper fuel lines are descended from the era when hoses were actual rubber, which was hard to get then and dried out and cracked over time. Possibly during WW2, when Universal was producing the Utility 4 for lifeboats, the military preferred copper lines because hoses could puncture and burn from enemy fire, but now that isn't a problem, except maybe in Ukraine, bless them. Besides, if you have a fire anywhere near a carburetor, you are screwed anyway.
