The fact that only some of the really old cars, and some British cars, had copper fuel lines could easily be accounted for by the mere cost of the copper. If there was a good reason not to use copper, it would have to be because it either: 1) did something to the fuel, or 2) didn't last and caused a leak. I have occasionally read a thread where someone claimed copper chemically reacted with gasoline to make it poorer; others say that's crap. I've also read where some claim that the heat characteristics of copper tend to vaporize the fuel; again others say that's crap. The "copper lines don't last when jiggled" argument would seem to have merit, maybe; but then why do they sell them at an additional cost and why are there threads advocating their use for oil pressure lines (on this forum as well) -- even saying that they hold up better than other lines? The fact that high-end boats and yachts use them as OEM is undisputed (but you can still find the occasional post even on those threads where somebody says "don't use copper fuel lines"). They even tout their "color coded copper fuel lines." Now, I don't have copper fuel lines and have no intention of putting them in, but just saying they're bad, don't use them, they've weren't used as OEM (nor are gold-plated contacts), and "I've always heard you shouldn't do it" just begs for some supporting facts. Even if they're not sanctioned or approved, you might ask "why?"
