I'd advise you check into that application of copper. Copper work hardens and cracks from vibration - that's why copper fuel lines on cars got phased out about 100 years ago. If you want the fuel line armoured, consider stainless braided hose or at least a braided stainless sheath over your conventional hose.
I, myself, personally intend to continue being outspoken and opinionated, intolerant of all fanatics, fools and ignoramuses, deeply suspicious of all those who have "found the answer" and on my bad days, downright rude.
