I'm not a bean counter, but I know copper lines costs much more than
steel or plastic lines. That's why fuel lines are usually steel or
plastic.

PS: The entire American continent seems to be collectively convinced that
copper is useless for automotive use due to vibration induced
embrittlement. That simply is not so. In UK, it has always been very
common to use copper for brake lines for cars, with no ill effects.
Copper lines with a wall thickness and metallurgic treatment that makes it
suitable for the purpose, of course. If you like a stiffer but still
corrosion proof material, copper-nickel tubing is the way to go (which I
am also using myself).
