copper line will harden after time. if you need to get it a bit softer (more flexible)just heat it good and hot(red) with a torch and let it cool. it's much easier to bend then.DON'T use for fuel or brakes.
I have copper lines on mine and you never have to woryy about a plastic line breking or ripping. The only bad thing it that they tend to rattle at times depending if your ride is bumpy or rough.
is there anything you can do to make the copper line look... well... not so copper. like paint it or something? i like hard line but every time i see it on a truck i think of my bathroom sink.
Anybody used the flexable copper line before? Can it handle the same pressure, and what about heating the ends of the copper line and sodering them as you would a hot water heater. Any thoughts on this technique
