Well if you have a problem with breaking the copper line, then try this: Get a piece of rubber fuel line or vacuum tubing that will just fit over the copper line then slide it over the copper line and then you should be able to bend the coil spring shape in the line to reduce shock in the line without kinking it. Then just place your fittings on the ends of the copper tubing and hook it up. The rubber hose will absorb the vibrations and keep the line from breaking. I have have had mine on my GMC for 14 years with it setup that way and have never had a problem.
