I'm a fan of getting a steel brake line with inverted flare fittings at the car parts store, borrowing the pipe bender tool and flare tool that they loan out for free, and make a new all metal line. I am also a fan of these copper flare gaskets, because they make the flare fitting seal very well without having to torque very hard on the fitting.
More of my ramblings about the darned fuel line and fittings:
