The fuel and brake lines are the achiles heel of this car. I think water collects on them promoting rust.

I had your exact problem in my 90 Lesaber. The fuel lines were rusting out and leaking in multiple spots and the brake lines were equally a joke. Usually, the fix would be to splice in new sections of line. My problem was that there were no good sections of line to splice into. I elected to totally replace every line to the rear of the car.

GM actually has available the fuel and brake lines as a single repair kit (you just bolt it up, all the f+b lines are clipped together). Alternatively, part stores sell the brake and fuel lines in various lenghts that you cut to the right size. These parts are relatively cheap. The labor in the replacement is the killer: (9-10 hrs - done by a mechanic who knew what he was doing with a Lift. Expect it to take longer working under a car on your back.) My total bill topped out at $1100.
