Fuel Lines?
 

I have a 1980 Camaro and i need to replace the fuel lines cause there all rusted. I need some insight in how to replace the lines. Should I go with the steel braided lines or just the regular steel tubing. This may sound like a stupid question but i'm kinda new at fixing a car up so any insight or suggestions would be much appreciated.

Steel lines from front to rear and side to side, where they mount to the body/frame. Beyond the frame mounts to the axles is where you use the rubber brake lines. The steel braided lines you are referring to are used in place of the stock style rubber hoses. They are more durable, and give stronger pressure to the brakes since they don't "swell out" under pressure like the rubber ones do.
