NAPA will have the brake line in multiple lengths. Get a little longer then needed, the bends will use up some length. Get the bottom tool in your list, it will do everything you need for a one time use tool. I would stay away from compression fittings on fuel lines, I know a lot of guys do it and get leak free results, but NHRA and other racing associations ban them. I figure if they don't want them, neither do I.
NAPA also sells a greenish/gray line that can be bent with your hands. Its pretty fool proof and kink free. If you can stand the color, its a good way to go.
When you go buy some line, buy a extra piece for practice. It takes a time or two to figure out where to start the bend so it ends at the right distance from where you started. You will also note that the line has a weld seem on it, use that as a reference guide so you know which way the bends should be going from one another.
Start at the carburetor and work down toward the fuel pump. If you have extra line or miss the turn a little, you can correct it and have it not show to much. A mistake at the carb will be obvious since its the first thing you see.
