The copper/nickel brake line is easy to work with, if you want to make smooth consistent bends you can pick up an inexpensive tri-bender, if you use the correct size tubing from your local FLAPS, it should have the correct inverted flare nut on both ends, you can cut one end off and use the pre-flared end to start at the tank.
