If you get a line kit, they will already be made up, ready to install.
Here's something that you may try before you strat tearing into the system too much, fill the master Cylider, then try pumping the pedal gently, rather than just pushing it down. See if it builds up any pressure. Could be that the system is dry and needs bled, but it may take a bit to get fluid down to the wheel cylinders. Also, this will allow you to see any potential leaks in the system.
