First of all, you need to bleed the wheel furthest from the MC first, then work to the closest, the left front. With new lines, disconnect the lines and let them gravity drain until you get flow, with the cover off the MC. You could probably drain all 4 at the same time, reconnecting them as they start flowing fluid. Do that to all 4, then on to the bleeding procedure, always starting with the furthest wheel from the MC, the right rear and work to the nearest, the left front. As always when bleeding, ensure the MC doesn't run dry.
Also, make sure your bleeders on the front calipers are on top. If you have the calipers reversed, good chance they aren't. They'll never bleed if not at the top.
