I ordered some from Auto Zone. They only had half the lines in stock. I went to the dealership for the other. I intantly noticed a difference in quality. I purchased all the lines from the dealership and returned the Auto Zone parts. Also, I would spent the time protecting the lines where they rub. I found five or six places. I use rubber heater hose (sliced down the middle), silicone gasket sealer, and draw ties. I use gasket sealer to prevent any rubbing in the hard line. Lines should last almost forever.
