I removed the old line (which to me is the inferior design, as it has this weird turn in it - I have had to replace it twice) and installed the new line which does not have the sudden turn in it. Worked like a charm - the only thing I has to do was go out and buy a clamp for the upper connection, as mine was not reusable. I am hopeful this one will last longer than a year, as it is a better design in m opinion.
