I would recommend buying a new line, this way you are sure it will not leak again. I would then fill the system with nitrogen to check for leaks before you pull a vacuum. A vacuum is essential if you want the system to be free of air and moisture. This will insure your system is operating properly. If you have a set of guages, you will need to pull a vacuum of 28". After you reach 28" of vacuum shut the guage off and make sure the system holds the 28" (just another way to check for very small leaks). Before you charge the system make sure you bleed the air out of the middle hose on the guage or you will have defeated the whole purpose of pulling a vacuum. Any other question PM me.
