Line can stay, just keep in mind you may need to transfer the oring on the end out of your old slave as it goes in the tip of the line and it sometimes (usually I believe) ends up staying in the old slave when you remove the lineSorry to bump an old thread, but hoped someone could give some related advice. I'm doing a clutch job on my 2012 and have ordered most of the same items above - I received the new slave cylinder, but noticed it didn't come with a new hydraulic line. Should the old hydraulic line be replaced as well, or can that stay?
Thanks for the help!
