How important is it to replace this when installing a new clutch. I've heard that the stock (Rubber) line can cause poor engagement and leads to the flywheel getting "glazed". I'm not sure what that means, but I'd like to hear people's opinions.

 

I replaced mine. It took FOREVER!!! the rear bolt that allows fluid through the line is a royal PITA. However the clutch does feel better.

 

I have one, and i'd never do it again. Pain in the *** and no reward.

 

i agree its definately not easy just because of the back bolt......but with the line and the restrictor pill out it engages a lot better
