99 Buick century recharge line install. I couldn't figure out how to remove the punchered line so I cut it in half ,now I'm trying to get the new one in around the break lines and booster, but I'm stuck tried underneath, through the fender well, uptop. Do I have to remove all the break lines and booster to get it in?

It may be helpful to just cut the good section of line off the good hose with a pipe cutter and splice it onto the new line. I have used these a few times to repair the long lines on Tahoe'* and Yukon'* that run to the back with good success.

Also is it the high pressure line or the low pressure line? I can look up the repair procedure.
Hope this helps.

That'* a cool thing, never thought of looking for such a thing before. Thanks carnau!

carnau'* suggestion could really help. Another idea, maybe there'* enough room to take the master cylinder off of the booster and pass the line between the two . . . ?

Hope this helps, please let us know how it goes.
