How To Fix Brake, Clutch, & Fuel Lines

This repair was performed on a 1992 Mitsubishi 3000GT, and this video will show you how to fix and resolve a situation where a flare nut has rust seized onto a hydraulic line and the nut edges had rounded when attempting to remove it. Nothing worked to remove the nut (i.e. penetrating oil, wiggling the line (to brake the rust adhesion) and a crowfoot tool to twist off the nut. The nut was cut off the line using a small rotary metal cut off disc. A new replacement line with attached flare nuts was purchased from a local auto parts store along with a brass compression fitting (or coupler to join the cut lines) and a tube bending tool. The replacement line was bent and cut to an approximate length then joined to the cut off hydraulic lines via the compression fitting. To make square cuts on the lines, a tube cutting tool was used in lieu of the rotary cut off disc. The line ends were than chamfered (to open up the interior of the line) and deburred (so that the compression fitting collar would fit).

Perfect, Im in the process of doing the same thing on a gt as well, I have to cut my line too. Your vid is really helpful

That compression fitting is fine for hydraulic clutch lines but DO NOT USE ANY WHERE ON YOUR STEEL BRAKE LINES!!!!!!!!!.

Do know what size the tubing is ?

I just matched it up with what was available at my local Advance Auto store. They also had the pressure fittings.
