AN Power Steering Hose

You know how to silver braze? In other words high temp silver alloy? If you can get a "stub" steel line that fits the box or pump, you can braze a JIC adapter onto it. We used to do this all the time at the old parts store. Depending on how they are made, sometimes a JIC male plug works, you can screw it into an appropriate fitting if necessary and get it into a drill press vise, then drill it for a passage and then drill larger to form an entrance and shoulder for the tube. Clean them up, flux them, and silver braze together.
