What Keith said. Also, consider using a flare brake line wrench, (they look
like a box-end with a slit in the side). When I had a persisent leak on a new
line, I could not get it tight enough to stop it until I bought and used one of
these wrenches. You can be FEARLESS in tightening the nut enough to stop the
leak, without rounding off or damaging the nut!
