I found 6mm brake line from Performance tool and supply in Bradford, PA number is (814) 362-3221. I guess he's a dealer for
www.FMSIinc.com - Automotive Hardware - Repair Hardware, Fuel Lines, Brake Lines, Air Conditioning I called them and the give me his name and number. I bought A 20 and 30 inch piece and the union with shipping was less then $19.00 I bought an OTC brand flairing kit locally for $20 My problem seems like yours . It broke at the nut just next to the rear rubber line I used the 20 inch piece screwed right into the rubber hose. Which was long enough to get to good metal line. Now I have an extra piece of line. He sells the OTC bubble flair kit for like $23.
