I recently installed ss lines, installing the right rear, when i took off factory one seemed like it was overtightened to begin, when installing new ss one i had a little trouble but got it, installed it, test drove, and looked at each line to make sure no leaks or anything, noticed real small leak from that fitting, its tight, i was wondering what size that fitting is on the hard line so i can get new one, then reflare it, or should i just reflare it and try?
