I just got finished fixing a nagging air leak at my right side glad hand. I cut out the kinked spaghetti/pretzel plumbing the guys who bobbed my Deuce left behind. I hole drilled a frame brace (one inch hole saw) and used 3/8" soft copper with a spring bender and compression fittings. A simple J shape. It looks much cleaner now and the air leak is history. Went on a twisty two lane 20 mile drive to celebrate. Brutus performed splendidly. Got up to 48 MPH.
