I am asking because I searched and can’t find the thread I once saw here. There was a guy who had made his own metal lines and ordered some 9m x 1.0 fitting on line somewhere for 70’s FJ40. As I recall he said they were not deep enough and didnt seat. So my question is: does anyone know if the steel metric brake line fittings have to be a certain length? Trying to repair existing ends. I do know about the Napa adapters, trying to keep from wasting money if standard fittings are too short. The ones I have found show to be 14mm long
