The stainless steel lines are not as soft as steel lines, requiring the progressive form-fitting of multiple tightening-loosening-tightening routine mentioned by Chuck above.
After you do this to one or two fittings, you will get a feel for it and it is easy to do. BTW, I do this same procedure with steel lines to make sure that I don't have any leaks.
The pre-bent stainless lines from Inline are as close to exact fit as you can get, and you will never have to worry about your brake lines ever again.
