If the oil line is leaking between the metal section and the flex section, the line is bad. I doubt seriously it can be fixed since that's a crimped connection. If you take the line to a shop that makes hydraulic lines/hoses, they may be able to throw another crimp on it, if not, they may be able to rebuild the line with some fresh parts - or replicate the whole darn thing. Double check what the price of a new line is from Suzuki before you go so you can make a cost effective decision.
