The braided line is so cheap its not even worth worrying about the cost, just replace it. If your leak continues (and I think it will) I would suggest removing all 6 injectors and having them cleaned and refurbished. They're 20 years old now.

Also, check that all the clips that secure that injector line to the engine are in good order - on older cars you find that they're brittle and broken, or missing completely. This allows the line to vibrate more than it should, which eventually increases the chance of leakage around the connectors.
