Here are pics of the replacement line. The existing nut was stripped (by the previous owner) and it would not tighten properly and dripped.

I used a scratch awl to open up the end of the tubing, and a file and some sandpaper to round the ends where it was cut / squeezed / crimped / out-of-round.

Works good now.
