I just did a zetec swap and I went and ordered a new line at the local parts store. It came with everything I needed to put it on. O-ring and everything. I found the most difficult thing to do when switching lines was getting the old line off the rack. Takes a lot of choice words and a pry bar for leverage and a hammer (also for leverage on the prybar). I think I paid 45ish bucks or something. You can get a much better price on rockauto.com, I just didn't want to wait to for shipping.
