I planned on replacing the hard line with a chunk of rubber hose as well, but since the connector on the purge valve was broken on mine, I had to get another one of those, and for the princely sum of $1 at the you pull it place, and 5 minutes of walking and 2 minutes of pulling it (had to gawk at a few before I found one I wanted), I just got the whole thing. I could have pocketed just the purge valve end, and I am sure I have emissions rated hose that size, but figure I would do it right.
