Hello all, been a long time since I've been on here, hope everyone is well. A friend of mine picked up a well used '98, he pulled the seat and tank and found this line laying under it all. I tried looking on exploded diagrams and didn't see it and I don't feel like pulling mine apart to find it. It looks to be about 10in long and had a "T" cap on the end. If it was a vacuum or vent line I would expect it to be open on the end. Any ideas?
