Best case: As jbn1 stated in his post: You have the piece and know the dimensions of both ends, Go to a good auto parts store and get same dimensioned fuel rated hose, and just install. Chances of finding a Vent line on a 1999, well, U know. And using pick a part to pull a piece of rubber been sitting out in the elements over 20 years, I would be wary of that part. But OP, do as U see fit.
