O.K., here's the deal. Parts diagrams are only a representation of the parts, the manufacturer is more interested in showing the parts and not necessarily where the part is or how a particular hose gets from point A to point B.
Here's what I would suggest, download a service manual for your ski, you can get one on this site for free if you join as a premium member or you can just google for one. As Doc. said in an earlier post the last two digits of the hull identification number is the year model, ie 99 and the model number should be on a sticker on the hull under the seat.
Also take a picture of the ski, and the hoses that you are referring to, this way we can tell exactly what you are talking about, otherwise I see no point in continuing this thread.
