96 Sea-Doo GTX 787... I bought this over the summer as a project, I bought an engine from SBT great people!!! I finally got around to putting the engine in, and I have one thing I can't figure out so far, there is a vacuum line coming from the rear of the ski that I can't figure out where the hell it goes??? Everything else seems to be hooked up and I can't find a spot for that??? I have a picture I will try to post with it!!! And help would be awesome Bc I wanted to attempt to fire it up tonight
