So just getting into jet skis this year i recently picked up a 87 js550 FOR $300 runs like a charm, and i also picked up 93 750ss i was just wondering if the fuel and oil lines need to be primed b4 running the engine. I had the engine started but its not getting fuel from the tank, is there a fuel pump on these things? lol im used to dirtbikes where gravity does the job. So ne one who has ne pointers it would be greatly appreciated.
