I have a 93 seadoo xp wasn't running right like it was a carb issue. Rebuilt them both and then discovered a gas leak. I fixed that and replaced all the fuel lines while i was at it. now i have no gas getting to my carbs ski will run great if you put mixed gas into the carbs but dies out when it is gone any ideas. Is there a Fuel pump or Fuel filter in these skies that could be clogged?
