Re: 92 Seadoo xp
sea doo fuel lined disolve from fuel addatives and crud up the entire fuel system, I always replace them with heavy wall vinly tubing that is clear and allows you to see what is going on it the fuel system, the lines are inexpensive and they do get loose if you use cable ties to secure them , so I use a larger hose over the ends to make it twice as thick where it clamps and use metal hose clamps to secure the ends this works fine,, I also learned that anyplace the hoses are close to the engine or exhaust system they should be insulated by sliding some black plastic wire loom over them to keep the fuel from heating up and vaporlocking, next I place a restrictor in the return line from the carbs to the fuel tank, I use a tiny egg sinker that has a hole through the center I heat the vinyl line and insert it in, right by the carbs, this keeps fuel preasure to the carbs and lets any air that may be it the system go past and bleed off in the tank, I had a engine that liked to stall when accelerating from a dead stop , I watched the clear lines to see why, there was air bubbles in the line and that lead me to a loose clamp in the fuel system on the suction side, once I found the air leak and tightened the clamp the engine ran fine, . I never leave sea doo fuel lines on a ski as they will always foul up the carbs and fuel switch.
