    Choose your fuel carefully

    Rather embarrased to say this is from my 12f, put it into storage in my garage last year with a fresh tank of 93 from a station away from the water and was greeted with this when the ski wouldnt start. The pump, and regulator are done as well as the can. I am currently working on a stainless or aluminun replacement lower insert if anyone wants one.

    Those are some nasty Pics there Sean. Did you have any Fuel Stabilizer in the Tank as well . . . or just fresh gas? JB

    No just fresh 93. I have never had much luck with the stabil but my winter season is also just from late November to February. Bad gas is an understatement.

    With or without ethanol in the gasoline?

    Perhaps the better practice with ethanol laced gasoline is to store with the fuel tank drained completely dry or holding as little ethanol blended fuel as possible. The old guide of storing with a full fuel tank was before ethanol became widespread.

    Some fuel stabilizer products can help manage moisture triggered phase separation in ethanol blended fuel but cannot overcome excessive water. Draining the tank reduces how much water can be left in the tank because the ethanol takes water with it when you drain.

    I used to store my watercraft with full tanks, now I lean towards bone dry fuel tanks during storage, especially if there is ethanol in the fuel.

    Dry tanks or 1 gallon of ethanol free will by my new practice. I need to use my flex fuel sensor to test the ethanol content of that tank. Usually around houston it hovers right at 7%, ill bet this one had more.

    The 2011 300X Service Manual says to drain the Fuel Tank for storage...

    Does that sensor compensate for water in the fuel?

    Once phase separation begins the ethanol drops out of the fuel and collects in the bottom of the tank with the water. So the remaining gasoline above has less ethanol.

    I am actually not sure. Its a stock gm flex fuel sensor. Its on my 15f not this Ski. My fuel gauge will actually warn if water is in the fuel past a certain percent.
