    Ultra 150 leaking fuel - thoughts?

    I just brought my 99 Ultra 150 out for the season and noticed fuel leaking out from the handlebar area and running down by the glove box.
    Seems really odd to me that fuel would be leaking from up that high. Any thoughts on what I should look for? Busted/cracked fuel lines? If so, are they easy enough to change myself? Any step by step instructions needed???
    Thanks

    Your fuel tank check valve has failed.
    Follow the lines coming from the tank, you will see one with a white checkvalve in it and the line continues up to the handle bars.
    You can take it out, take it to an autoparts store and ask for a check valve, they will look in stock and find one wit the same size nipples
    Far cheaper than a new Kawi one
    To test it, air should be allowed into the tank and not out.
    Expansion of the fuel due to a hot engine compartment is forcing the fuel out the vent and onto the glove box.

    Thank you. I'm going to look at that today.
