    Fuel fumes inside the hull are an explosion and fire risk. You really do want the fuel system to be well sealed inside the hull.

    There is no power ventilation fan/blower in a watercraft, so it is even more important that the hull not accumulate fuel vapors.

    As said, fuel vapor can be VERY dangerous. Also your fuel system needs to be under a small amount of pressure to work properly. ( 3psi or so).

    Do not use any sealer. You will have to probably make a new, rubber gasket.

    I should have been more specific, i wasnt saying this was fine and you should leave it and not fix it it was more of a nothing to worry about immediatly but you shouldnt be riding it until it fixed if that makes sense? Fuel vapors in a sealed hull is not a grand idea, but if its just sitting for now being worked on, shouldnt cause a horrible issue, keep the seat cracked open to allow those fumes to escape, and GET A GASKET!

    It may be as simple as just tightening down the screws for the sender a little more. If that doesn't do it, them remove the sender and inspect the gasket, and the sealing surfaces. You want it to be squeaky clean. That gasket should still be available from Polaris if you need it. Part number 5810858


    Just an extra note. Do NOT over tighten those screws. It doesn't take a lot of torque to get them to seal. If they are too tight it may actually distort the sealing surfaces and cause a leak.

    What is the availability on Polaris PWC parts these days? I got rid of my PRO1200 a couple years back, just curious if you can still get stuff pretty easy at dealers?

    I'm really close to Seebold Sports at Lake Ozarks, they were always pretty good at getting things for me.
