    STX 15F Pulled gasket/o'ring out of fuel tank?????

    I was adding some fuel via a gas can to my STX-15F and when I removed the filler hose from the gas tank it appears to have pulled out some sort of gasket or o'ring from inside the tank.

    I can see where something like this may be needed for sealing the cap but the safety chain prevent this from seating directly beneath the cap. I also cannot see how it would just rest inside the tank on top of something as that won't seal anything.

    Anyone know what may be going on?

    Here is what I think the part is on the diagram and also an image I just took. In this image, I have placed the gasket inside the safety chain where I think it may actually do some good. But now that I have seen how deformed it is, I am just going to remove it until I can figure out where it came from.

    Maybe a fellow owner can check their gas tank and see what is visible?

    Can't tell from your picture if it's there but there is an o ring that seats on the inside rim of the gas cap. Possibly out of that area???
