Fuel cap gasket

I bought an used ATV and one of the things it was missing was the rubber gasket for inside the gas cap. As a result fuel would sometimes seep out from under the gas cap and down the side of the fuel tank causing a mess. I designed up a gasket real quick in Fusion 360 that fits perfectly for me. The three ears on the gasket are so the gasket will engage the threads on the fuel cap and stay in place. The little column in the centre is so you have a way to properly screw (and unscrew if required) the gasket from the fuel cap.

I chose TPU for a few reasons.
-It is a semi-flex and it should provide a good seal
-It is fuel proof
-I had it on hand

This gasket was made for my Polaris ATV, it should fit most Polaris vehicles
