That looks like the tamper collar that comes on the fuel screw. That o-ring however, not sure what that is about. The o-ring that is on the fuel screw is much smaller and it is in a groove on the fuel screw, inside the AFC housing. Some people tear it when the fuel screw stops and they try turning it more.
You are good to go
