The new sleeve has an oversized outside diameter, which does not allow the injector sleeve to fit the standard bore. The oversized sleeve will have an added ring that is located around the middle of the insert for identification. Also, the new sleeve will require a larger bottom O-ring. Refer to Illustration 1.
