ABSTRACT:
A fuel connector has a projection with a threaded external surface that mates with the threaded internal surface of a fuel injection valve fitting, and also has a sleeve surrounding the fitting. An O-ring engages the internal surface of the sleeve and the external surface of the fitting and allows the valve to be rotated relative to the connector without breaking the sealing engagement between the valve and the connector.
