Abstract
A fluid coupling for a fuel system in a direct injection internal combustion engine having a body with a ball portion and a fluid passageway extending through the ball portion. The body also includes external threads which extend concentrically around the ball. A tube has an outwardly flared end while both a ferrule and a nut are disposed over the tube. The nut includes internal threads which threadably engage the external threads on the body so that, upon tightening, the nut compresses the outwardly flared portion of the tube in between the ferrule and the ball thus sealingly coupling the tube to the body in fluid communication with the passageway formed through the ball.
