10.One end of the intake housing (7) has a rounded ball cavity (S) on the inside (see Fig. 9). Install the ball (13*) in this cavity, then screw the intake valve (5) into the intake housing handtight. See Fig. 10. The threads will engage easily until the seal contacts the sealing surface of the intake housing.

Orient so the end with the ball cavity (S, see Fig. 9)
