ence occurs, replace O-ring.
3. Insert fuel injector into fuel tube with clip attached.
●Insert it while matching it to the axial center.
●Insert fuel injector so that projection B of fuel injector matches
notch B of the clip.
●Make sure that fuel tube flange is securely fixed in flange fixing groove on clip.
●Make sure that installation is complete by checking that fuel injector does not rotate or come off.
