 INSTALLATION
                                                                             Groove
 Apply the engine oil to a new O-ring.
 Install the fuel injector into the fuel pipe.
 Ensure the clip of the fuel injector inserted
 into the groove of the fuel pipe.




                                                                                      clip

 Install the fuel pipe into the intake manifold

 Be careful not to damage the O-ring.
 Tighten the fuel pipe mounting bolts.




 FUEL INJECTOR CLEANING
 PROBLEM
 1. Fuel Injector cannot output the fuel.                      O-ring
 2. The Injector injection time (ms) is shorter
    or longer.                                        Fuel
