REMOVAL SERVICE POINTS

<<A>> FUEL HIGH-PRESSURE HOSE DISCONNECTION

1.
caution Do not kink the fuel high-pressure hose as it is made of plastics.
Insert a flat-tipped screwdriver (6 mm wide and 1 mm thick) into the retainer of the fuel high-pressure hose connector.

2.
caution When pushing up the retainer of the fuel high-pressure hose connector, pay attention to avoid damage to the retainer.
Turn the flat-tipped screwdriver inserted into the retainer by 90 degrees to push up the retainer and unlock the fuel high-pressure hose connector.

<<B>> FUEL DELIVERY PIPE AND FUEL INJECTOR ASSEMBLY REMOVAL
caution Do not drop the fuel injector.
Remove the fuel delivery pipe with the fuel injectors attached to it.

3.Tighten the mounting bolts of the fuel delivery pipe to the specified torque.
Tightening torque: 12 ± 1 N·m

>>C<< FUEL HIGH-PRESSURE HOSE CONNECTION

1.Pull up the retainer of fuel high-pressure hose to unlock before installing.

2.
caution
  • When pushing in the retainer of the fuel high-pressure hose connector, pay attention to avoid damage to the retainer.
  • After the installation of the fuel high-pressure hose, slightly pull the fuel high-pressure hose to check that it is connected securely. At this time, also check that there is approximately 1 mm play.
Install the fuel high-pressure hose to the fuel delivery pipe securely and push in the retainer of the fuel high-pressure hose connector to lock the fuel high-pressure hose and fuel delivery pipe.
