REMOVAL SERVICE POINT

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

INSTALLATION SERVICE POINT

>>A<< FUEL INJECTORS INSTALLATION

caution
  • The fuel injectors are classified into A, B and C by the injection quantity. When replacing one of fuel injectors, use a same identification mark fuel injector as the other fuel injectors.
  • When replacing the fuel injectors of all cylinders, use the same identification mark fuel injectors.

>>B<< FUEL INJECTOR ASSEMBLY/MPI DELIVERY PIPE PRESSURE REGULATOR/FUEL HIGH-PRESSURE HOSE INSTALLATION
caution Do not let the engine oil get into the delivery pipe will be damaged.
1.Apply a drop of new engine oil to the O-ring.
2.Turn the fuel injector assembly to the right and left to install to the fuel delivery pipe. Repeat for fuel high-pressure hose. Be careful not to damage the O-ring. After installing, check that the item turns smoothly.
3.If it dose not turn smoothly, the O-ring may be trapped, remove the item, re-install it into the fuel delivery pipe and check again.
4.Tighten the MPI delivery pipe pressure regulator and fuel high-pressure hose to the specified torque.
Tightening torque:

    8.9 ± 1.9 N·m <MPI delivery pipe pressure regulator>
    5.0 ± 1.0 N·m <Fuel high-pressure hose>
