      CAUTION: Be careful to a direction of the tool.
      NOTE: For correcting any elongation of the seal ring that occurs when the injector seal drift is installed, use the Tool so that the seal ring is pressed and contracted.
  3. Install O-ring and backup ring to fuel injector. When handing new O-ring and backup ring, paying attention to the following caution items:
    CAUTION:
    • Do not reuse O-ring and backup ring.
    • Handle O-ring with bare hands. Do not wear gloves.
    • Lubricate O-ring with new non-silicone engine oil.
    • Do not allow engine oil to enter fuel passage ways.
    • Do not clean O-ring with solvent.
    • Check that O-ring and its mating part are free of foreign material.
    • When installing O-ring, be careful not to scratch it with tool or fingernails. Also be careful not to twist or stretch O-ring. If O-ring was stretched while it was being attached, do not insert it quickly into fuel tube.
    • Insert new O-ring straight into fuel rail. Do not de-center or twist it.
    • Always install the back up ring (1) in the right direction as instructed.

    1. Install fuel injector holder (5) to fuel injector.
      CAUTION:
      • Do not reuse injector holder. Replace it with a new one.
      • Be careful to keep fuel injector holder from interfering with O-ring. If interference occurs, replace O-ring.
    2. Insert fuel injector into fuel rail with fuel injector holder attached.
      • Insert it while matching it to the axial center.
      • Insert so that protrusion (A) of fuel injector is aligned to cutout (B).
    3. Check that installation is complete by checking that fuel injector does not rotate or come off.
      • Check that protrusions of fuel injectors and fuel rail are aligned with cutouts of clips after installation.
  5. Insert insulator into fuel injector bore in cylinder head.
  6. Install fuel rail and fuel injector assembly to cylinder head.
    • Tighten bolts and nuts in two steps in numerical order as shown in the figure.
