   1. Install a new O-ring, a new No. 1 fuel injector back-up ring, a new No. 2 fuel injector back-up ring and a new No. 3 fuel injector back-up ring to the fuel pipe plug sub-assembly as shown in the illustration.
      NOTE:

      • Check that there is no foreign matter or damage on the O-ring groove of the fuel pipe plug sub-assembly.
      • Check that the No. 1 fuel injector back-up ring and No. 3 fuel injector back-up ring are installed in the correct orientation.
      • Make sure that the No. 1 fuel injector back-up ring, No. 2 fuel injector back-up ring, No. 3 fuel injector back-up ring and O-ring are installed in the correct order.
      • Check that the opening of the No. 1 fuel injector back-up ring is not overlapped or stretched as shown in the illustration.
      • After installing the O-ring, check that it is not contaminated with foreign matter and is not damaged.
   2. Install a new gasket to the fuel pipe plug sub-assembly as shown in the illustration.
   3. Secure the fuel delivery pipe with sensor assembly LH (fuel pressure sensor) in a vise between aluminum plates.
      NOTE:

      Do not overtighten the vise.

   4. Using a 5 mm hexagon socket wrench, install the fuel pipe plug sub-assembly to the fuel delivery pipe with sensor assembly LH (fuel pressure sensor) with the 2 bolts.

      Torque: 10 N.m (102 kgf/cm, 7 ft.lbf) 

   5. Remove the fuel delivery pipe with sensor assembly LH (fuel pressure sensor) from the vise.

NOTE: Do not remove the fuel pressure sensor from the fuel delivery pipe with sensor assembly LH. If the fuel pressure sensor is removed, replace the fuel delivery pipe with sensor assembly LH (fuel pressure sensor) with a new one.

Refer to INSTALLATION [12/2023 - ] 

1. Perform "Inspection After Repair" after replacing the fuel delivery pipe with sensor assembly LH (fuel pressure sensor).
