      *b Pump Drive Cam (Engine Oil Application Area)
      *c Pump Lifter (Engine Oil Application Area)
      *d Knock Pin
      *e Pin Hole

      Apply 30 cc (1.8 cu. in.) of engine oil to the pump drive cam.

    7. Apply engine oil to the fuel pump lifter assembly.

    8. Apply engine oil to 2 new O-rings and install them to the No. 4 camshaft bearing cap.

    9. Install a new fuel pump spacer gasket to the cylinder head cover sub-assembly.

    10. Set the fuel pump assembly on the cylinder head cover sub-assembly.

      Tech Tips

      Align the pin holes of the fuel pump lifter guide with the knock pins of the No. 4 camshaft bearing cap.

    11. Temporarily install the fuel pump assembly with the 2 bolts, leaving some allowance for left and right movement.

  2. TEMPORARILY INSTALL NO. 1 FUEL PIPE SUB-ASSEMBLY

    Note

    Do not damage the seals of the union nuts of the No. 1 fuel pipe sub-assembly when installing.


    1. Connect the No. 1 fuel pipe sub-assembly to the fuel pump assembly and tighten the union nut by hand.

    2. Connect the No. 1 fuel pipe sub-assembly to the fuel delivery pipe sub-assembly and tighten the union nut by hand.

  3. INSTALL FUEL PUMP ASSEMBLY

    1. Tighten the 2 bolts.

      Torque:
      30 N*m  { 306 kgf*cm, 22 ft.*lbf }

    2. Connect the fuel pump assembly connector.

  4. INSTALL NO. 1 FUEL PIPE SUB-ASSEMBLY


    1. B007Z26C01
      *a 17 mm Union Nut Wrench
      *b Torque Wrench Fulcrum Length

      Using a 17 mm union nut wrench, tighten the union nut on the fuel delivery pipe sub-assembly side of the No. 1 fuel pipe sub-assembly.

      Torque:
      Specified tightening torque
      35 N*m  { 357 kgf*cm, 26 ft.*lbf }

      Note

      Do not adjust the torque in the loosening direction.

      Tech Tips


      • Calculate the torque wrench reading when changing the fulcrum length of the torque wrench.

      • When using a 17 mm union nut wrench (fulcrum length of 30 mm (1.18 in.)) + torque wrench (fulcrum length of 180 mm (7.09 in.)): 30 N*m (306 kgf*cm, 22 ft.*lbf)

    2. Using a 17 mm union nut wrench, tighten the union nut on the fuel pump assembly side of the No. 1 fuel pipe sub-assembly.

      Torque:
      Specified tightening torque
      35 N*m  { 357 kgf*cm, 26 ft.*lbf }

      Note

      Do not adjust the torque in the loosening direction.
