FUEL PUMP(for High Pressure) INSTALLATION

PROCEDURE


  1. INSTALL FUEL PUMP ASSEMBLY (for Bank 1)


    1. A001A4BE05

      Turn the camshaft until the flat of the cam is facing the cylinder head cover's fuel pump attachment hole, as shown in the illustration.

      Tech Tips

      By not using the camshaft lobe to push up the pump lifter surface, it is easier to install the fuel pump and No. 3 fuel pipe later.

    2. Pour 30 cm3(1.8 cu. in.) of engine oil through the cylinder head cover's fuel pump attachment hole into the cylinder head oil collector.

    3. A001C9CE07
      *1 Camshaft
      *2 Pump Lifter

      Apply a coat of engine oil to the pump activation cam and pump lifter.

    4. A001CJME07
      *1 Metal Eyelets

      Install a new fuel pump insulator to the cylinder head cover. Then pass the 2 stud bolts through the holes of the fuel pump and set them on the insulator.

      Note

      Install the insulator so that the open sides of the metal eyelets are facing outward, as shown in the illustration.

    5. A001953

      Temporarily install the fuel pump with the 2 nuts.

    6. A001BV1

      Connect the fuel hose.

  2. INSTALL NO. 3 FUEL PIPE SUB-ASSEMBLY


    1. Install a new O-ring, new backup rings (No. 1 and No. 2) and new E-ring to the fuel injector as shown in the illustration.

      A001AFRE07

      Note


      • Check that there is no foreign matter or damaged areas in the injector's O-ring groove.

      • Check that the No. 1 and No. 2 backup rings are installed in the correct direction.

      • Make sure that the backup rings and O-ring are installed in the correct order.

      • Check that the alignment openings of the backup rings are 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. A001DQP

      Apply engine oil to the O-ring.

      Note

      Make sure there is no gasoline on the O-ring and inside the installation hole.

    3. Temporarily install the No. 3 fuel pipe to the delivery pipe with the 2 bolts.

    4. A001COC

      Temporarily install the No. 3 fuel pipe sub-assembly to the fuel pump.

      Note

      Be careful not to damage the sealing surface of the fuel pipe when temporarily installing the fuel pipe.

    5. Tighten the 2 bolts in several passes.

      Torque:
      10 N*m  { 102 kgf*cm, 7 ft.*lbf }

    6. Tighten the 2 nuts in several passes.

      Torque:
      25 N*m  { 255 kgf*cm, 18 ft.*lbf }

    7. Using a 19 mm union nut wrench, tighten the union nut.

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

      Note


      • There must be absolutely no free play in the union on the fuel pump side. If the union on the fuel pump side has free play, replace the fuel pump.

      • Use the formula to calculate special torque values for situations where a union nut wrench is combined with a torque wrench Click here.

    8. Connect the fuel pump connector.

  3. INSTALL COVER SUB-ASSEMBLY (for Bank 1)

    A001F4EE03
    *1 Cover Sub-assembly RH
    *2 Cover Sub-assembly LH

    1. Attach the 5 claws and install the engine cover LH and RH to the fuel pump.

  4. INSTALL FUEL PUMP ASSEMBLY (for Bank 2)

    Tech Tips

    The installation procedures are the same as the bank 1 side.

  5. INSTALL NO. 2 FUEL PIPE SUB-ASSEMBLY

    Tech Tips

    The installation procedures are the same as the No. 3 fuel pipe sub-assembly.

  6. INSTALL COVER SUB-ASSEMBLY (for Bank 2)

    Tech Tips

    The installation procedures are the same as the bank 1 side.
