FUEL PUMP (for High Pressure): Installation

1. 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.

   HINT:

   By not using the camshaft pointed side to push up the pump activation 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. Apply a coat of engine oil to the pump activation cam and pump lifter part.

4. 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.

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

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

4. Install the No. 3 fuel pipe to the delivery pipe with the 2 bolts and tighten them in several passes.

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

5. Install the fuel pump with the 2 nuts and tighten them in several passes.

   Torque: 25 N*m (255 kgf*cm, 18 ft.*lbf) 

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

   Torque: without union nut wrench 

   30 N*m (306 kgf*cm, 22 ft.*lbf) 

   with union nut wrench 

   27 N*m (275 kgf*cm, 20 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.

   HINT:

   • Use a torque wrench with a fulcrum length of 30 cm (11.81 in.).
   • Make sure union nut wrench and torque wrench are connected in a straight line.
7. Connect the connector to the fuel pump.

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