FUEL PUMP (for High Pressure): Installation

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

   HINT:

   When installing the fuel pump by following the procedure described above: By not using the crankshaft pointed side to push up the pump activation surface, it is easier to install the fuel pump and No. 2 fuel pipe later.

2. Pour 30 cc of engine oil through the cylinder head cover's fuel pump attachment hole into the cylinder head oil collector.

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.
5. Temporarily install the No.2 fuel pipe sub-assembly to the fuel pump assembly.

   NOTE: Be careful not to damage the sealing surface of the fuel pipe when temporarily installing the fuel pipe.
6. Install the 2 nuts and tighten them in several passes.

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

7. Connect the fuel hose.

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

2. Using a 19 mm union nut wrench, connect the fuel pipe.

   Torque: 30 N*m (306 kgf*cm, 22 ft.*lbf) 

   HINT:

   The torque shown above should be used for tightening without using union nut wrench. When the union nut wrench is used for tightening, the torque should be calculated based on the length of the union nut wrench (See REPAIR INSTRUCTION ).

3. Connect the connector to the fuel pump.

HINT:

Installation procedure of the RH side is the same as that of the LH side.

1. Perform initialization (See INITIALIZATION ).

   HINT:

   Certain systems need to be initialized after reconnecting the cable to the negative (-) battery terminal.
