      *1 O-ring

      Apply a light coat of gasoline or spindle oil to new O-rings, and then install one onto each fuel injector assembly.

    2. Apply a light coat of gasoline or spindle oil where the fuel delivery pipe contacts each O-ring.

    3. B001O62

      While turning the fuel injector assembly left and right, install it to the fuel delivery pipe.

      Note


      • Do not damage the fuel injector assembly and O-ring.

      • Do not twist the O-ring.

      • After installing each fuel injector assembly, check that it turns smoothly. If not, replace the O-ring with a new one.

      Tech Tips

      Use the same procedure to install the other fuel injector assemblies.

  2. INSTALL FUEL DELIVERY PIPE

      *1 Fuel Delivery Spacer
      *2 Injector Vibration Insulator
      *a Fuel Delivery Pipe Side
      *b Cylinder Head Side

      Install 4 new injector vibration insulators to the cylinder head.

    2. Install the 2 fuel delivery spacers onto the cylinder head.

      Tech Tips

      Install the fuel delivery spacer so that the longer protrusion is on the cylinder head side.

    3. Install the fuel delivery pipe with the 4 fuel injector assemblies and install the 2 bolts.

      Torque:
      21 N*m  { 214 kgf*cm, 15 ft.*lbf }

      Note


      • Do not drop the fuel injector assemblies when installing the fuel delivery pipe.

      • Check that the fuel injector assemblies rotate smoothly after installing the fuel delivery pipe.

  3. CONNECT WIRE HARNESS


    1. B001NX3

      Engage the clamp to connect the wire harness.

    2. Install the 2 wire harness brackets to the intake manifold with the 2 bolts.

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

    3. Connect the 4 fuel injector assembly connectors, throttle body with motor assembly connector and sensor wire connector.

  4. INSTALL VACUUM SWITCHING VALVE ASSEMBLY (for ACIS)

      *a Retainer
      *b O-ring
      *c Fuel Tube Connector
      *d Fuel Pipe
      *e Nylon Tube

      Connect the fuel tube sub-assembly to the fuel pipe.

      Note

      Check if there is any damage or foreign matter on the connecting parts of the fuel lines.


      1. Align the fuel tube connector with the fuel pipe, and push them together until the fuel tube connector makes a "click" sound. If it is difficult to push the fuel pipe into the fuel tube connector, apply a small amount of clean engine oil to the tip of the fuel pipe and reinsert it.

      2. After connecting the fuel lines, check that the fuel pipe and fuel tube connector are securely connected by pulling on them.

    2. Engage the claw and install the No. 1 fuel pipe clamp.

    3. Engage the clamp to connect the fuel tube sub-assembly to the fuel hose clamp.
