Intake manifold ASSY (FA20): Reassembly

  1. INSTALL NO. 3 FUEL DELIVERY PIPE
    1. Install the No. 3 fuel delivery pipe to the intake manifold with the 3 clamps. (Transmission A/T)
    2. Install the No. 3 fuel delivery pipe to the intake manifold with the 2 clamps. (Transmission M/T)

  2. Fuel delivery pipe installation (bank 2 side)
    1. Apply gasoline to two new seal rings and install them to the fuel injector ASSY.
      CAUTION: Make sure there is no damage to or foreign matter in seal ring grooves of the injector.
    2. With the fuel injector ASSY installed on the fuel delivery pipe (bank 2 side), install it to the intake manifold.
      CAUTION:
      • Be careful not to twist the seal ring.
      • After it is attached to the fuel delivery pipe (bank 2 side), confirm that it can be rotated relatively lightly. If it cannot be rotated, remove the injector and repeat the work after replacing the seal rings with new ones.
    3. With 2 bolts, install the fuel delivery pipe (bank 2 side) to the intake manifold.

      Standard value: T=19N.m {194kgf.cm} {14ft.lbf}

    4. Align the axis of the fuel delivery pipe NO. 3 connector and the axis of the pipe, connect them, and push the retainer until you hear the click.
      CAUTION:
      • Before starting the work, check that there is no damage to or foreign material on the fuel delivery pipe NO. 3 connector and the pipe connection.
      • After connecting fuel delivery pipe NO. 3, check that the fuel delivery pipe NO. 3 connector and the pipe are securely attached.
  3. INSTALL FUEL DELIVERY PIPE (for Bank 1)
    NOTE: Use the same procedure described for the fuel delivery pipe (for bank 2).
  4. INSTALL CAP (for Automatic Transmission)
    1. Install the cap to the intake manifold.
