      *5 Retainer
      A011T1X Pinch
      A011V7Q Pull

      Note

      • Check for foreign matter on the fuel tube around the fuel tube connector. Clean it if necessary. Foreign matter can affect the ability of the O-ring to seal the fuel tube connector and fuel pipe.

      • Do not use any tools to separate the fuel tube connector and fuel pipe.

      • Do not forcefully bend, kink or twist the nylon tube.

      • Keep the fuel tube connector and fuel pipe free from foreign matter.

      • If the fuel tube connector and fuel pipe are stuck, push and pull to release them.

      • Put the fuel tube connector and fuel pipe in plastic bags to prevent damage and contamination.

    3. Remove the fuel tube sub-assembly from the fuel hose clamp.

  11. REMOVE FUEL DELIVERY PIPE SUB-ASSEMBLY

    1. Remove the 2 bolts, and then remove the fuel delivery pipe together with the 4 fuel injectors.

      A011RLU

    2. Disconnect the fuel vapor feed hose.

      A011V5I

    3. Disconnect the 3 wire harness clamps and connector.

    4. Remove the bolt and wire harness clamp bracket.

    5. Apply battery voltage to the terminals of the connector to close the tumble control valves.

      A011TCJ
      Standard
      Tester Connection Specified Condition
      Positive (+) battery voltage applied to terminal 8 (M-), and negative (-) battery voltage applied to terminal 4 (M+) Open → Closed

      Note

      • If this procedure is not performed, the tumble control valves may be damaged when the intake manifold is removed.

      • Apply battery voltage for 1 to 3 seconds.

      • If battery voltage is applied for more than 3 seconds, the actuator may be damaged.

      • Do not allow the lead wires to contact the other terminals.

    6. Remove the bolt and separate the wire harness.
