    Fuel hose connector removal procedure 

    If removal of the fuel hose connector is required for transmission servicing and/or replacement, follow the steps below.

    NOTE:
    • An O-ring is used as a seal between the fuel pipe and the connector. Take care not to damage the contact surfaces during the removal procedure. Do not allow the surface to become contaminated with dirt or other foreign material.

    • Perform the entire removal procedure with your hands. Do not use tools.

    Separating the connector and fuel pipe 

    1. Clean the fuel pipe and connector to remove mud and other dirt.
    2. For removal of the quick connector, hold the quick connector in one hand, and pull out the connector with the other hand while pressing the square relieve button of the connector, as illustrated.

    NOTE: Do not use tools of any kind. Only use bare hands when disconnecting the connector. Use a lubricant (light oil) and/or push and pull the connector until the pipe is disconnected.
    Cover the connectors that was removed with a plastic bag, to prevent dust or rain water from entering.

    Reuse of Quick-Connector 

    • Replace the port and connector if scratch, dent or crack is found.
    • Remove any dirt build up on the port when installing the connector. Replace the connector, if there is any forms of rust, dent, scratch.
    • After cleaning the port, insert it straight into the connector until it clicks. After it clicks, try pulling it out to make sure that it is not drawn and is securely locked.

    Assembling Advice 

    By applying engine oil or light oil to the pipe, port makes pipe assembly easier. The pipe assembly should take place immediately after applying oil (to prevent dust from sticking to the pipe surface - which may decrease sealing ability).

  6. Disconnect transmission harness and ECGI harness connector and clip.

    Connector: Output revolution sensor, input revolution sensor, transmission wire, neutral start switch (mode switch), H-L neutral switch (4x4), oil temperature sensor, 4WD switch (4x4), motor actuator (4x4) and car speed sensor.
