  2. RELEASE THE INTERNAL PRESSURE 
    1. Disconnect the fuel pump connector (A).
    2. Start the engine and wait until fuel in fuel line is exhausted.
    3. After the engine stalls, turn the ignition switch to OFF position and disconnect the negative (-) terminal from the battery.
      NOTE: Be sure to reduce the fuel pressure before disconnecting the fuel feed hose, otherwise fuel will spill out.

  3. INSTALL THE SPECIAL SERVICE TOOL (SST) FOR MEASURING THE FUEL PRESSURE 
    1. Disconnect the fuel feed hose from the delivery pipe.
      CAUTION: Cover the hose connection with a shop towel to prevent splashing of fuel caused by residual pressure in the fuel line.
    2. Install the Fuel Pressure Gauge Adapter (09353-38000) between the delivery pipe and the fuel feed hose.
    3. Connect the Fuel Pressure Gauge Connector (09353-24000) to the Fuel Pressure Gauge Adapter (09353-38000)
    4. Connect the Fuel Pressure Gauge and Hose (09353-24100) to Fuel Pressure Gauge Connector (09353-24000).
    5. Connect the fuel feed hose to the Fuel Pressure Gauge Adapter (09353-38000).

  4. INSPECT FUEL LEAKAGE ON CONNECTION 
    1. Connect the battery negative (-) terminal.
    2. Apply battery voltage to the fuel pump terminal and activate the fuel pump. With fuel pressure applied, check that there is no fuel leakage from the fuel pressure gauge or connection part.

  7. REMOVE THE SPECIAL SERVICE TOOL (SST) AND CONNECT THE FUEL LINE 
    1. Disconnect the Fuel Pressure Gauge and Hose (09353-24100) from the Fuel Pressure Gauge Connector (09353-24000).
    2. Disconnect the Fuel Pressure Gauge Connector (09353-24000) from the Fuel Pressure Gauge Adapter (09353-38000).
    3. Disconnect the fuel feed hose from the Fuel Pressure Gauge Adapter (09353-38000).
    4. Disconnect the Fuel Pressure Gauge Adapter (09353-38000) from the delivery pipe.
      CAUTION: Cover the hose connection with a shop towel to prevent splashing of fuel caused by residual pressure in the fuel line.
    5. Connect the fuel feed hose to the delivery pipe.
  8. INSPECT FUEL LEAKAGE ON CONNECTION 
    1. Connect the battery negative (-) terminal.
    2. Apply battery voltage to the fuel pump terminal and activate the fuel pump. With fuel pressure applied, check that there is no fuel leakage from the fuel pressure gauge or connection part.
    3. If the vehicle is normal, connect the fuel pump connector.
