id0114c3803200

Note

•  The rollover valve built into the fuel tank, and check valves (two-way) built into the rollover valves are inspected in this inspection.

1.  Remove the fuel tank. (See FUEL TANK REMOVAL/INSTALLATION [MZ-CD 1.6 (Y6)].)

2.  Perform the following procedure to verify the fuel tank airtightness.

(1)  Plug the fuel gauge sender unit, ports B and C.

(2)  Apply a pressure of 5.9 kPa {44 mmHg, 1.7 inHg} to port A and wait for a while.

(3)  Verify that there is no air leakage from the fuel tank.

3.  Plug the fuel gauge sender unit and port B.

4.  Level the fuel tank.

5.  Apply a pressure of 5.9 kPa {44 mmHg, 1.7 inHg} to port A and wait for a while.

6.  With the pressure still applied, verify that there is airflow from port C and the pressure is 0—5.9 kPa {0—44 mmHg, 0—1.7 inHg}.

•  If there is no airflow, replace the fuel tank. (See FUEL TANK REMOVAL/INSTALLATION [MZ-CD 1.6 (Y6)].)

7.  Apply a pressure of –2.0 kPa {–15 mmHg, –0.59 inHg} to port A and wait for a while.

8.  With the pressure still applied, verify that there is airflow from port C and the pressure is 0—–2.0 kPa {0—–15 mmHg, 0—–0.59 inHg}.

•  If there is no airflow, replace the fuel tank. (See FUEL TANK REMOVAL/INSTALLATION [MZ-CD 1.6 (Y6)].)

•  If there is airflow, place the fuel tank upside down.

9.  Apply a pressure of 5.9 kPa {44 mmHg, 1.7 inHg} to port A and wait for a while.

10.  With the pressure still applied, verify that there is no airflow from port C.

•  If there is airflow, replace the fuel tank. (See FUEL TANK REMOVAL/INSTALLATION [MZ-CD 1.6 (Y6)].)
