Fuel Tank: Testing and Inspection

NOTE: This inspection is for the 2 rollover valves integrated in the fuel tank. The evaporative gas check valve (two-way) is integrated with each rollover valve.

1. Remove the fuel tank.
2. Connect the SST to an air compressor.
3. Plug the fuel main pipe and fuel return pipe of the fuel pump unit.
4. Connect the SST to port B and plug port A.
5. Level the fuel tank.




6. Apply pressure of +5.9 kPa {+44 mmHg, +1.7 inHg} to port B and verify that there is airflow from port C.
- If there is no airflow, replace the fuel tank.
- If there is airflow, connect the SST to port C with port A plugged.




7. Apply pressure at +2.0 kPa {+15 mmHg, +0.59 inHg} to port C and verify that there is airflow from port B.
- If there is no airflow, replace the fuel tank.
- If there is airflow, connect the SST to port B and turn the fuel tank upside-down.




8. Apply pressure of +0.99 kPa {+7.4 mmHg, 0.29 inHg} to port B and verify that there is no airflow from port C.
- If there is airflow, replace the fuel tank.
