Warning
-
• Highly pressurized fuel may spray out if the fuel line is cut. Due to the following dangers occurring with a fuel spray, always complete the “Fuel Line Safety Procedure” to prevent the fuel from spraying.
-
― Fuel may cause irritation if it comes in contact with skin and eyes.
― If fuel ignites and causes a fire, it may lead to serious injury or death, and damage to property and facilities.
• A person charged with static electricity could cause a fire or explosion, resulting in death or serious injury. Before draining fuel, make sure to discharge static electricity by touching the vehicle body.

Note
-
• The rollover valve and also fuel tank leakage are inspected in this inspection.
1. Perform the following procedure to verify the fuel tank airtightness.
- (1) Plug the fuel pump unit pipe, ports B and C.
-
- (2) Apply a pressure of 3 kPa {23 mmHg, 0.9 inHg} to port A and wait for a while.
-
- (3) Verify that there is no air flow leakage from the fuel tank.

-
2. Plug the fuel pump unit pipe and port B.
3. Level the fuel tank.
4. Apply a pressure of 3 kPa {23 mmHg, 0.9 inHg} to port A and wait for a while.
5. With the pressure still applied, verify that there is air flow from port C and the pressure is 0—3 kPa {0—23 mmHg, 0—0.9 inHg}.
-
6. Apply a pressure of -0.5 kPa {-3.8 mmHg, -0.1 inHg} to port A and wait for a while.
7. With the pressure still applied, verify that there is air flow from port C and the pressure is -0.5—0 kPa {-3.8—0 mmHg, -0.1—0 inHg}.
-
• If there is air flow, place the fuel tank upside down.
8. Apply a pressure to port A and wait for a while.
9. With the pressure still applied, verify that there is no air flow from port C.
