FUEL TANK INSPECTION [SKYACTIV-G 2.0]

id0114z5803200

Warning

•  Fuel vapor is hazardous. It can very easily ignite, causing serious injury and damage. Always keep sparks and flames away from fuel.

•  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 performing work on the fuel system, discharge static electricity by touching the vehicle body.

Note

•  The rollover valve and also fuel tank leakage are inspected in this inspection.

1.  Remove the fuel tank and fuel pump unit as a single unit. (See FUEL TANK REMOVAL/INSTALLATION [SKYACTIV-G 2.0])

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

(1)  Plug the fuel pump unit pipe, and ports B and C.

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

(3)  Verify that there is no change in the pressure and no air leakage from the fuel tank.

•  If there is air leakage, replace the fuel tank. (See FUEL TANK REMOVAL/INSTALLATION [SKYACTIV-G 2.0].)

•  If there is no malfunction, go to the next step.

3.  Remove the port C plug

4.  Place the fuel tank in a level position.

5.  Close port A and apply 5.9 kPa {44 mmHg, 1.7 inHg} of pressure to port C, and leave it in this condition momentarily.

6.  Open port A and verify that the pressure decreases from 5.9 kPa {44 mmHg, 1.7 inHg}.

•  If it cannot be verified, replace the fuel tank. (See FUEL TANK REMOVAL/INSTALLATION [SKYACTIV-G 2.0].)

•  If there is no malfunction, go to the next step.

7.  Close port A and apply -2.0 kPa {-15 mmHg, -0.59 inHg} vacuum to port C, and leave it in this condition momentarily.

8.  Open port A and verify that the -2.0 kPa {-15 mmHg, -0.59 inHg} negative pressure condition restores to near positive pressure.

•  If it cannot be verified, replace the fuel tank. (See FUEL TANK REMOVAL/INSTALLATION [SKYACTIV-G 2.0].)

•  If there is no malfunction, go to the next step.

9.  Turn the fuel tank upside down.

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

11.  Verify that there is no change in the pressure and no air leakage from the port C.

•  If there is air leakage, replace the fuel tank. (See FUEL TANK REMOVAL/INSTALLATION [SKYACTIV-G 2.0].)

•  If there is no malfunction, the fuel tank is normal therefore the inspection is completed.
