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.Level the vehicle.

2.Complete the “BEFORE SERVICE PRECAUTION”. (See BEFORE SERVICE PRECAUTION [SKYACTIV-G (WITHOUT CYLINDER DEACTIVATION (US))].)

3.Drain the fuel. (See FUEL DRAINING PROCEDURE [SKYACTIV-G (WITHOUT CYLINDER DEACTIVATION (US))].)

4.Remove the fuel tank and fuel pump unit as a single unit. (See FUEL TANK REMOVAL/INSTALLATION [SKYACTIV-G (WITHOUT CYLINDER DEACTIVATION (US))])

5.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 (WITHOUT CYLINDER DEACTIVATION (US))].)

6.Remove the port C plug

7.Place the fuel tank in a level position.

8.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.

9.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 (WITHOUT CYLINDER DEACTIVATION (US))].)

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

11.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 (WITHOUT CYLINDER DEACTIVATION (US))].)

12.Turn the fuel tank upside down.

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

14.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 (WITHOUT CYLINDER DEACTIVATION (US))].)
