* J 45004 Fuel Tank Drain Hose
* Commercially Available Fuel Pump
Fuel Tank Draining Method 1
1. Ignition OFF.
Warning: Refer to Battery Disconnect Warning (Service Precautions).
2. Disconnect the battery negative cable. Refer to Battery Negative Cable Disconnection and Connection (Battery Negative Cable Disconnection and Connection).
Danger: To avoid any vehicle damage, serious personal injury or death, always use the jackstands to support the vehicle when lifting the vehicle with a jack.
Warning: Refer to Safety Glasses Warning (Safety Glasses Warning).
3. Raise and support the vehicle. Refer to Lifting and Jacking the Vehicle (Service and Repair).
4. Remove the right rear wheel. Refer to Tire and Wheel Removal and Installation (Service and Repair).
Warning: Refer to Gasoline/Gasoline Vapors Warning (Service Precautions).
Warning
Never drain or store fuel in an open container. Always use an approved fuel storage container in order to reduce the chance of fire or explosion.
5. Remove the retaining hose clamp (1) from the fuel filler hose (2).
6. Remove the retaining hose clamp (3) from the fuel filler hose (2).
7. Remove the fuel filler hose (2) from the vehicle.
Note: Up to approximately 36 liters (8 gallons) of residual fuel may remain in the secondary side of the fuel tank.
Note: The fuel flapper door holder (2) J 42960-2 is used to keep the roll over anti spill valve open.
8. Install the fuel flapper door holder (2) J 42960-2 to the fuel tank fuel filler pipe (1).
9. Insert the fuel tank drain hose (3) J 45004 through the fuel flapper door holder (2) J 42960-2 until the fuel tank drain hose (3)J 45004 reaches the bottom of the tank.
10. Use a commercially available pump to drain the fuel from the fuel tank.
Adding The Drained Fuel to The Fuel Tank for Method 1
1. Remove the fuel tank drain hose (3) J 45004 from the fuel flapper door holder (2) J 42960-2 .
2. Remove the fuel flapper door holder (2) J 42960-2 from the fuel tank fuel filler pipe (1).
Warning
Never drain or store fuel in an open container. Always use an approved fuel storage container in order to reduce the chance of fire or explosion.
3. Install the fuel filler hose (2) to the vehicle.
Caution: Refer to Fastener Caution (Fastener Caution).
4. Install the retaining hose clamp (3) to the fuel filler hose (2) and tighten to 4 Nm (35 lb in).
5. Install the retaining hose clamp (1) to the fuel filler hose (2) and tighten to 4 Nm (35 lb in).
6. Install the right rear wheel. Refer to Tire and Wheel Removal and Installation (Service and Repair).
7. Lower the vehicle to the ground. Refer to Lifting and Jacking the Vehicle (Service and Repair).
8. Add the drained fuel to the fuel tank.
9. Connect the battery negative cable. Refer to Battery Negative Cable Disconnection and Connection (Battery Negative Cable Disconnection and Connection).
Fuel Tank Draining Method 2
1. Install the fuel pressure gauge to the vehicle. Refer to Fuel Pressure Gauge Installation and Removal (Fuel Pressure Gauge Installation and Removal).
2. Place the bleed hose of the fuel pressure gauge into a suitable container.
Note: Do not leave the vehicle unattended when performing this procedure.
3. Command the fuel pump ON with a scan tool.
Note: Do not fully open the bleed valve on the fuel pressure gauge. To drain both sides of the fuel tank simultaneously there should be a restriction on the flow rate at the bleed hose.
4. Open the bleed valve on the fuel pressure gauge just enough to cause a restriction to the flow of the fuel rate at the bleed hose.
Note: To avoid damage to the fuel pump do not allow the fuel pump to run dry while the fuel pump is in the ON state.
5. Command the fuel pump OFF with the scan tool as soon as it is observed that no more fuel is coming out of the bleed hose.
6. Remove the fuel pressure gauge from the vehicle. Refer to Fuel Pressure Gauge Installation and Removal (Fuel Pressure Gauge Installation and Removal).
Adding The Drained Fuel to The Fuel Tank for Method 2
1. Lower the vehicle to the ground. Refer to Lifting and Jacking the Vehicle (Service and Repair).
2. Add the drained fuel to the fuel tank.
