The following exploded drawing shows the attachment of the fuel filler neck and carbon canister in the right wheel housing.

No. 1 - 7:

WARNING:
Danger of fire.
- Keep clear of ignition sources.
- Do not smoke.
- Danger of fire due to naked flames and sparks, e.g. during welding or grinding work.
- Danger of fire due to escaping fuel, e.g. on hot engine components or due to electrostatic charge.
- Secure the vehicle, e.g. with a warning sign.
- Change any clothing soaked with fuel immediately.
- In case of fire, use CO(2) or dry powder fire extinguishers.

CAUTION:
- Please observe general warning notes and working regulations.
- For safety reasons, the tank should only be removed and installed when empty.

1. Replace the ground cable tie-wraps on the carbon canister and preassemble the ground cable. Lift the carbon canister into the wheel well.
2. Join all lines on the carbon canister and degassing tank at the plug connections.
3. Carefully attach the two electric plugs-3-on the carbon canister and on the leak diagnosis pump and the hose on the filler neck-2-of the leak diagnosis pump (USA). Then, connect plastic line -1-.







4. Insert the hose on the degassing tank.







CAUTION:
Risk of damage
- There is a risk of leaks if the overflow line on the filler neck is above the valve.
- Make sure that the line runs below the valve.

5. Swivel carbon canister down into installation position from behind. Make sure that the fuel overflow line -1- is below the solenoid valve-2-. If the line is not routed correctly, this will cause damage during subsequent operation.

Figure shows the correct position of the line. View from above without rear side section.







6. Tighten the five fastening screws on the carbon canister and the two on the degassing tank in the right wheel housing to 10 Nm (7.5 ftlb.) -arrows-.







7. Install rear right wheel housing liner.







8. Fit rear wheel and tighten to 160 Nm (118 ftlb.).
