SERVICE:1. Removing the protective plate
Remove the protective plate on the left-hand side of the fuel tank.
2. NOTE!
On some models there is a rear protective plate on the fuel tank, if so, remove the bolt in the top right-hand corner as well and fold out the protective plate slightly.
3. Inspecting the mounting
Important!
The fuel tank must be dry from all moisture caused by rain or snow prior to inspecting.
Check the area around the mountings for leaking fuel or cracks. (See picture in step 4)
If the car is equipped with a rear protective plate then check this mounting too.
NOTE!
If fuel tank has cracks or leakage around the attaching lugs then the tank must be replaced. Refer to page 5 shown.
After replacing the tank or if it is considered OK then the protective plate(s) must be refitted with rubber dampers see step 5.
4. Inspecting the mounting
Check the area around the mountings for leaking fuel and/or cracks.
5. Installing the rubber dampers
Install the rubber dampers to the lugs on the tank with the hexagon part of the damper facing the tank.
Tighten the rubber damper so that the hexagon just contacts with the lug surface, then angle tighten an additional 45° (1/8 of a turn).
6. Adjusting the protective plate
Cut off the shaded area as marked in the illustration.
A = 173 mm
B = 135 mm
7. Installing the protective plate
Install the protective plate, tighten the nuts to 10 Nm.
8. Installing the rubber damper to the rear protective plate
NOTE!
Only applies to cars with a rear protective plate for the tank.
Install the rubber damper in the same way as in the previous steps.

Caution!
Lift unit straight up. Do not grip pipe connections with pliers or other sharp tool as damage to connections may result in fuel leakage.
18. Installing fuel tank
NOTE!
This step is only information. Follow the method from step 19.
When installing a new fuel tank the following components must be replaced with new parts because the material swells. Failure to do so may result in fuel leakage.
- Level sensor nut (white) (9142607)
- Level sensor nut seal (447142)
- Fuel pump (FP) nut (black) (3501322)
