WARNING
Before fitting a new high-pressure pipe, lightly
lubricate the nut threads with the oil from the
applicator provided in the new parts kit.
Be careful not to allow oil into the high-pressure
pipe.
Do not lubricate high-pressure pipes supplied
without an applicator, as these high-pressure
pipes are self-lubricating.

REMOVAL
I - REMOVAL PREPARATION OPERATION
aPosition the vehicle on a two-post lift (see Vehicle:
Towing and lifting) (02A, Lifting equipment).
aDisconnect the battery (see Battery: Removal - Re-
fitting) (80A, Battery).
II - REMOVAL OPERATION
aUnclip:
-the fuel filter on the fuel vapour absorber in the di-
rection of the arrow (1) ,
-the fuel vapour absorber in the direction of the ar-
row (2) . IMPORTANT
During this oper ation, be sure to:
-refrain from smoking or bringing red hot objects
close to the working area,
-be careful of fuel splashes when disconnecting the
union.
IMPORTANT
Wear goggles with side protectors for this opera-
tion.
IMPORTANT
Wear leaktight gloves (Nitrile type) for this opera-
tion.
WARNING
To avoid any corrosion or damage, protect the
areas on which fuel is likely to run.
WARNING
Keep the pipe unions away from contaminated
areas.
WARNING
To prevent impurities from entering the circuit, place
protective plugs on all fuel circuit components
exposed to the open air.
