(1) Fuel tank
(2) Dipstick
(3) Electrical diesel fuel reheater
(4) Man ual priming pump
(5) Diesel filter
(6) High pressure pump
(7) Fuel fl ow actuator
(8) Injector rail
(9) Injector rail pressure sensor

IMPORTANT
Loosening a high pressure pipe union when the
engine is running is strictly prohibited.
WARNING
It is forbidden:
-to dismantle the interior of the pump or injectors.
-to remove the pressure sensor from the fuel rail
(because of circuit contamination problems). If the
pressure sensor fails, the pressure sensor, the rail
and the five high pressure pipes must be replaced,
-to dismantle the flow regulator solenoid valve and
the pressure regulator solenoid valve on the high
pressure pump.

REMOVAL
I - REMOVAL PREPARATION OPERATION
aPosition the vehicle on a two-post lift (see Vehicle:
Towing and lifting) (MR 411, 02A, Lifting equip-
ment).
aRemove the front engine cover.II - OPERATION FOR REMOVAL OF PART
CONCERNED
aDetach the fuel pipe from the body.
aDisconnect the electric diesel fuel heater fuel pipe
union (1) .
aUnclip the fuel pipe. IMPORTANT
During this operation, 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 latex gloves during the operation.
IMPORTANT
Consult the safety and cleanliness advice and
operation recommendations before carrying out
any repair (see 13B, Diesel injection, Diesel
injection: Precautions for the repair, page
13B-1) .
WARNING
To avoid any corrosion or damage, protect the
areas on which fuel is likely to run.
WARNING
Prepare for the flow of fluid, and protect the sur-
rounding components.

WARNING
To prevent impur ities from entering the circuit,
plugs must be fitted to the openings of all the fuel
circuit components exposed to the open air.
WARNING
Keep the pipe unions away from contaminated
areas.
