Reprime the circuit using a fuel cock (R) placed on the
diesel filter (depending on version).
NOTE: certain vehicles are not fitted with a fuel cock.
In this case, ignore the repriming procedure.

After any intervention, check that there are no
leaks in the diesel circuit. Start the engine at idling
speed until the fan starts up, then accelerate several
times under no load.

IT IS FORBIDDEN TO REMOVE THE INTERIOR OF
AN INJECTOR OR TO SEPARATE THE INJECTOR
HOLDER FROM THE PIPE.
IMPORTANT: before any intervention, connect the
after-sales diagnostic tool, query the injection
computer and check that the injection rail is not under
pressure. Take note of the fuel temperature.SPECIAL TOOLING REQUIRED

Fit the high pressure pipe.
Loosen the high pressure pump/rail pipe.
Tighten to torque:
– the injector,
– the injector side connections, then the injection rail connections,
– the rail.
– the pump/rail pipe (high pressure pump side under pressure).
NOTE: it is essential that you replace the fuel return pipe placed on the
injectors during removal.

Checking diesel pressure and flow
It is possible to check the pressure and flow in the low pressure fuel circuit.
The low pressure is delivered by the supercharging pump (electric pump located under the diesel filter designed to
feed the high pressure pump).
SPECIAL TOOLING REQUIRED
Mot. 1311-01
Pressure gauge or
Mot. 1328
Mot. 1311-08 Pressure measuring connector
ESSENTIAL SPECIAL TOOLING
Graduated 2000 ml test tube
CHECK LOW PRESSURE
(SUPERCHARGING PUMP)
Place a "T" connector Mot. 1311-08, to position the
pressure gauge Mot. 1311-01 or Mot. 1328 at the
outlet (S) of the fuel filter or at the HP pump inlet.
Turn the fuel pump using the diagnostic tool or by
directly feeding the pump (each time the ignition is
switched on the low pressure pump is supplied for
30 seconds).
Measure the pressure which should be between
2.5 and 4 bars.CHECK THE FLOW (SUPERCHARGING PUMP)
Make the pump flow into a 2000 ml graduated test
tube. Turn on the ignition to run the pump. The pump is
supplied for 30 seconds if the engine is not started.
The flow read should be 80 to 100 litres/hour
minimum.
IMPORTANT: it is forbidden to measure the
pressure and the flow of the high pressure pump.

Pressure sensor
TIGHTENING TORQUES (In daN.m or/and°)
Pressure sensor 3.5 ± 0.5
IMPORTANT: before any intervention, connect
the after-sales diagnostic tool, query the injection
computer and check that the injection rail is not
under pressure. Take note of the fuel temperature.
PRESSURE SENSOR (1)
REMOVAL
Disconnect the battery.
Remove the sensor connector.
Unscrew the pressure sensor.REFITTING
Replace the seal.
Screw in the sensor then tighten it to torque.
Connect the connector. YOU SHOULD FOLLOW THE CLEANNESS
INSTRUCTIONS CLOSELY.
After any intervention, check that there are no leaks in the diesel circuit.
Start the engine at idling speed until the fan starts up, then accelerate
several times under no load.

TIGHTENING TORQUES (In daN.m or/and °)
Regulator bolt 0.9 ± 0.1
IMPORTANT: before any intervention, connect
the after-sales diagnostic tool, query the injection
computer and check that the injection rail is not
under pressure. Take note of the fuel temperature.
PRESSURE REGULATOR (2)
REMOVAL
Disconnect the battery.
Remove the regulator connector.
Remove the retaining bracket for the diesel
temperature sensor.
Unscrew the regulator mounting bolts.
Remove the regulator by turning in an anticlockwise
direction (do not use any tools as a lever when
removing the pump regulator).REFITTING
Change the seals.
Dampen the seals with clean diesel.
Replace the regulator in the pump by turning it in an
anticlockwise direction (do not use any tools as a lever
when replacing the pump regulator).
Fit the mounting bolts then tighten to torque.
Connect the connector. YOU SHOULD FOLLOW THE CLEANNESS
INSTRUCTIONS CLOSELY.
After any intervention, check that there are no leaks in the diesel circuit.
Start the engine at idling speed until the fan starts up, then accelerate
several times under no load.
