REMARK:
Only vehicle observing the de-pollution norm EURO 00 are equipped with shock
sensor.

PURPOSE
To avoid the fire hazard due to the fuel losses, that may occur in case of an accident.
OPERATION
The hazard sensor (1) is placed in the engine compartment, being mounted on the left shock
absorber column.
In case of shock, the sensor ball leaves its lodgement, thus interrupting the electric circuit
between the control relay of the petrol electric fuel pump and the electric petrol pump.
HAZARD SENSOR RE-STARTING
The upper part of the hazard sensor is to be pushed to re-position the ball into its lodgement
and thus to re-start the sensor.

Fuel ramp
ATTENTION !
When opening the fuel circuit, protect
by means of a gauze piece against petrol
splashing due to residual pressure.
DISMOUNTING
Disconnect the battery.
Dismount the air filter.
Disconnect:
- pipe 1 for fuel supply;
- pipe 3 for fuel return;
- pipe 4 of the pressure controller.
REMARK:
For EURO 00 and EURO 96, the
pressure controller and return pipe are
placed in the fuel tank.
Dismount the attachment screws (2) of the
fuel ramp.
Dismount the ramp.
In order to dismount an injector, retrieve
the clip 5, and then extract the injector.
REMOUNTING
Replace the annular gaskets from the
injectors bottom; if the injector has been
dismounted, the gasket from the injector’s
head will be also replaced.
In order that petrol fuel supply and return
connection are correctly mounted, a ”clic”
must be heard when connecting.
Perform the dismounting operations in the
reverse order.

PUMP CAPACITY CHECKING
SPECIAL TOOLS
Pliers for “CLICK” collars.
IMPORTANT
During this operation, it is obligatory :
- not- smoking and not bringing
incandescent objects at the working place;
- protect against petrol splashing due
to residual pressure remained in piping
during their dismounting.
VEHICLES WITH FUEL RETURN
The checking of the fuel pump capacity is
recommended to be performed by the fuel
return hose connected on the level transmitter-
pump assembly.
Disconnect the fuel return pipe (1).
Connect on the pipe a hose, one extremity
being introduced in a calibrated vessel, from 0
to 2000 ml.
VEHIC LES WITHOUT FUEL
RETURN
Disconnect the supply pipe from the fuel
electric pump assembly.
Connect on the pipe a hose, one extremity
being introduced in a calibrated vessel from 0
to 2000 ml.
Start the fuel electric pump by bridging the
3 and 5 terminals of the fuel pump H relay
(placed in the fuse and relays box from engine
compartment).
The pump output must be minimum 1.3 l /
min at 12 V.
If the output is not correct, check the pump
supply voltage (capacity is decreasing by
approximate 10% for a voltage drop of 1 V).

ATTENTION !
When opening the fuel circuit, protect
by means of a gauze piece against petrol
splashing due to residual pressure from
the supply circuit.
Dismount the air filter.
Disconnect the fuel supply hose.
Connect the MOT 1311-04 device on the
ramp, and then reconnect the fuel supply
piping to the connection.
Mount the manometer 0 ÷ 10 bar and
the flexible hose MOT 1311 – 01.
Bridge the terminals 3 and 5 of the fuel pump
relay H, placed in the fuse and relays box.
The measured pressure must be 3.5 bars.
For vehicles with fuel circuit without return
(controller mounted on pump), the pressure is
constant.
