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.

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.
