DISMOUNTIN G
Place the vehicle on a two-columns
elevator. Disconnect the battery.
Dismo unt :
- the air filter assembly;
- the acceleration cable from the body
control lever; - the injection ramp ( see c hapter 13
“Injection ramp”).
Disconnect the electric connectors:
- body position potentiometer ( 1)
- atmospheric pressure sensor (2)
- step-by-step engine (3);
- air temperature sensor( 4)
Disconnect the fuel supply ducts (supply and return)
Disconnect the petrol vapors re-aspiration hose from the inlet manifold.
Uncouple the body control lever and remove the valve body.
Dismount the attachment nuts and screws of the inlet manifold.
Extract the inlet manifold .
REMOU NT I NG
Replace the inlet manifold gaskets.
Tighten at the required moment the inlet manifold nuts and screws, observing the sequence
shown in the drawing.
Perform the dismounting operations in the reverse order.

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 l eaves its lodgement, t hus interrupting the electric c ircuit
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 i nto its lodgement
and thus to re-start the sensor.

When opening the fuel circuit, protect
by means of a gauze piece against petrol

DISMOUNTIN G
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
pre ssure c ontrol ler and return pi pe are
placed in t he fuel tank.
Dismount the attachment screws ( 2) o f the
fuel ramp. Dismount the ramp. In order to dismount an injector, re trieve
the clip 5, and then extract the injector.
R EMOU NT I NG
Replace the annular gaskets from the
injectors bottom; if t he injector has been
dismounted, the gasket from the injector’s
head will be also replaced.
In order that petrol fuel supply and return
connection a re c orrectly m ounted, a ” clic”
must be heard when connecting. Perform the dismountin g operations in the
reverse order.

IMPORTANT
Duri ng this operation, it is obligatory :
- not - sm oki ng a nd not bri ngi ng
incandescent obj ects at the working pl ace; - 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 t he fue l
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. VE HIC
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
s upply voltage (capacity i s decreasing by
approximate 10% for a voltage drop of 1 V).

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

The measured pressure must be 3.5 bars.
Fo r vehicles with fuel circuit without return
(controller mounted on pump), the pressure is
constant.
