AUTION

!

When the fuel circuit is opened, any
petrol jet due to residue pressure must
be averted by means of a gauze.

D

ISMO UNTING

The battery is disconnected.
The air-filter is taken out.
To disconnect:

-no. 1 fuel supply tube;
-no. 3 return fuel tube;
-no. 4 pressure-regulator tube.

Injection ramp Screws no. 2 are taken off.
The ramp is taken apart.

In order to take apart an injector,

withdraw clamp no. 5 and then pull the
injector.

MO UNTING

Replace the torric fittings at the base of

the injectors (if the injector has been taken
apart as well as the fitting at the end of the
injector).

For the supply junctions and the return

petrol tubes to be correctly coupled a click
must be heard the moment the coupling is
done.

The rest of the operations are done in

the reverse order as that of the taking apart.

EPLACEMENT

The replacement of the petrol filter is recommended for any overhauling or for max.

20,000 kilometers.

AUTION

!

When the fuel circuit is opened, any petrol jet due to residue pressure

must be averted by means of a gauze.

D

ISMO UNTING

Before every taking-apart operation, prevent fuel from leaking.
Clamps no. 1 are pushed and the speedy junctions are disconnected.
Screw no. 3 is taken off and the petrol filter is taken apart.

O UNTING

Observe the flowing direction of the fuel (which is shown by an arrow inscribed on

the filter).

Connect the speedy junctions back, by hand-pushing.
A correct coupling of the speedy junctions is ensured when there is a click at the

moment of the coupling.

It is recommendable to do the inspection

of the fuel pump-flow through the return fuel
hose which is connected on the pump-level
transmitter set.

MPO RTANT

!

During these operations it is compul-

sory:

-not to smoke or handle incandes-

cent objects at the working place;

-to ensure protection from  the petrol

projections due to residue pressure left in
the channeling during the taking-apart.

INSPECTION

The return channeling no. 1 of the fuel

supply is disconnected.

A  hose is connected on the junction

whose end is introduced in a graded vessel
(from 0 to 2000 ml)

Terminals 3 and 5 of H relay (lying in

the fuse-box of the motor-compartment) of
the petrol pump are shunted.

Within a minute, the flow of the pump

must be min. 1.3 liter at the voltage of 12
V.

If the flow is not correct, the supply

voltage of the pump is inspected (the flow
decreases by approx. 10%  for a 1 V
voltage-decrease).

When the fuel circuit is opened, any

petrol jet due to residue pressure must be
averted by means of a gauze.

The air-filter is taken apart.
The fuel supply hose is disconnected.
The MOT 1311-04 derivation junction

is connected onto the ramp, then the fuel-
supply channelling is re-connected onto the
junction.

Terminals no. 3 and 5 of the H fuel-pump

relay (located in the engine fuse-box) are
shunted.

Pressure must be 3+/-0.2 bar.

     By applying a 500 mbar depression on
the pressure-regulator, the pressure of the
fuel must be 2.5+/-0.2 bar.
