COOLING - EXHAUST - TANK

Safety valve ( over pressure, depression)

In case recycling circuit of the petrol vapors is clogged, this valve is avoiding the over-pressure

(inflated tank) or the depression (by fuel consumption- the tank is flattening).

Restrictor

Does not  allow leaded fuel filling in the tank.

Anti-overturning valve
In case of vehicle overturning, this is avoiding the fuel leakage through the pipe leading to the

carbon can.

IMPORTANT
During the intervention on the fuel tank or on the

fuel supply circuit, it is absolutely necessary:

- not smoking and not bringing near any incan-

descent parts in the working area;

- guard against possible petrol leakage, due to

residual pressure  remained  on  piping,  when
dismounting.

DISMOUNTING

In order to dismount the fuel pump assembly it is

not necessary the tank dismounting, the access being
done through the vehicle trunk.

In order to do that:
- disconnect the battery;
- dismount the attachment screws of the fuel

tank visiting cover;

- disconnect the electric connector (B) of the

fuel pump assembly supply;

- disconnect the rapid coupling (A) of the fuel

supply pipe.

Dismount the fuel pump assembly (2) attachment

nut (1), by means of the MOT 1397 device, after

previously marking on the fuel tank the position of
the arrow existing on the pump cap.

Release the fuel pump assembly.

REMOUNTING

Mount the fuel pump assembly on the fuel tank

observing the marking done when dismounting.

Mount the attachment nut of the fuel pump

assembly.

Tighten the nut by means of the MOT 1397

device, so that the arrow from the nut meets the
arrow from the fuel pump assembly (this is ensuring
the minimal necessary tightening for sealing
achievement.

REMARK :
After each dismounting, obligatory

replace the nut and

 its gasket.

The gasket will have the same color with the
dismounted one.

In order to dismount the  fuel pump as-

sembly,  it is necessary the fuel tank dis-
mounting.

IMPORTANT
During this operation it is compulsory:

- not smoking and not approaching

with incandescent objects in the working
area,

- keep away from fuel spraying when

disconnecting the fuel connections,

- protect the sensitive  area of  fuel leak.

DISMOUNTING

Dismount the fuel tank.
Dismount the attachment nut of the fuel pump

assembly by means of the wrench MOT 1397.

Dismount the fuel pump assembly

ATTENTION!
When dismounting the nut, take care that

fuel pump assembly is not geared in rotation
with the nut, which may lead to float rod
distortion and consequently to fuel level
wrong indication.

Remark:
If until fuel pump mounting on tank,

more than  an hou r is  taken in to
consideration, remount the nut on the
tank, in order to avoid any distortion.

REMOUNTING

Replace the sealing gasket of the fuel

pump assembly. The gasket shall have the
same color  with the dismounted one.

Mount the fuel pump assembly so that

arrow (1) from the fuel pump assembly is
corresponding to the arrow (20 from the
tank.

Position the nut and tighten it by hand to

maximum possible, preventing the pump
assembly rotation.

Tighten the nut by means of the MOT

1397 wrench until arrow (3) from the nut is
aligned with the marks from fuel tank and
pump assembly.

Fuel filter

For de-pollution norm 1504
The fuel filter is attached on the front side of the fuel filter.
It is recommended, the fuel filter replacement, every  20 000 Km.

For EURO 2  and EURO 3

The fuel filter is mounted on the fuel pump assembly placed in the fuel tank.
Its replacement is implying the replacement of the entire fuel pump assembly (1).
