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
1
2
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.
