PUMP CAPACITY CHECKING
SPECIAL TOOLS
Pliers for “CLICK” collars.
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).

FILLING CAP
Fuel tank
The fuel tank is having a filling cap, sealed-type, with key. The filling cap for unleaded fuel has
a filler whole incompatible with a c lassical filling gun (lead has a negative effect upon the de-
pollution system : oxygen sensor and catalyst).
In case of vehicle overturning, the anti-overturning valve is getting blocked, avoiding in this
wa y, the petrol leakage towards the carbon can.

DISMOUNTIN G
Drain the fuel tank ( 4)
Disconnect the battery.
Remove the trunk carpet.
Di smount the tank visiting cover from the
three attachment screws.
Di sconnect the e lectric connector f the fuel
pump assembly a nd detach from clips the
connection from the fuel supply pipe. Take out the spare wheel and release it
together with its support.
Remove the filling cap ( 2) and dismount the
two attachment screws of the upper filling cap.
Lift the vehicle on a two columns elevator.
Dismount the four-attachment screws (6) of
the fuel tank on the carriage body, then maintained
in tilted position, disconnect the rapid coupling
on the anti-overturning valve ( 7).
D etach from clips collar ( 3) of the aerating
pipe on the upper filling cap.
Release the fuel tank together with the aerating
connection. Dismount the thermal screen ( 5) off the three
maintaining clips. Dismount the attachment clip ( 1) of the filling
cap muff on the lower filling cap.
Dism ount t he fue l pum p a sse mbly by
dismounting the attachment nut by means of the
MOT 1397 device.
REMOUNTIN G
Perform the dismounting operatio ns in the
reverse order. The t ightening moment of t he fuel tank
attachment screws on the carriage body is of
2.1 daNm and the tightening moment for fuel
pump assembly attachment nut, is of minimal
7daNm .
REMARK :
Collar (1) is for single use only.
When remounting, use a new click collar
(1 ), for the attachmen t of the lower filling cap
connection on the fuel tank.
REMARK:

IMPORTANT :
Dur ing thi s operation it is
compulsory:
-not smoking and not approaching
with i ncandescent obj ects in t he working
area, -keep awa y from fue l spray i ng
when disc onn ectin g the fu el

- filling cap attachment clip (5) on tank;
- fuel pump assembly (6).
REMOU NT I NG
Perform the di smounting opera tions in the
reverse order.
Tighten to the required moment the fuel tank
attachment screws (2.1 daNm); the thread of
the two rear attachmen t screws is to be lubricated
before mounting with Fixamed M28 (necessary
quantity – 2 grams).

Dismount the fuel tank cap.
Drain the fuel tank through the filling cap,
by means of a draining pneumatic or electric
pump. Dismount the a ttachments screws ( 1) of
the upper filling cap.
Lift the vehicle by means of the elevator.
Di smount the four attachment screws of
the fuel tank. Dismount the attachment clip ( 2) of the
aeration hose ( 4) on filling cap.
Carefully lower the tank and disconnect it:
- wiring connector;
- fuel supply pipe;
- petrol vapors re-aspiration pipe (for
petrol engines); - fuel return pipe (for Diesel engines);
Extract the aera tion hose on top of tank
crossbar and dismount the tank.
