In the engine compartment, disconnect the fuel
pump relay (identifiable as it has larger section
wires , 5 mm
2 , on tracks 3 and 5) located in the
engine connection unit.

DRAINING THE FUEL TANK (diesel version)
As there is no electric fuel pump, a pump must be
used to drain the fuel tank.
Use for example:
- the INTAIRCO pneumatic pump (see
EQUIPMENT 95 catalogue),
B - Fuel relay
Shunt tracks 3 and 5 and allow the fuel to run out
until it is only pumped out intermittently.
Disconnect the shunt.
Reconnect the relay.
Disconnect the battery.- piston pump 333. Refer to your After Sales
Head Office for more details.

FUEL TANK
Gauge

For petrol engines, the pump and gauge sender
unit are an inseparable assembly.
For diesel engines, there is no pump submerged in
the fuel tank, there is only a gauge sender unit.
For removing the gauge sender unit refer to the
section FUEL TANK "Pump - sender unit".
Checking the gauge sender unit
Ensure the resistance varies by moving the float.

SPECIAL TOOLING REQUIRED
IMPORTANT :
During all operations on the fuel tank or fuel sup-
ply circuit, it is vital to:
- avoid smoking and keep all heat sources away
from the working area,
- take precautions against fuel splashes due to
the residual pressure in the fuel pipes when
they are removed.
REMOVAL
The fuel tank does not need to be removed to re-
move the pump and sender unit assembly. It may
be reached from inside the vehicle as follows :
- disconnect the battery,
- lift the rear bench seat,
- remove the plastic cover,
- disconnect the electrical connector (1),
- remove the clips (2).
