DRAINING THE FUEL TANK ( Diesel version)
Since Diesel versions are not fitted with an electri-
cal fuel pump, a manual pump must be used to
drain the tank.
For example, the
INTAIRCO pneumatic siphoning
pump is suitable for this operation (see
EQUIPMENT catalogue),
Shunt tracks 3 and 5 and let the fuel flow until it
runs out in intermittent jets.
Disconnect the shunt.
Reconnect the relay.
Disconnect the battery.Remove the pump-sender unit steel access cover.
Remove the clip which shows if the assembly has
been pushed in (if fitted).
Disconnect the quick release union at (1), tool
Mot. 1265.

SPECIAL TOOLING REQUIRED
IMPORTANT :
During all operations on the fuel tank or on the
fuel supply circuit , it is vital :
- to refrain from smoking and handling incan-
descent objects in the vicinity of the working
area,
- to avoid fuel projections, due to the residual
pressure present in the pipes during removal .
REMOVAL
To remove the pump-sender unit assembly, it is
not necessary to remove the tank, as it is accessi-
ble through the inside of the vehicle. To do this :
- disconnect the battery,
- lift the rear bench seat ,
- remove the steel access cover,
- remove the electrical connection at (1),
- remove the clips at (2).
