and detach the pump.
3. Undo the nuts fixing the exhaust manifold
to the cylinder head and detach the mani­
fold.
- To refit, reverse the order of the operations
carried out for the removal; tension the
power assisted steering pump drive belt,
using the adjustment screw; use tool
189576200 to check that the tension is
between 32 and 45 daN.
ELECTRIC FUEL PUMP WITH LEVEL
SENDER UNIT
Removing-refitting
- Disconnect the negative battery terminal.
- Lift up the lining in the luggage compart­
ment and remove the fuel pup protective
cover.
- Disconnect the electrical connection for the
electric pump assembly and the fuel supply
and breather pipes.
4. Undo the ring nut fixing the electric fuel
pump to the tank using tool 1870736000.
The gasket on the tank housing should be
replaced each time the pump drip tray is
removed-refitted.

and is established by a reference in
the housing in the tank which sou Id
correspond to the projection on the
pump drip tray.

SOLENOID VALVE ON VACUUM RES­
ERVOIR FOR THROTTLE CASING
PNEUMATIC VALVE
Removing-refitting
- Disconnect the negative battery lead, then
remove the sound insulation shield follow­
ing the instructions in the previous para­
graphs.
1. Disconnect the electrical connections (1)
at the fuel filter and the supply and return
pipes (2) at the reservoir and the supply
pipe to the pump, then loosen the nuts (3)
fixing the fuel filter mounting. Lift up the
filter and disconnect the electrical connec­
tion (4) for the water in the diesel sensor.
- Release the power assisted steering fluid
supply pipe from the reservoir to the pump
from the retaining band.
2. Disconnect the pipe (1) connected to the
vacuum reservoir and the pipe (2) con­
nected to the vacuum intake pipe from the
solenoid valve. Disconnect the electrical
connector (3), then undo the fixing bolts
(4) and remove the solenoid valve.
VACUUM RESERVOIR
Removing-refitting
- Disconnect the negative battery lead, then
remove the sound insulation shield and the
fuel filter, following the instructions in the
previous paragraphs.
- Release the power assisted steering fluid
supply pipe from the reservoir to the pump
from the retaining band.
3. Disconnect the pipe (1) connected to the
vacuum reservoir and the pipe (2) con­
nected to the vacuum intake pipe from the
solenoid valve. Disconnect the electrical
connector (3), then undo the fixing bolts
(4) and remove the bracket, complete with
solenoid valve, for the throttle casing
pneumatic valve.
