KB CHECK ANTI-EVAPORATION SYSTEM
The anti-evaporation system prevents the petrol vapours, which form in the tank and the fuel system,
from being discharged into the atmosphere and consequently releasing the light hydrocarbons (HC)
which they contain, producing a pollutant effect.
It is therefore necessary to check that the anti-evaporatin system pipes are correctly positioned in the
engine compartment; also check their condition, making sure that there are no signs of cracks, cuts or
leaks and that they are correctly fixed and not interfering with other components. Check the condition
of the active charcoal filter. Position the vehicle on a lift and check the condition of the pipes under the
floo of the vehicle.
fQ REPLACE FUEL FILTER (petrol engines)
Proceed with removing the fuel filter by car­
rying out the following operations:
- Raise the vehicle;
- undo the bolts shown in the diagram and
remove the protective shield.
- disconnect the rapid fue inlet and outlet
connectors from the filter, collecting the fu­
el which comes out during the operation in
a suitable container.
- undo the fixing bolt and remove the filter.
NOTE The filter should NEVER BE FITTED
THE WRONG WAY ROUND, or else
it has to be replaced (even after
working in the wrong position for a
short period). The arrow on the out­
er casing indicates the direction in
which the fuel should flow.
After replacing the filter, start up the
engine and check that there are no
leaks of fuel from the seals.
