EE] C H E C K ANTI-EVAPORATION S Y S T E M

The anti-evaporation system prevents the petrol vapours, w h i c h 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 w i t h 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.
