IMPORTANT:
During the int erventi on on the fuel tank
and on the fuel supply circuit, at t he working
place, do not smoke and do not bring near
an y incandescent parts.
Fuel tank draining i s not implying tank
dismountin g. The access is allowed through the
vehicle interior (trunk).
Dismo unt :
-tr unk carpet;
-v isitin g whole cover (by dismounting the
three attachment screws);
- disconnect the rapid coupling A;
- adjust to exit A, an enough long hose to
be introduced in a vessel outside the vehicle.
From the fuse box located inside the engine
compartment, remove the H relay of the petrol
pump and bridge across plugs 3 and 5 of the
relay connector, ensuring the petrol pump
working (12V).
Stop the pum p working when petrol
discontin uous draining s noticed.
Detach the plugs bridge.
