6. Tank
The fuel is fed into the system by an electric pump immersed in the tank, which draws in the fuel and
sends it to the filter and then to the fuel injectors.
The fuel supply system is of the "returnless" type, i.e. with only one connecting pipe between the fuel
tank and engine.
This system makes it possible to:
- minimize the possibility of the vehicle catching fire in the event of an accident;
- reduce fuel vapour emissions into the atmosphere.
The fuel pump is enclosed in the cage which also incorporates the fuel pressure regulator, fuel gauge
sender and fuel filter.
The system also has an inertial switch which cuts off the supply from the fuel pump in the event of a
crash.
