FUEL SUPPLY CIRCUIT DIAGRAM

1. Injectors
2. Fuel supply manifold
3. Fuel delivery line to injectors
Fuel is supplied to the system via an electrical pump submerged in the tank. This takes up fuel and sends
it to the injectors.
The fuel feed system is returnless, i.e. only one pipe connects fuel tank and engine.
This system:
- minimises the possibility of vehicle fires in the case of an accident;
- reduces fuel vapour emissions into the atmosphere;
The electric fuel pump is enclosed in a basket. This also houses the fuel pressure regulator, fuel level
gauge and fuel filter.
The system is also fitted with an inertia switch. This cuts off fuel flow from the electric fuel pump in the
case of vehicle impact.

NOTE Due to the specific shape of the
tank, when fuel is added, an air lock
may build up at the bottom which
could prevent complete filling. Pipe
(4) allows air to flow from the lower
part so that the tank can be filled
completely.
