Description of system

DESCRIPTION OF SYSTEM

1. Fuel tank
2. Filter
3. Pressure regulator
4. Distributor manifold
5. Electroinjectors
6. Electric fuel pump
7. Fuel level gauge

The fuel supply circuit comprises an electric fuel pump (6) located in the fuel tank (1) which sends the fuel under pressure through a special tube to the filter (2). From here the fuel is sent to the distributor manifold (4) which distributes it to the electroinjectors (5). The fuel in excess returns to the fuel tank via a special tube, through the pressure regulator (3) fitted directly on the distributor manifold and controlled by the vacuum withdrawn from the intake box. The amount of fuel injected depends solely on the injection time which is controlled by the control unit.

The different sections of the fuel pipes are connected by special connectors (for their disconnection see specific paragraph).

The fuel supply system is fitted with an inertial switch which is triggered in the event of a crash, cutting off the connection to earth of the fuel pump thereby also the injection system supply.

Notes on serviceable fuels: correct operation of the engine requires the use of unleaded fuels (95 R.O.N.) as the presence of lead would quickly bring about consumption of the catalytic converter at the exhaust.
