3.6 Fuel system
The fuel line is controlled by the Fuel Box Unit (FBU), which, through the various signals
acquired and processed by the Electronic Control Unit (ECU), is able to regulate the amount
of fuel to be injected in each operating condition.
As soon as the ECU is switched on, several checks are performed automatically and the fuel
line is filled without the need for manual priming.
The entire fuel system that will be described in the following paragraphs can become very
dangerous in case of improper installation. In fact, all the components that make up the
system can pose a hazard in the event of a pressurized fuel leak. Extreme care is
recommended in operations and to follow instructions scrupulously.
Always keep the fuel hoses and their connections protected with a cap when they are
disconnected. Remove the caps only when connecting them.
The entry of impurities into the fuel system can impair the functioning of the circuit
components and lead to serious hazards.
The use of non-original Vittorazi components can involve severe risks.
In case of occlusion of a component inside the FBU, it will be necessary to replace the Full
Integrated Unit (FIU) and ship the defective one to the Vittorazi headquarters (See
maintenance manual chapter 3.5 Full integrated unit (FIU)).
