The fuel filter consists of an internal filtering-paper cartridge
(13) and is equipped with a water separator.
The maximum water storage capacity of the filter is 150 cm
The water sensor detects the presence of water in the filter
starting from an existing volume of 70 cm
This sensor is located in the lower part of the filter.
The temperature, water and clogging (if any) sensors are
interfaced with the electronic circuit (11) located inside in the
upper portion of the assembly.
When the diesel fuel temperature is lower than a limit value,
the electric resistor will come into operation by properly
heating the diesel fuel before the latter is conveyed to the
high-pressure pump.
Clogging sensor (if any) features:
- differential working pressure: 0.7 to 0.85 bar

NOTE
Due to the very high pressure existing within this hydraulic system, the following precautions shall be taken for safety
reasons:
- avoid connecting the high-pressure pipe fittings by means of makeshift fasteners: tighten them to the specified
torque;
- avoid disconnecting the high-pressure pipes when the engine is running (DO NOT make any attempt at draining:
this is absolutely useless and dangerous
To ensure correct operation of the system, it is essential that the low-pressure circuit is intact. Therefore, any modification
or attempt at tampering shall be avoided, and corrective actions shall be taken immediately in case of leaks.
In the event that fuel pipes (1-2-3) are disconnected from support (1), make sure, when reattaching the pipes, that their
respective fittings are fully clean.
Such precautions shall be taken to avoid detective sealing, with resulting fuel leaks.
