Only proceed when the engine is not turning and is at low
temperature so as not to run the risk of burns.
- Close the tank cock.
- Place a suitable container for collecting the fuel under the
fuel prefilter next to the bleeder plug or, if present, the
water presence sensor (2)
- Remove the filter cartridge (1)
- Moisten the O-ring seal (3) of the new filter with oil.
- Screw the cartridge by hand until it comes into contact
with the support and then tighten it to the torque indica-
ted in the table.
- Reconnect the lower electric connection of the water
presence sensor, if present.

No. Description Torque
1 1 Fuel pre-filter cartridge 19.5±1Nm
Do not fill the new prefilter until it has been posi-
tioned on the support: this prevents allowing im-
purities to enter and damage the circuit and injec-
tion system.
Dispose of consumable materials and the parts in
contact with them (for example filters) in accor-
dance with the law.

- Loosen the following bleed connectors connecting them
to the designated pipes to allow the residue to flow into
suitable containers and prevent any soiling:
Screw (1) located on the prefilter support.
Bleeder connection (3) located on the filter support.
- Act on the pump (2) located on the fuel prefilter (provi-
ded by the bodybuilder) until fuel flows out without air
from the bleeder screw (1); upon completion of the ope-
ration tighten the screw.
- Continue to act on the pump until fuel flows out without
air from the bleeder connection (3) located on the fuel
filter; upon completion of the operation tighten the sc-
rew.
Take utmost care to prevent any fuel from soiling
the control belt
- Tighten the bleed screws to the prescribed torque.

- Start the engine and let it run idle for a few minutes to
expel any residual air in the circuit.
For the engine to function correctly the fuel cir-
cuit must be free from air.
