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 below the fuel filter in line with
the drain plug (4) to collect the fuel.
- Open the drain plug (4) and the bleeder connection (1)
and drain any residual fuel.
- Remove the filter element (3) by unscrewing the relative
bell-shaped support (5).
- Replace the filtering element (3) and the O-ring seal (2)
inside the bell housing support (5).
- Grease the O-ring seal (2) of the filter.
- Insert the filter element (3) and tighten the relative bell-
shaped support (5) to the torque indicated in the table.
Tighten the drain plug (4) to the torque indicated in the table.
Do not fill the new filter until it has been positio-
ned on the support: this prevents allowing impuri-
ties to enter and damage the circuit and injection
system.
Ref. No. Description Torque
3 1 Fuel filter 32.5 ±2.5 Nm

- 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.

No. Description Torque
1 1 Prefilter bleeder screw 18 ±2 Nm
3 1 Fitting for bleeding 17.5 ±2.5 Nm
- 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.
Dispose of consumable materials and the parts in
contact with them (for example filters) in accor-
dance with the law.
