7.1.4 COMPLETE REMOVAL OF THE FUEL TANK
Carefully read 0.4.1 (PRECAUTIONS AND GENERAL
INFORMATIONS), 1.2.1 (FUEL) and 4.1 (FUEL TANK).
Fuel vapours are noxious for your health.
Before proceeding, make sure that the room in which'
you are working is properly ventilated.
Do not inhale fuel vapours.
Do not smoke and do not use naked flames.
Do not dispose of fuel in the environment.
RISK OF FIRE ANDIOR EXPLOSION.
• Drain the tank of petrol, see 2.9 (DRAINING THE FUEL
TANK).
• Partially remove the tank, see 7.1.3 (PARTIAL RE-
MOVAL OF THE FUEL TANK).
• Turn the tank upside down.
Place a cloth under the perforated screw (1) to catch
any fuel spills. , '
Fuel tank perforated screw (1) driving torque: 22 Nm
(2.2 kgm).
• Loosen the perforated screw (1) by approx. half a turn
and wait a few seconds to allow the system to depres-
surize.
• Unscrew and remove the perforated screw (1) and take
the
two
gaskets (2).
CHASSIS
Upon reassembly, change the two gaskets (2) and
tighten the perforated screw (1) applying the pre-
scribed torque in order to ensure perfect seal. This is
essential, since the injection pressure is approx. 450
kPa (4.5 bar) and any fuel leakage would prove ex-
tremely dangerous, in fact the leaking fuel might end
up on high-temperature parts of the engine..
When reassembling, a special seat (3) indicates the
correct direction in which the 'pipe (4) must be
placed.
The' fuel delivery pipe (4) must not be entangled or
positioned where it is likely to be squashed by other
components; should it appear damaged or deteriorat-
ed, it must be replaced.
• Remove the tank completely.
• If the lower acoustic insulation edging at the front and
lower antiheat edging at the rear prove damaged, re-
place them.
