16.2.1) Airbox
See Ill. 44.
The airbox is furnished with 2 drain holes at the lowest position possible.
The holes are necessary to drain fuel from flooding float chambers caused
by badly closing float valve.
◆ NOTE: This drain bores are very small (1,5 mm (1/16") dia.).
Compensation of process conditions is taken care of by the
TCU.
Drainage lines:
▲ WARNING: Connect draining lines without fail, otherwise emerging
fuel could drip onto the exhaust system.
RISK OF FIRE!
➪ The lines have to be routed such that in case of damage the surplus fuel
is drained away suitably.
➪ Route the lines without kinks and avoid narrow bends.
➪ Route the lines with a continuous decline.
➪ The lines have to be protected against any kind of blockage e.g. by
formation of ice.
■ ATTENTION: With closed or blocked drainage bores fuel could flow into
combustion chamber, possibly ruining the engine by hydrau-
lic lock.
