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:
Connect draining lines without fail, otherwise emerging
WARNING:
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.
