CHECKING FUEL LINES(U)
Although checking the fuel pipe con-
nection is recommended every 100
service hours, it should be done ev-
ery 6 months if operation does not
exceed 100 hours in 6 months.
1. If the hose clamps are loose, apply
a slight coat of lubricant onto the
threads and securely tighten it.
2. The fuel pipe is made of rubber
and ages regardless of period of
service. Change the fuel pipe to-
gether with the hose clamps every
two years and securely tighten.
3. If the fuel pipes and hose clamps
are found damaged or deterio-
rated earlier than two years, then
change them immediately.
•
Stop the engine when check-
ing the items above.
•
The fuel pipes are subject to wear
and aging. Failure to perform
periodic inspections may lead to
a fuel leak. Fuel leaking on a hot
engine could cause a re.
WARNING
•
When changing fuel pipes, be
careful not to allow dust or dirt
to enter the fuel system. Con-
taminations in the fuel system
could damage the fuel system
or injection pump. Pay extra
caution to the fuel pump to
prevent dust from entering it.
