CHECKING FUEL LINES
(1) Fuel Pipe (2) Fuel Hose Clamp
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 ser-
vice. Change the fuel pipe together
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.
4. After the fuel pipe and hose
clamps have been changed, bleed
the fuel system.
WARNING
• Stop the engine when checking
the items above.
• Inspect the fuel pipe regularly.
The fuel pipes are subject to
wear and aging. Failure to per-
form periodic inspections may
lead to a fuel leak. Fuel leaking
on a hot engine could cause a
re.
