parking brake.
2. open the hood and remove the
left side cover.
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.

Stop the engine when check -
ing the items above.

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
fire.

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 sys -
tem or injection pump. Pay ex -
