REFERENCE INFORMATION
Fuel lines should be inspected for
kinks, cracks or anything that would
restrict fuel flow or allow air to enter
the lines. Be sure to check the lines
all the way beck to the tank and
remember that there is a strainer
inside the tank which can become
plugged. You will have to remove
the tank if it becomes necessary to
check this.
Replace fuel lines, refer to
(para 3-25)
Poor starting and excessive smoke after
start up can be the result of a restricted
fuel supply. This restriction most likely will
be from a plugged fuel filter but can also
be caused by a pinched or kinked fuel line.
After the engine warms up, it generally will
run satisfactorily. If the restriction gets
progressively worse, top speed and
performance will be affected also.
FUNGUS
In warm or humid weather, fungi and/or
bacteria in the fuel can cause fuel system
damage by plugging the fuel lines, filter, or
injection nozzles.
For removal, replacement and torques,
refer to (para 3-33) or notify DS
maintenance.
Excessive roughness on any of these
parts is an indication of wear. The
pushrod should slide smoothly in the
engine block. If you notice any
roughness on the end of the pushrod
be sure to check the lobe on the
camshaft.
NOTE
If the pump or rod is worn, replace.
Refer to (para 3-23). If the lobe
on the camshaft is worn, notify
DS maintenance.
Rerun Test Chain
You may have corrected some
problems but there may be others
including the fuel pump.
For removal, replacement and torques,
refer to (para 3-23).
