REFERENCE INFORMATION
-4
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 back 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.
I
Replace fuel lines (para. 3-26).
Poor starting and excessive
smoke after
start-up can be the result of a restticted
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 also be affected.

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 noules.
