Cleaning Fuel Filter
This job should not be done in the field, but in a clean place.
1. Close the fuel filter cock (1).
2. Unscrew the screw ring and remove the fuel filter bowl (2), and
rinse the inside with kerosene.
3. Take out the filter element (4) and dip it in the kerosene to rinse.
4. After cleaning, reassemble the fuel filter, keeping out dust and
dirt.
5. Bleed the fuel system. (See page G-28.)
IMPORTANT
■
• If dust and dirt enters the fuel system the fuel pump and
injection nozzles are subject to premature wear. To prevent
this, be sure to clean the fuel filter bowl periodically.

Checking Fuel Line
CAUTION
• Stop the engine when attempting the check and change
prescribed below.
• Remember to check the fuel line periodically. The fuel line
is subject to wear and aging, fuel may leak out onto the
running engine, causing a fire.
1. Check to see that all line and hose clamps are tight and not
damaged.
2. If hoses and clamps are found worn or damaged, replace or
repair them at once.
3. The fuel line is made of rubber and ages regardless of period of
service. Replace the fuel pipe together with the clamp every two
years and securely tighten.
4. However if the fuel pipe and clamp are found damaged or
deteriorated earlier than two years, then change or remedy.
5. After the fuel line and clamp have been changed, bleed the fuel
system. (See page G-28.)
IMPORTANT
■
• When the fuel line is disconnected for change, close both
ends of the fuel line with a piece of clean cloth or paper to
prevent dust and dirt from entering. Entrance of dust and
dirt causes malfunction of the fuel injection pump. In
addition, particular care must be taken not to admit dust and
dirt into the fuel pump.
