3.4 FUEL SYSTEM
3.4.1 FLOW OF FUEL
The fuel is feed from the fuel tank (1) through the fuel
filter (2) to the injection pump (4) by the fuel feed pump
(3). The injection pump force-feeds the fuel through
the injection nozzles (6), which inject the fuel into the
cylinders for combustion. Any excessive fuel from the
injection pump to the injection nozzles is collected in
the fuel overflow pipes (7) and returns to the fuel tank.

3.4.2 FUEL FILTER
A fuel filter is used to prevent dirty fuel from reaching
the injection pump and injection nozzles. The filter ele-
ment will require occasional replacement to maintain
an adequate flow. This flow will vary according to the
cleanliness of available fuel and the care used in
storage.
The fuel filter between the tank and pump to eliminate
foreign matter and protect injection pump and nozzles
filters fuel pumped by the fuel pump from the fuel tank.
When fuel enters the filter, it passes through the filter
element’s circumference toward the center for filtering.
The maximum filtrated granular size of this element is
48 µm (0.048 mm, 0.0019 in.) and general size is form
10 to 20 µm (0.01 to 0.02 mm, 0.0004 to 0.0008 in.).

3.4.3 AIR BLEED BOLT
1. Check the fuel level in the fuel tank and fill the tank
with fuel if necessary.
2. Check the fuel level in the fuel filter is 2/3 or higher.
If not, loosen the air bleed bolt (8) and crank the
engine to bleed the system.
3. When air stops bleeding, tighten the air bleed bolt
and crank the engine.
4. If the engine still fails to start, loosen the nozzle
holder nut (9) or injection nozzle nut (6) and crank
the engine to bleed the system.
5. Tighten the loosened nut and start the engine.
