3.4 FUEL SYSTEM
3.4.1 FLOW OF FUEL
(1) Fuel tank (6) Injection nozzle
(2) Fuel fi lter (7) Fuel overfl ow pipe
(3) Fuel feed pump (8) Air bleed bolt
(4) Injection pump (9) Nozzle holder nut
(5) Injection pipe
3.4.3 BLEEDING THE FUEL SYSTEM
Make sure that the amount of fuel in the fuel tank is
suffi cient.
If there is air in the fuel fi lter, turn the fi lter petcock
(1), shown in the fi gure 3.4.2, to the “air” side and
wait until the fuel fi lter port is fi lled with the fuel. (The
port can be filled with the fuel by head pressure
when the fuel tank is full.)

2.
When no more fuel is drawn into the fuel fi lter port,
turn the petcock (1), shown in the fi gure 3.4.2, to
the “ON” position. 3.
The fuel is fed from the fuel tank (1) through the fuel fi lter
(2) to the injection pump (4) by the fuel feed pump (3).
The injection pump force-feeds the fuel through the injec-
tion 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 overfl ow pipes
(7) and returns to the fuel tank.

Loosen the bleeding bolt (8) shown in the figure
(3.4.1), and crank the engine to bleed air. Then,
tighten the bolt again.
If the engine still cannot be started, loosen 1 or 2 injec-
tion pipe holder nuts (9) (figure 3.4.1) and crank the
engine to bleed air.
When the air bubbles are not seen anymore in the
drained fuel, tighten the loose parts and start the
engine.

3.4.2 FUEL FILTER AND BLEEDING
The fuel from fuel tank enters into the fi lter bowl through the
port (a) and passes through the filter element. Then, it is
drawn out through the port (b) and supplied to the fuel feed
pump. The fi lter element collects the particles of 90 microns
(0.0034 in.) or bigger at 20 kPa (0.2 kgf/cm², 3 psi).

The bleeding process could be skipped if fi lling
