FUEL SYSTEM - Continued
Figure 3.
Surplus fuel from injectors is returned to the fuel tank (1) through the return line (7).
NOTE
The fuel/water separator removes water and large solid particles from the
fuel.
The finer particles are removed by the secondary filter (5) before they can enter the fuel
injectors.
COOLING SYSTEM
NOTE
The pressure type cooling system protects the engine by removing heat
generated during the combustion process.
Pressure within the cooling system is regulated by a pressure release in the radiator filler
cap (1).
