WARNING
The fuel must be clean and must not contain
any water or any erasive liquids.
Fuel pipes must best made of black pipe, not
galvanized pipe.
When the engine stops, there should not be any
gravitational free flow in the fuel pipes towards
of the engine.
The fuel temperature is a critical factor for
appropriate working conditions of the engine.
Fuel temperature above 71°C, due to expansion
of the fuel, will decrease the engine output
power.
The connection pipe from the bulk storage tank
to the day tank must be equal or greater than
the daily feed pipe.
In fuel system line, using the water filter
seperators will prevent the injectors and fuel
pump, and it will be usefull for healthy working
of the engine.
In the simplest tank settlement, the fuel level
should not be above the injectors and should
not be lower than the fuel pump for more than
1.8 m, see Figure 4.7.

If the fuel tank is set 1.5 meters above injectors,
two check valves must be connected like in
Figure 4.8 in order to prevent the engine from
hydraulic lock. The protection capacity of these
valves is 0 to 1.5 meters in elevation. If fuel tank
will be mounted at an elevation and at a distance,
Figure 4.10 shows a tank mounted below the
engine level and at a distance.
