Section 5 Fuel System
5.1 General
In most installations, both the generator set a nd the
propulsion engine operate from a common fuel t ank with
a dual dip tube arrangement. The generator set’s dip
tube is shorter than the propulsion engine’s dip tube.
With this arrangement, fuel may not be available to the
generator set when the fuel supply is low. See
Figure 5-1 for a fuel system schematic.
