Generator sets, in most cases, must draw fuel from the
same tank as the propulsion engines. If the tank’s fuel
pickup opening allows, a multiple dip tube arrangement
(Figure 6-6) may be used. An alternate tank, if used,
should have a smaller separate pickup opening allowing
a single dip tube (Figure 6-7).

For installations where the highest point of the gasoline
source (fuel tank) is above the generator set carburetor,
an auxiliary fuel shutoff valve is required. This fuel
shutoff valve should be closed when the generator is not
in use to prevent fuel leakage resulting from fuel flow
through the fuel pump and into the carburetor should the
float valve not seat properly.
NOTE
Fuel systems must conform to U.S.C.G Regulations and
tests.
WARNING
Explosive fuel vapors.
Can cause severe injury or death.
Use extreme care when handling, storing,
and using fuels.
Explosive fuel vapors can cause severe injury or
death. Fuel leakage can cause an explosion. Do not
modify the tank or propulsion engine fuel system. Craft
must be equipped with a tank allowing one of the two
pickup arrangements described. Tank and installation
must conform to U.S.C.G. Regulations.
