Fuel Supply

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.
