Section 5 Fuel System
Explosive fuel vapors.
Can cause severe injury or death.
Use extreme care when handling,
storing, and using fuels.
WARNING
Note: Do not modify the tank or the propulsion engine
fuel system. Equip the craft with a tank that
allows one of the two pickup arrangements.
Note: Fuel system installations must conform to USCG
Regulations.
Note: Use pipe s ealant on all threaded fittings to
prevent fuel leakage. Use pipe sealant that
resists gasoline, grease, lubrication oil, common
bilge solvents, salt deposits, and water.
5.1 Fuel Tank
Most marine generator sets draw fuel from the same fuel
tank as the craft’s propulsion engine(s). If the tank’s fuel
pickup opening allows a multiple dip tube, use a multiple
dip tube arrangement. See Figure 5-1. The multiple dip
tube arrangement incorporates a shorter dip tube for the
generator set and a longer dip tube for the propulsion
engine. With this arrangement, the generator set runs
out of fuel before the propulsion engine during a low fuel
supply situation. Equip the fuel system with a fuel/water
separator to remove any accumulated dirt and water.
