FUEL SYSTEM
In a normal installation, fuel is drawn out of the fuel tank
through the primary "water/separator fuel filter" by the engine
driven, diaphram type, Fuel Pump (3/50). From the Fuel Pump it
goes first through the engine Fuel Filter (11/10), then to the Fuel
Injection Pump (3/29).
It is important to know that most of the fuel delivered to the Fuel
Injection Pump by the Fuel Pump, is surplus, and is returned to
the fuel tank. The Fuel Pump is pumping at a rate of approxi-
mately 3.17 gallons per hour. The Fuel Injection Pump will only
use 0.4 of a gallon per hour (when the generator is producing 30
Fuel Filter
amps of electrical power). The high volume of return flow
Fuel Pump
provides a continuous cleaning action of the fuel through the
Fuel Injection Pump
vessel's filter. This will help to keep the fuel in the tank clean.
WATER PUMPS
The Water Pumps are flexible impeller types. Each pump is
complete and independent of the other, except the Raw Water
Pump is "piggybacked" onto the Fresh Water Pump. The shaft
tang of the Raw Water Pump extends beyond the pump housing
and fits into the pump shaft slot of the Fresh Water Pump (21/0).
