LOCATION AND DESCRIPTION OF MAJOR COMPONENTS AND SYSTEMS (CONTINUED)
The upper and lower fuel cells have a combined capacity of 135
gallons of fuel oil. Fuel oil is pumped from the cells, by two
submerged electrically driven fuel pumps, to a fuel distribution ter-
minal where it is routed to the personnel heater, APU fuel pump
and filters, primary fuel filter or returned to the fuel cell.
The primary fuel filter receives fuel from the fuel cells. The main
engine driven fuel pump pulls fuel from the primary fuel filter and
channels it to the secondary fuel filter.
Fuel is delivered from the secondary fuel filter to the engine. The
fuel return cross-over hose carries fuel from the right to the left
cylinder head. Unused fuel from the engine is routed through the
fuel return hose for delivery to the flame heater system, or returned
to the fuel cells. The engine mounted electric fuel pump is activated
by a switch on the drivers instrument panel, and allows flow of fuel
from primary to secondary filters when the engine is not running.
