FUEL TANKS AND DISTRIBUTION SYSTEM. Two aluminum fuel tanks, one on either side of
engine compartment, are interconnected by a flexible cross-feed hose fitted with a butterfly
valve. Hose and valve are located beneath turret subfloor. Twelve stainless steel fuel lines
carry fuel under pressure from fuel pumps on fuel tanks to fuel injector nozzles in each cylinder
head. Fuel leakage from nozzles is carried through fuel return tubes on each cylinder back to
fuel return system to fuel tanks. Flexible fuel hoses and tubing are interconnected to carry fuel
to powerplant and personnel heater. Electric fuel pumps in each tank force fuel through fuel
lines to engine fuel system. Backflow valve between engine fuel pump and primary fuel filter
retains fuel in engine fuel lines when engine is shut off.
