FUEL SYSTEM.
a..
Identical fuel systems are Installed, port and starboard. The fuel system supplies fuel oil for operating the
propulsion engines. When the system is lined up for operation, fuel oil flows from the fuel tanks through the suction
valves In the lazarette into the engine room. Two supply valves located In the engine room near bulkhead 39 (on both
sides of the ramp/starting system hydraulic tank) allow fuel oil to flow Into the fuel strainers The cross-over line located
ahead of the supply valves permits fuel oil to flow from the port fuel tank through the starboard fuel oil strainer to the
starboard engine, and vice versa. The fuel oil is further purified as It flows through the fuel filter/water separators before
going to the engines. Fuel oil not Injected into the engine is cooled In the fuel oil coolers before returning to tank. Fuel
oil from either engine may be returned to either fuel oil tank through the return valves In the fuel oil return piping The
relief valve in the return piping relieves directly to the starboard fuel oil tank when the pressure In the return lines
exceeds 2 psi. The engine mounted fuel filter, fuel pump, and fuel manifold which complement the system are covered
in TM 5-2815-231-14.
