TM 10-3930-664-10 1-15. FUEL SYSTEM FUEL TANK.  Contains diesel fuel for operation of the engine.  Holds approximately 27 gallons (102L) of fuel, enough for 10 hours of operation. SHUT-OFF VALVE.  Blocks the flow of diesel fuel from the fuel tank to the fuel lift pump when the valve handle is parallel to the side of the fuel tank.  The valve handle must be perpendicular to the tank for normal fuel flow. WATER SEPARATOR.  Removes moisture from the fuel. FUEL LIFT PUMP.  Pulls fuel from the fuel tank through the water separator, and sends it through the fuel filters to the fuel injection pump.  Mechanically operated by the engine camshaft. FUEL FILTERS.  Removes dirt or other contaminants from the fuel before it reaches the fuel injection pump. FUEL  INJECTION  PUMP.    Pressurizes  the  diesel  fuel  and  sends  an  exact  amount  of  fuel  to  the  fuel  injector  nozzles. Controls sequence and timing of cylinder combustion. FUEL  INJECTOR  NOZZLE.    Turns  the  stream  of  fuel  into  a  fine  spray  which  permits  good  combustion  in  the  cylinder. There is one nozzle for each cylinder. AIR CLEANER.  Removes dirt and dust from intake air prior to its use in combustion. 1-9
