3-147. FUEL INJECTOR - MAINTENANCE INSTRUCTIONS (Continued).
g. The fuel injector is one of the most important and precisely built parts of the engine. The injection of the correct
amount of fuel into the combustion chamber at exactly the right time depends upon this unit. Because the injector
operates against high compression pressure in the combustion chamber, efficient operation demands that the injector
assembly be maintained in first class condition at all times. Proper maintenance of the fuel system and the use of the
recommended type of fuel filters and clean water-free fuel are the keys to trouble-free operation of the injectors.
