14 - 38 FUEL SYSTEM : •
Fig. 10 Fuel Injector Internal Components—Typical
valve ports of the cylinder head. The engine wiring
harness connector for each fuel injector is equipped
with an attached numerical tag (INJ 1, I N J 2 etc.).
This is used to identify each fuel injector with its re­
spective cylinder number.
