3-89.2. FUEL INJECTOR TUBE - MAINTENANCE INSTRUCTIONS
The bore in the cylinder head for the fuel injector is directly through the cylinder head water jacket. To
prevent coolant from contacting the injector and still maintain maximum cooling of the injector, a tube is
pressed into the injector bore. This tube is sealed at the top with a neoprene ring and set into a flare on the
lower side of the cylinder head to create water-tight and gas-tight joints at the top and bottom.
