I know that the 7.3 uses the Caterpillar HEUI Injection system. Does anyone know if the 6.0 adopted the HEUI as well. I have heard on several ocations that it uses the common (high pressure) fuel rail systemlike the durimax and the ISBE cummins, but also heard on other ocations that it still uses the HEUI system. Does any one know?

 

this might help ....

Go to the tech folder and read the 6.0 L bible, it will explain what you are asking and much much more, it did for me.
