466 International fuel leak

I have a fuel leak on the #4 injector on the 466 IH in my combine. Fuel leaks up around the dust cap on the injector. I pulled the injector, cleaned the cup and installed a new copper gasket at the base of the injector with no improvement. What am I looking at here?
 
leave the dust boot off, and clean injector body with brakekleen (or Ether). Run the engine, see if it is leaking from the body of the injector. Usualy it is the fuel line though, Mark
 
The injector has a spacer plate between the body and tip assembly, one or both lapped surfaces could be leaking, allowing fuel to seep up past the dust seal. Not common, but can happen. A special clamping tool is used when removing the tip nut, or the dowel pins will shear that locate the proper tip spray angle.
