Leaking where?
The only possible leaks are the return plastic tee or the high pressure line, unless the injector body is cracked.

This thread goes into some detail, but, I can assure you that it is not the copper seal or the body O-ring. Those only stop combustion gas leakage and keep dirt from the injector hole machined into the head.
