Default injection pump leak...

any ideas on where this leak is coming from? its between the head of the pump and the timing case. the highern the rpms the more fuel that leaks out.. its driving my crazy. Im to the point where i think that i might have to pull the pump out to fix it, and really not looking foward to that

it looks like its the line coming from the front of the pump and goes down to the side, near the fender well. My old mans buddy side it was a timing advance for those colder days. im not to sure on it though, but it sure is leaking fuel from there like crazy.
