The gasket between the top half with the fuel pin it is leaking fuel out of the injection pump I’ve never been inside of a injection pump before but I’ve been in places in a hydraulic system I probably shouldn’t of been is this a job I can do or should I pay to a professional have the pump resealed?

 

Did you check the "Stickies"? There's several "how to's" in there on the IP.

 

In the Stickies at the top of the page under engines Jim Lane has an excellent article on fixing your problem.
