Howdy folks, I am new here, just got in a reltaionship with a 68 220D.

anyway, the injection pump seems to keep losing oil and leaking fuel and it trys to runaway when i overfill it. anyone can suggest a good book, or know how to go about refurbing this pump. i wouldn't really know what the proper names of the parts and seals are i need .
many thanks, jon
