Tractor Repair: 574 tractor, oil dipstick, diesel injection

Question
I have a international 574 tractor. There is diesel fuel going into the oil. Oil dipstick confirms this. It is flowing out the overfill. I heard there is a o ring on fuel pump that is the problem. Is fuel pump on right side behind where filters hook up or on the left side where the fuel pump sits on the outside?? Guess thats a dumb question but would rather be sure before I start unhooking stuff.. thanks  

Answer
  Hello,

  The injection pump is on the left side.  The pump will probably have to be sent into a diesel injection repair facility.  I would change oil twice after getting it repaired.  Once before you start it, and then again after running it for about 10 minutes to make sure all the fuel is flushed out of the engine.
