I have a leak coming from under my fuel pump ( engine oil). I found a a nut layn' on top of vacum pump that looks like its from the fuel pump on the block side. I can't get in there to see what stud it is off, obviously this is the source of my oil leak. The pumps were change 14 mnths ago and my dealer is doa. Anybody got any suggestions where i can start? 5.9 cummins 3500 2000 yr 61,000 miles.
