Case 1070 fuel system

Believe I have fuel leaking into my crank case. A lot, like a
gallon or two over 6ish hours. Is there anything that can be
checked? Does a 1070 have a lift pump? Or is my only
option to rebuild injection pump? Thanks
 
Start by re-sealing the lift pump that's bolted to the injection pump side. The plunger pin has an O ring that could be leaking. Bosch kit DGK 301H has the new hand primer included, DGK 301 is the kit without the primer.
It COULD be the injection pump has an internal leak, but seldom do. Worst case is the main housing is damaged do to erosion internally from the spill port on each plunger barrel.

Got my oil test back today. Oil had been run for 6 to 8 hours. Was 10 % diluted with diesel. Will start with the Busch kit and see what happens. Was happy no water or anti freeze was found in the sample.
