    The pump is internally lubricated and cooled by fuel pressure. I guess if the input seal let go, it could pour fuel right into the crankcase from the aux drive. If you put dye in the fuel, you should be able to remove the aux drive pulley cover and look inside with a UV light and see if there are traces of dye in there.
