Is it possible for a bad fuel pump to allow fuel into the oil? I changed my oil recently, and noticed there was a good amount of fuel mixed in with it. Someone suggested that maybe the diaphragm in the fuel pump is torn, and allowing fuel to get into the oil. I'm going to replace the pump regardless, because I noticed some fuel seeping out around the pump; but I would like to know if this has anything to do with the fuel-in-oil problem. Thanks, Thomas.
