Water in fuel drain filter see manual msg. recently appeared on the screen of my '13 F-350. I recently had the fuel filters changed at the dealership(<1000 mi) and typically do not let the fuel level go below 1/4 tank. The day the msg. appeared I fueled the truck in the morning and in the evening coincidently drove through heavy rainfall on the way home from work. The warning appeared about 4 mi. from home and when I arrived I located the DFCM to drain the bowl per manual to discover the sensor lead was disconnected from the filter bowl. I reattached the lead, and drained the filter bowl per manual (2x's) and did not observe any water in container. Is it possible the warning message is a result of the disconnected sensor lead? I am still getting the warning message at this point.
