I have a 2015 Ram 6.7 Cummins, When it rains the "Water in Fuel" light comes on, after It sits for a day inside, or when its done raining / snowing, the light is off. Hard for me to believe that there is actually water in the system as the light is off when its not raining, any ideas what may cause this? Been doing this off and on for about a year.
