I got my last 3 tanks of fuel at Flying J in Knoxville. I am guessing this has been spread over the last 4 to 5 weeks. I recently travelled to North Carolina - no problem- came back in a continuous rain fall sometimes very heavy- Water in Fuel light flashing on and off - no spits, no sputters, then I refueled at a local truck stop and am still getting the message on the large and very vivid display of my CC.

Do I just drain the rycor filter again or do I change it and the primary filter -Or is the fuel (ULSD) of such poor cetane that the computer thinks it is watered down?

Is it possible with all the rain/humidity the sensor was getting a false reading?

Anyone else experience this problem? and what was the corrective action?
