Water in Fuel (UPDATE)
Hello all. Looking for some information. Cummins, ISM diesel.
My 'Water in Fuel' light has come on. In the past, when this happened, I simply purged the water separator for about 15-30 seconds and the light would go off. This time, though, it's not doing that. I normally keep my fuel tank topped off to minimize any condensation from forming inside the tank. We are in Florida and have been in the Gulf Coast region for the past five months or so. I last filled the tank in Wildwood and have driven almost 300 miles since with no problems. We left West Palm Beach for Fort Meyers and about half way there the light came on. I stopped and purged the separator but have not been able to extinguish the light/alarm so I'm thinking there's still some moisture in the fuel. I have a 150 gallon tank and figure I've burned about 40 gallons or so. This is our first trip into Florida, and I'm assuming I did not get a bad batch of fuel. The engine runs fine, does not miss and is strong. That said, here's my questions:
With the high humidity of this area, could I have accumulated that much moisture in the tank from condensation?
How long a time is 'normal' to purge the water separator ? Am I not opening the drain long enough?
I'm assuming I did not get a bad batch of fuel as I think it would have surfaced well before 300 miles. Is this a fair assumption?
What else should I look for/do? The fuel filters were all changed in March of this year. I have extra filters on board and am currently parked at a campground so it's not yet an emergency situation.
Thanks for any advice and/or suggestions.....Dennis
