I had "water in fuel" alarms go off on my Cummins QSB 390's this weekend but found no water in either Racor unit. Also one engine alarm cleared itself but came back on after a 30 minute run. I only have 80 hours on the engines since a full filter change and annual service. The boat did sit for 3 weeks this time with 1/2 tanks but I'd be very surprised if that contributed to my alarms. Also I ran 90 miles on the fuel in the tanks with no issue until I went to the boat this past weekend.
Anyone have any ideas before I schedule a service call? :huh:
