I had had the water in fuel since a fill up at a FJ. Could never find any water. Decided the FJ wasn't the problem. Water in fuel was coming on in the dash but not all of the time so finally after a couple of years I installed a new water sensor. no change on the outcome. coming home from the winter in AZ the water in fuel was a steady display so before the last day on the trip I disconnected the water sensor's wire. No change so it is in the wiring for our 05 truck. Just for information we have an in bed fuel tank and fill up at different stations. Inbed was were it started so I drained some fuel more than 2 times and NO water. I have drained the water filter many times and No water has showed. Water in diesel is very easy to see. I will address my problem later this summer.
