Hi forum. I've yet to get the "Water-In-Fuel" light. I do occasionally open the valve on fuel filter housing to let accumulated water out and I can recall on a few occasions seeing water in the container used, but I've never had the WIF light go on and I'm wondering how often it happens to others ? The manual says 30-40 kilohms causes the light to come on so easy enough to test sensor and trigger a false positive.
