I think you'd be the first with the light on. ;)

Sure it is possible that you have water yet again if you filled with bad fuel.Water will be on the bottom of the tank and drawn first.Easiest way to find out is open the drain in the bottom of the filter and drain it off into a container.

I once filled up at a station with a above ground tank in my 6.5 and it took forever to get the water out.Any of those that have had a 6.5 could tell you what a bear that is as there is no drain,you mop it out!

If no slugs of water present you might have to remove the filter again and insure the float is sliding and working correctly.

Good luck
