Re: fuel turning brown after one week in fuel filter
I don't think you have anything to worry about. I think it's the sun hitting the filter and changing the color of the fuel. I hhave the same issue with my v6 crossflow. I ran it 5-6 days ago. Then, I ran it yesterday and the fuel was orangish colored. When I got back from the outing the fuel was blue again. I've seen this now on both of my boats. This boat has all new lines and the tank was removed and cleaned(inboard plastic tank). The other boat has removable tanks(plastic) and all that stuff is clean and clear. It's got to be the uv rays changing the fuel color. If my tanks were not spotless with all new lines, I wouldn't be so confident about it(well, at least my stuff LOL!) But you may want to peek into the tank if it's possible. BUt if you have blue or green gas in the filter and then it turns brown, I would say it must be the sun.
