How do you dispose of dirty fuel?
Yesterday when I changed my fuel filters in my 2004 E450 6.0, I drained over a gallon of fuel from the lower filter housing before I pulled the cap off. Then, left the pan under the housing when the cap came off and collected a bit more fuel. There is a little bit of water and junk in the fuel from the filter housing, plus maybe a little bit of residual dirt in the pan I used. What is the best way to dispose of the fuel? Do you screen out the junk and recycle it to the fuel tank?
