Ran a second 5 gal out to my second jug. Still about 5 gal remained in the tank. The fuel in the jugs looked fine. I imagine that the crud was filtered out by the in-line filter in the fuel system. Checked the sight gage and the crud was thicker than ever! Put the two jugs of gas back into the tank through my super fuel filter funnel. I figure I'll have to run 100% of the fuel out of the tank and rinse a couple times with clean fuel to get the crud out. To do that I had to stop at Home Depot and buy another 5 gal jug and a 2.5 gal jug to make sure I had enough jug volume to hold all the fuel. Tomorrow, I'll be emptying and filtering fuel.
