Been running B100 for quite a while now. Changed fuel filter the other day and there was a rust colored film in the fuel bowl, and on the filter. I did change the fuel filter after the first couple of tanks and had nothing like this. Now I am just curious iif this is the Petroleum sludge I have heard about or if this is something else? Any ideas?
you are probably getting some of the junk from your tank loose now and that is what it is. I had that for a bit too. I run wvo in my front tank and until I dropped the tank and cleaned it out I got that junk too. I run diesel in the rear tank to start and stop on so I don't have probs starting.
