Last tech had double stacked (old and new) center washers). Just replaced my filters. I think my AH filter is plugged but I haven't checked it yet?

I hope the tank cleans itself out. Last AH filter, if plugged, didn't last 30 hours.
It did sit for a bit before I got it 4 years ago.
I think there is a tank drain port (under the undercoat) on the roadside but I hope to not have to mess with it.

How does one determine if it's bio cleaning the tank or 4" of sludge/asphaultines or something in between.

Jeff, Biodiesel is a great cleaner. Most of the problems I hear about are when first starting with bio it tends to clean the whole system of any crud. Guess where it ends up? In your filter. The outher problem you may have is if it sat for a while it may have Microbial contamination. You should regularly dose your fuel tank to prevent it. This shows up as a black specks or even a black slime in the filter. Biofuel increases this problem. You might like this link for more info.

I looked this up in my Cummins manual that came with my Coach when the bio came about, and it states it will operate with up to B-20 fuel.........so, it looks like Cummins was looking into the future a long time ago as mine is a 2000 ISC 8.3
