Well got the filter changed, it looked like the fuel gelled, waxy substance on the filter and some in the fuel I drained out. I had treated the tank before the bio with Fuel Power so I figured when I filled up, just before the cold front, it would be alright. Maybe it's more than just 20% bio.
I don't know of anything else that would look like what I saw.
Restriction gauge is back to 5 in Hg. I added some fuel treatment but still getting some erratic pressure just not as much. FPPF makes a treatment specifically for B20, I may get some of that on the way. Changing stock filter too maybe.

I spoke to Bob about Bio diesel and the Dahl filters and he wasn't very savvy in the area but from my experience you'll want to change the stock filter after awhile but 10 miles I don't think it'd shake the crud in the lines that fast but who knows.
You could change both just to be on the safe side.
Bob was very interested last night with what I found out as he admitted to not being all that knowledgeable about the Bio. He's been very helpful with ideas. This morning he was kind of puzzled about the substance found and possible gelling.
