So, I've been running about a B20 mix, topping tank off with B99, for about two years. I hadn't changed my stock fuel filter in about 5000 miles and the 2mic in about 10,000 miles. Anyway, pulled the stock filter and found this sludge/goop snot looking whitish gunk in the bottom of the fuel canister. I poured some Seafoam in, dissolved it, and drained the canister. Everything is cool and fuel pressure is at a steady 22 psi. Anyone have any idea what it was? Something left over from the bio?
