Biobor crud

Polished x 3, still had engine failure from clogged fuel line. Emptied tank, found large clear crystals, some size of small fingernail! Dissolved in water, not acetone. Added 30 gallons water to tank, let it rock at dock overnight and then pumped it out. Wiped tank dry, fueled and no more crystals. They were large enough to block the uptake line. Boat had been on lift maybe four years. Last polisher got some smaller crystals, saved them for me, remarked that he had never seen anything like them.
