I had the fuel system from hell a few months ago. The tank was heavily contaminated, with around two GALLONS of algae in it.
I tried all kinds of stuff, including bleach, but the only product that killed AND cleaned effectively was power service Diesel Kleen. I even tried Methyl Ethyl Ketone, very nasty stuff, a strong cleaner, that eats most plastics and crumbles rubber, but it wouldn't budge the algae.
Unfortunately, I used several biocides at first, which killed it, and dissolved it to the point it made it past two filters and into the IP and injectors. The dissolved algae, sitting overnight in the IP and injectors, locked them up as if I had filled them with superglue. The IP was toast. I couldn't get the needles out of the injectors, even after 8 hours of ultrasonic bath in MEK. After 4 hrs of ultrasonic in pure DieselKleen, I got the needles out using a bench vice, vicegrips, and around 50 pounds of pulling force. Had to buy new IP, injectors and replace most of the fuel system.
here's the inside of the fuel tank, the black is algae
here's the fuel sender/pickup plastic piece, with red/brown algae inside
here's the same piece after an ultrasonic bath of 50% diesel and 50% Diesel Kleen
gooooood luck,
It really wasn't any fun.
