Help! invasion of the black crud

[Lonestar10]

you can super shock the algae if its that and not asphaultine and just carry a few extra fuel filters onboard. my truck came out of minneyota so it ran a lot of biodiesel which i tend to like truck seems to run better when i find a B20 blend pump. but it had algae so far Ive ran 2 harsh treatments of bio-cide and have only killed 3 fuel filters in 2 months.



Ive never pulled tanks but i would think a 140gal aluminum tank would probably be in the 100-150lb range.
