Is there a treatment for the algae that will eliminate it from the fuel system? Biobor JF Biocide or something similar?
To "eliminate" the algae/sludge, once it's there in the system, you aren't going to get rid of it using additives. As you kill it off it's going to go through the fuel lines and plug up your fuel filter.
If it's not that bad of a contamination you can just replace the fuel filter as it plugs up over time, but this is more for "I did an inspection and found a little algae in it" not "my system is contaminated to the point that things are plugging up with sludge"
You can use the biocides to help prevent it from starting, and kill it once it's there, but it still has to be physically removed.
and algae also grows much faster in the presence of moisture, so it's not a bad idea to drop your fuel tank and do a thorough cleaning on the inside of it.
Just a warning if you aren't read up on it, but biodiesel is a pretty good solvent, and will strip algae from the fuel tank walls and system, but bigger chunks will plug up things like the check valves and fuel pickup, and the smaller stuff will quickly plug up the filter, enough to kill the truck going down the highway and strand you if you don't have extra filters and a way to change them.
