Diesel Biocide seems to be good, but what about this...

[Reb954]

Safety is always important. Diesel is a bit harder light with a spark or static than some otherr products.

That is true but when it is vacuumed, some of it becomes an airborn mist which makes it more flammable and explosive.

Yeah when I did mine I made a vacuum reservoir unit so the actual vacuum cleaner had some separation from the process.

I didn't know any product would kill or dilute the algae after it was present in the system.

Here you go now you do think of it as a fungicide for fuel. I bought a 300 gallon contaminated tank a long time ago. Drained, shocked it , and fillled it and per Bio Bor's recommendations and keep it it treated never had a problem

You'll want to be sure you're not introducing water to the tank from storage or transportation. Drain that old fuel through a Mr Funnel and set aside for non-vehicle use. (machinery cleaner, fire starter, etc.) then start over.

I use Mr Funnel NF3NCs, one each for gas and diesel. a bit messy to use, but amazingly effective at its job. Every time fuel goes from one container to another it goes through one of these. btw, I strongly second BioBor as an effective preventative.

I may switch to this next time. I just used the last of my Killem Biocide. I've been adding 1 ounce of biocide and 8 ounces of Stanadyne Lubricity formula per 55 gallons at every fill so maybe the Biobor can do both for the price I was paying for biocide alone.

Just had my drums filled this week. The bottle of Killem lasted me 3 years so it's not a bad deal at $29.99 but the Lubricity additive was costing me another $10 per fill.

OK, lots of good advice. Thanks for the input!

I did get some of the biocide and put it in my tank 5 days ago. Been too busy at work to do anything else, but weather permitting I'm going to drain the tank this weekend and change fuel filters. I'll eyeball it and see if I can manually remove anything, although the opening size isn't going to allow much. Then replace fuel with new diesel + biocide from now on. If all else fails, I can always pull the tank.

Also going to look for those larger filter threads.
