How to remove algae from a diesel fuel tank 

this video came at the PERFECT time. I just found algae in the tank of my M35A2. Thanks for another great vid!

Glad I found this video bc I changed my fuel/water separator filters on my 379 Pet today and found it. I’ll be buying that stuff tomorrow to try and get rid of this mess. By the way my truck sat for 4 months due to me having major surgery so I think that’s how it formed.

I used the Clear Diesel and it clogged 4 straight filters in my motorhome. This stuff works ! Just take extra filters if your going on a trip after adding it to old fuel

Thanks for getting back to me, I will clean it out and let you know what I find. Thanks again your videos are very informative.

Very interesting video I never new about the Algae in your fuel tank and how to treat it!!!! AWSOME INFORMATION

Just found this, I'm having the same problem. Thank you for this timely video. Thank you

I pressure washed what I could, dried it with compressed air, treated it like you did then drove it for a few days and changed the fuel filters. I filter used motor oil and transmission fluid from every car I scrap and cut it with gasoline from the cars. Then the other 50% is diesel fuel. Haven't seen any more growth since the cleaning.

Thanks for the help very helpful

What your using or killem biocide is what's always worked for me, and has done great job at keeping my fuel in all my mv trucks, the 1000's of gallons of fuel I keep stock plie, in my military generator and other things. It's well worth the money to dump that in, vs replacing filters, fuel, parts. Glad to see your using the same thing and about everyone I know uses it and no issues.

I came for a look at what the product can do, but it looks like you havent used it yet. You give good info, but do you have the after video?

Another good video would be changing the fuel filters and how to re prime the fuel lines

Could you post exactly what you bought ? It looks like 3 different bottles. THANKS

your truck has COVID... keep it 6 ft away from other vehicles.

thank you so much...i have been dealing with this for 1 and a half years on my John deere tractor...and 125 gallon fuel storage tank...been treating both but still problems...i believe the bio stuff kills it but it is still there...they don't understand this...i believe from my experience and treating /dealing with this that maybe this bio stuff will kill it but it does not dissolve it where it is not a problem...thanks for you info, i am still dealing with it and researching it.....

Lol very timely I have this problem

Paint strippers won't do much, but ACETONE will dissolve diesel microbials in no time. I had a tank more filthy than yours that would clog filters in minutes and since I couldn't dismount or cut open the tank to mechanically clean it, I poured a few gallons of Acetone in and towed the vehicle around to slosh it good for an hour or so, then siphoned the liquid out and it came very clean. NOT paint thinner, but pure acetone.

I have a little diesel air heater - wondering what the hell those flakes of green are - looking like algae. A little water in the bottom. Guess I'll tear it down and blow it out ever so often. I was thinking just to vacuum out the tank and be done cause (compared to yours) it's not bad at all. Dunno yet!

Fuel docter austrailian version does petrol and desiel.

I just found out I had some in my truck

Hey there, do you have an email for business inquiries?

Just put thinner. To clean the ranl

Any idea what black looking chips are that resting at the bottom of my fuel tanks? Some one told me that it also was some sort of algae.

Can I mix the bio kleen shock treatment with the kleen diesel product at the same time?

Thank you for your videos. I'm new to diesels. I'm new to M35A2's. I have never heard of algae in fuel tanks/fuel lines. Please, please, please, show how to DROP a fuel tank. It looks like there are about 6 or 7 different connectors on the fuel tank. I'm clueless on how to remove them. The fuel pump looks easy enough. And the steel straps appear easy enough. But, on my 1971 M35 there are a number of separate connectors on top of the tank. I don't know what they are, what they are for, or how to disconnect them. Any help is appreciated. Thanks again.

I have used it in my m1009 and it seemed to work I went a long time without changing filters

I'm running a 95 powerstroke, sat for 2 years, died while driving, found fuel filter contaminated with algae. So I'm treating the front 20 gal tanks with 1oz of bio kleen. I would rather spend 30 bucks on the chemical than all day pulling my truck apart to get to the fuel tank. I am curious, how did it turn out for you? obviously im going to have a contaminated fuel system... the stuff wont just disappear from the chemical.... does it 'melt' away and become easier to combust? or do you have to actually kill it all then clean tanks? I am hoping a simple tank treatment will help me. thanks in advance

If I just wanted to cycle the fuel through the fuel system, can I use a 5 gallon bucket and cut a hole in the lid to fit the fuel pump? then put 3 gallons in the bucket and fire up the engine? Or will the diesel melt the plastic?

Has anyone ever used "AJX" it's a algae treatment the company is based out of Florida

Had this problem in our little 5.5ton excavator, since it only runs a few hours a year(barely) and used to filled it with regular diesel thinking it was all good, but it got clogged up seriously. Try to use Blanche diesel, Without any RME in it. RME will result in algae-infestation... The tank was the major "wormhole". But E85 did an amazing work on this, but it took almost a week to clean it out because of the different angels and hard to get to spots, and because you got to leave it to do its work. We tried everything,(every liquid known to man) gas and ethanol included, but E85 worked like a charm. Try it, i can guarantee you wont be let down. This worked wonders for the tank, but i wonder how to inject this concoction into the fuel-system and to let it sit for a few hours before flushing it all out. Any ideas anyone??

It's worth 4-5 rolls of paper towels to get everything out

How often should I use it?

Diesel fuel isn’t gasoline
