How long or where are you storing your tractor that its growing stuff that bad in the fuel tank ? Curious if there is anything simple I can do to prevent this other than treatment

My understanding is algae,fungus,ETC in diesel fuel needs water to survive. Getting rid of water plus bio-cide application goes a long way to get rid of the problem

I run Power Services products with my diesels. I use the grey bottle in my 3 ea. 55 gallon drums in the designated "fuel trailer" when I go to town to fill up. Before filling a drum, I look down at the remaining fluid in the tank (sitting below the pump pickup tube) and it's red and crystal clear, no algae, no water, nothing but off road diesel. Also use a filter after the pump (12v TSC cheapest). Zero problems.

Part of the problem with BX tractors is the small filters that plug up easy. There are several threads on how to add a larger, better filter.

OK, thanks for the replies!

This was one of the questions I already knew the answer to, but was hoping for a 'miracle'. Time to biocide and get the fuel tank out, then keep up with treatments.

Forget about removing the tank!
It is not necessary, unless you know that you have something that is physically plugging the tank outlet, like rust or other debris.
I had a boat (was 19 years old when I sold it) with 900 gallons of diesel storage.
As I am sure you can understand, I would never have considered removing the 3 boat tanks (would have needed to cut the boat apart).
I had a fuel polishing system, and occasionally cycled the fuel through a separate set of filters.

Drain your tank, and replace with fresh fuel, adding Biobor JF to the fresh fuel.
Biobor JF will kill whatever might be growing in your tractor tank.

I had to have the tank on the 30 YO JD855 flushed and cleaned. It worked fine after that.

I use the Power Service Biocide and Clear Diesel additives. I do not listen to the "experts" as some of them are heavy users and go through a lot of fuel. I might put on 100 hours a year, and fuel can sit for a long time both in my 50 gal storage tank or the tractor fuel tank. I see it as cheap insurance. In the winter, I add the anti-gel as well. BTW, I have my storage tank in the garage on HF dollies. Keeping it in the garage reduces the temperature swings that produce condensation.

I didn't know any product would kill or dilute the algae after it was present in the system. Pretty sure you will have to suck it out as best you can. A small hose shop vac could be used to get it out. If the opening is large enough to get your hand and arm in you can mop the empty tank out after vacuuming. Alternately you can attach a rag to a stick and mop it.

I still think adding a filter inline on the hose coming out of the tank is the best early warning system. I have done it to both of my tractors and my diesel generator. When I cleaned the rust out of my backhoe fuel system the add on filter clogged a couple of times shortly after but hasn't clogged again in a couple of years.

Lots of chemical solutions to prevent it from forming.

Unless you have a spark and static proof shop vac you should never vacuum highly flammable materials with one. The motor produces sparks which can ignite the fumes and/or dust or you can get static electricity which will ignite the fumes and/or dust.

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