Truck was ticking plus it was oil change time so I pulled the fuel filter to find it a complete slime ball. I read a little about this but what are you guys doing to fix the problem? Are you just adding the Bio additive and driving? Did you drop the tank and clean? How hard is it to drop the tank. I also understand it is a bactiera since there is no sunshine in my fuel tank.

Thanks for the help.

 

I would say you have to back a little , you need to find out what it is 1st , then go from there .
At least by what you written here , there is not enough info to be sure of what your issue is , how long has the truck sat , if it has since the last fuel ?
Then where did it come from , do you know if there are any fuel blends [ bio diesel ] or what ever ?
How much in the tank ?

 

Your truck has AIDS.

 

I drive the truck everyday. I change the fuel filter with every oil change. The filter has been getting worse as time goes. I fill up once a week. Work pays for fuel (2000 gal. above ground tank) I've never fueled up anywhere else so I can not blame it on a gas station. No fuel blends I'm in south Arkansas.

Thanks for the help.

 

Still finding out what it is for sure , being that its an above ground tank increases the likely hood of algae [ for 2 main reasons , condensation/water and heat , both are as a result of tanks that sit outside ] .
Not being a station and get fuel from work may be a problem , because its common for stations to pay for repairs , you need to talk to some one there to see about this , because this can shorten the life of the fuel system , or kill it .
They need to have a fuel polishing system , especially with above ground tanks .
So get some good testing done , so that you have positive info for both of you to work off of .

 

I will have to do some digging on the issue. We have 5 or 6 trucks some tractors/backhoes/forklifts that are pulling off this tank also.

 

Algaecide will kill the algae and continued use will keep it from growing but your filter will still have to deal with their dead bodies.
Either you drop the tank and flush it out or keep on changing fuel filters.
Dropping the tank is easy as long as it's almost empty.

 

Get a high volume filter for the fuel pump on the 2000 gal tank and use algaecide every month or 2(more in summer). Also make sure they drain the water off the bottom of the 2000 gal tank every few months too. I would not drop the truck tank unless you knew you were having fuel problems. In most cases a few filter changes will do the job but you must stop the algae at the source.

 

You can 'polish' existing fuel in storage with a pump and good quality filter.
Using water blocking filters on the truck helps since they clog when they soak up water, letting you know something is wrong.
Cleaning the tank out is the best way to save money on filters.

 

If it is a work tank I would take your gross filter in and have a mechanic pull the filters of the heavy equipment that drink from that fuel tank and take them to your boss. Let him know there is a problem so he can fix it before something on your truck or the equipment breaks.

 

Is there an algaecide for my truck tank? Where do you get it?

 

Yes contact any fuel distributor or check out a major truck stop. Usually comes in a Gallon container and cost about 60 bucks. However I repeat that if you don't kill the algae at the source you will continue to have trouble forever.

The Members here are giving you some good advice on this.

FWIW,.....I had the EXACT same problem as you, but it happened on my 35'
Newmar Dutch Star Motorhome with an 8.3 Cummins Engine. It developed in the 100 gallon fuel tank over the winter. Here is a link to the thread I started on my problem and the input I got from my fellow Members here:

https://www.dieseltruckresource.com/....php?p=2413726

The fuel tank on my motorhome is VERY hard to get to, so I decided to try the biocide as you mentioned. I used a brand made by "Racor" called "Diesel Biocide" and got it from Scheid Diesel (1-800-669-1593 or 1-800-669-1934).
The stuff is VERY concentrated and I started with a 1/2 ounce to 20 gallons, about what was left in the tank. I ran that through the engine etc, to
completely drain the tank. I then added about 3 to 4 ounces of the "Racor Diesel Biocide" again, but filled the entire tank with 100 gallons of diesel fuel.
After about 250-300 miles, I changed my fuel filters again. I have a plastic "viewing bowl" on the first fuel filter and that bowl was almost free of that "black slime ball" stuff. After those filter chages, I ran another 250 miles and changed my filters again. But this time, I cut my filters open to check them internally to make sure the algae was all gone. I am happy to report, I saw NO MORE algae in either of the pleats on the two filters!

Granted, I may not have had as much algae as I originally thought, but IMHO,
that "Racor Biocide" worked GREAT!

Hope this has helped you some Sir!
