Fuel tank algae

I had algae bad once. First I had water, filter was rusty looking. Then I had black round silicone looking droplets in filter. It was algae. I used the kill em, it worked real good. I had to change filters, at least 3-4 times. I use a Donelson # p551000 It’s a Cummins filter, with a separator drain on it. I don’t use the drain. They make the same filter w/o the drain, but I don’t know the #. Check them out, the specs looked good to Me. It’s a big filter that still has good flow even when it’s almost full of crud. It should keep any trash out. I haven’t had a plugged filter since I started using them, and the ppm filtering specs are good. I could even get away with not changing the secondary, it seems. But I always do ofcourse. Check for yourself on that filter, In case I’m wrong. Lol.

 

Same filter I use, it’s for a Cummins. The killem starts working quick, filter will plug up, within a day or two, they’ll last a little longer each time, as it cleans up. It comes off in big pieces, like little pieces of dime size slime. Filter catches it good. Since I switched to the 1000 filter, I haven’t had any problems plugging one up, between oil changes,(20 k). I plan on going to 15 k on oil, and using fuel additives, including killem, once a year in the summertime, whether it needs it or not, as a preventative maintenance. That’s my plan anyway, after the OH. But my tanks were nasty, and It did work. Just make sure to have extra filters. I’d change them both just to be safe. But that 1000 catches everything. I put it in place of my original open ended filter,that had a heated spin on plastic bowl, when I priced out the heater. I don’t like those anyway, plastic bowls tend to crack and leak. The Cummins filter was a cheap option. It works great.

 

I have hot water washed them out on the truck. Dried the tanks with a torpedo heater blowing on them. If you can have a primary filter inline with a BF970? or LFF440? that would cut down on filter changes a lot.
I am running a skid steer like that now but have a serviceable wire mesh filter in line. It has no drain and have to pull the engine for fuel tank removal. It was parked for a long time and the fuel cap was off.
Pumped the tank out into waste oil. Pressure washed it and pumped that out. Filled it up with fuel and Killem. We are about 80% fuel used. Cleaned out the screen about 6 or 8 times and one spin on fuel filter.
You should be able to do better than that but I would just mount a primary filter base on the frame. I you can find an A Model Cat primary screen you would not have to buy many filters.

 

Power services bio kleen diesel fuel treatment ( white Bottle green label) works good. One bottle per tank double strength with full fresh fuel and extra filters on hand.

 

You could just buy the base and bolt it right on the frame like Pet and KW used to do. Hook the line from the tanks to it. Then a line from it to your existing filter. The first one is just to be a bird catcher. Something like a LFF8030 might be better but I am not having much luck finding ratings. The 440 and 970 are primary on some of our Cats.
There is somebody around here might be able to shoot you a picture of on of one. It is just a steel canister filter with a screen in it. I believe that 2 stick Pet field find had one one it. Just thought you might have one lying around.

 

No, just get a single head with a bracket, mount it on the frame, between fuel pump, and engine(secondary) fuel filter. My engine usually has a 5206 on the frame, I think it’s the same as a LFF440, and a 5207 on engine. The 5206 is smaller than the 5207, it would plug quick, but before the 5207, I guess because it’s smaller. The heated bowl deal was a common upgrade, it was built with. I guess I have it backwards, in a way. But the big filter still plugs before the smaller secondary. You could run 2 of the 1000s if you wanted. One on the frame, and another on the Truck. Ideally the one on Truck w/o a drain. I don’t like the drains, and never use them, just tighten them up good. I don’t trust them, plastic, might suck air. If You find the same filter equivalent to the 1000, without a drain, let Me know. I had one once, but lost the #.If You but another head, make sure the threads match the filter, you want to use. there’s 2 common threads. I’m pretty sure threads for the 440 are same as 1000
