Algae in fuel

What are you putting in it for additives - there a lot of different types?

Very seldom will any vehicle get algae in the tanks, have the shop prove you have algae. Algae requires water and sun to grow, 99% of the time algae will be pumped in, and that can't happen with filters in line. Your first symptom will be continued clogged filters. and low fuel pressure shut downs.

Black fuel is not algae. take a sample and have it analyzed prior to paying big bucks chasing a problem that you don't have. BTDT over the past 4 years.
Algae develops a slime that will not pass filters. If you do not have filter problems, 999 times out of a 1000 you don't have algae problems.

You need some algae biocide fuel additive. Also, once you get this cleared up, always store your fuel tank full of fuel, so that condensation can't form nightly in your fuel tank. It's that condensation that provides water that provides what algae needs to bloom and grow in your fuel.

It didn't affect performance at all but the filter is loaded . Thanks

Loaded with what? how did it get there?

There are additives specific for algae and should be used in vehicles that sit a lot and don't use up the fuel for many months. And it doesn't need sunlight to form in this case. The algae forms when there is water in the tank so if you have a drain on the bottom of the tank that would help. But most tanks don't have a drain so an additive is needed. Some auto parts stores and most commercial truck dealers should have some.

This is a good theory but in practical application doesn't make a hill of beans. there is not enough air displacement during the night day cycle to contain enough humidity to develop water in the tank.

This applies more to huge tanks at the refineries where huge quantities of air / humidity can be drawn in to the tank.

I have been putting in the Honey colored additive you get by the gallon at the truck stops . Always buy from name brand big truck stops ' I am wondering if any algaeside and a couple of filter changes would help with my situation . Don't want the crud to make into my injectors and pump .

I have decided to have them change the filters now and check the filters in a few months . I will treat the fuel and keep an eye on it and rely on both my filters to do their job. There is an additive called Diesel Tech for boats/algae problems. I have never lost power , chugged or had the check engine light come on . Thanks to all for your responses , the guy at the Cummins center agreed with me .

Now you can tell the greenies that you have joined them in going green movement!!!!
LMAO ;)

Takes only water and time. Algae in caves don't have sunlamps. Filled-to-the-brim tanks condense zero water in humid climes. Live with a diesel and 100% condensing humidity for awhile and attend the Graduate School of Hard Knocks. My Racor fuel water separators tell me I have water, I change vendors FAST! I have a giant Racor with S element (1-micron) used with an electric pump to vacuum water out of storage tanks. Each diesel also has the Racor S grade filter.
