Poly diesel fuel tanks have a natural tendency to attract tiny microorganisms, including algae. If you happen to have a fuel storage tank and let it sit for a couple of months without having it filled again, then it will be susceptible for some algae growth. This occurrence can be attributed partially to the very nature of diesel fuel itself.
This is one of the many situations that algae growth can pose serious problem, it can engender engine stalling or clog your fuel filter. It is such a relief to know that there are remedies to help you with in this kind of problem. You may need to reach out to a diesel fuel tank cleaner to do the job.
What Does Algae in Poly Diesel Fuel Tanks Indicate?
Diesel algae, otherwise known also as diesel bacteria, comes in many different types. The most common specie is usually found nesting happily right inside the space between your diesel tank’s diesel fuel and water.
Having water in your diesel tank is not highly recommended or encouraged. However, the vast majority of boaters are constantly finding some good amount of water inside their tank. Water can inevitably find their way into your tank in many different ways. If this happens, it can cause diesel algae to appear, wander and do their thing without you even knowing it. Such organism can multiply exponentially in just a matter of only a few hours.
One surefire indication that your diesel poly fuel tank is certainly infested by diesel algae is that it will start to look misty as opposed to having a bright yellow sun color. If you will let it stand a little more time, sooner you will notice a brown sludge forming on it. Aside from that, there will be slimy and flaky strands floating about as well. This can be usually seen also in the primary filter.
The only time that boater realize that they already have a diesel fuel algae after noticing that their engine is now, more than ever, producing more smoke than before. Other notable indications include dramatic drops in rpm or plain stalling (the underlying reason for which is the fact that their filters have been clogged.)
In some extreme cases, the smell of rotten egg would come emanating from your diesel. This effluvium is surely disgusting to the nose. If you are in doubt, you can purchase bacteria testing kits. Such over-the-counter kits will help you verify if your stored diesel fuel tanks is indeed harboring nasty bacteria.
How Did Algae Found Its Way to Your Diesel?
Poly diesel fuel tanks bacteria can sometimes thrive in between the fragments of air inside your tank and the diesel fuel itself, but the vast majority of which are in between the water layer and the diesel fluid. As a matter of fact, this species of bacteria is also found in the very air we breathe. Perhaps the most logical way there is for them to have access to your tank is via your tank’s vent system.
If aside from diesel your tank also has some water in it, you run the risk of presenting this species of bacteria a nice habitat to thrive in. Eventually, they will form a colony. Beside providing habitat for bacterial growth in your tank, water present in your diesel tank will also work to the disadvantage of your engine in such a way that it reduces lubrication. This is bad because it will accelerate your engine’s wear and tear and runs the risk of it running irregularly. In the long run, this will adversely affect your engine’s overall performance.
