Microbial Growth is the main problem of Fuel and get contaminated. Here, you will read How the fuel get contaminated.

Diesel bug collectively accounts for microbial infestation that cause sludge and muck to accumulate in the tanks that cause blockage in the fuel filters. It’s made up of the bacteria,How the Fuel Tank get Contaminated? Articles yeasts and moulds which the fuel imbibes from the air. The bugs attach themselves to the water droplets in your fuel and drop down to the bottom of the tank where they forage over the fuel above. They differentiate and double in every 20 minutes, throw off waste and succumb, leaving behind sludge and slime that clogs the filters.

Where Does the Water Come From?

Water can enter the fuel in many ways. Many of times, it’s already present in the fuel when you buy it.

The other times, it finds its way inside the fuel through condensation due to temperature fluctuations throughout the day. This can be especially problematic if you tend to tie-up alongside for days, weeks or months at a time.  Diesel fuel is highly hygroscopic, which means that it actually absorbs water from the air.  Bio-diesel which makes up 12% of the most commonly used EN590 fuel absorbs 30 times more water than standard fuel.

Is Water in New Fuel?

Fuels stored in tanks is highly susceptive to get contaminated through the water present in the tank before you poured in the fuel. Don’t forget the hygroscopic nature of fuel means that it is absorbing water from the air as soon as it is produced.

 

It's more than Just Diesel-Bug:

Many engines can run smoothly with small amount of water content in the fuel (except in case of diesel fuel contamination).But, this tends to damage the engine over time, especially in today`s heavy load engines, that use rail fuel injectors. These engines have fine tolerances and rely on fuel as a lubricant, the water molecules reduce the amount of lubrication given by the fuel causing additional wear.  As well as injectors it can damage pumps and cause corrosion.

Possibility of explosion predominantly exists since the engine super-heats any water present, causing combustion.

Removing Water is Common Sense.

It`s clear that water in the fuel is dangerous for the engine and makes it damage prone. So, in case you are aware of any such situation, then you can go for fuel biocide treatments or immediately remove the water.
