How To Remove Water From Diesel?

It’s critical to respond quickly if you discover water in your diesel fuel tank. Water and fuel aren’t buddies, and they shouldn’t mix because horrible things can happen. What’s the best way to remove water out of a diesel fuel tank? This article has taken the time to answer this question!

There are several methods for removing water from a diesel fuel tank. These two strategies, however, are the most effective:

  • The first method is to use a hand pump to siphon away the water-contaminated fuel using a siphon kit. Ensure that the line is long enough to reach the tank’s bottom.
  • To help dilute the water fuel mixture, you can add a fuel additive with a methanol base. This procedure should only be utilized if the diesel fuel tank contains a small amount of water.

Remove the fuel filter while using either approach to assist drain any surplus tainted diesel fuel.

For a variety of causes, water can enter a diesel fuel tank. Water must be evacuated from the diesel fuel tank in some fashion, regardless of how it got in there. We’ll look at how to get water out of your diesel fuel tank in more detail in this article. We’ll also talk about the dangers of water getting into fuel tanks, so keep reading!

Can you separate water from diesel?

Contamination of water is one of the biggest adversaries of diesel-powered machinery. All fuels have some water in suspension, but diesel fuel is less refined than gasoline and can carry a lot more. This water can cause serious issues with the equipment’s water separators. It can also result in the fuel injector tips exploding, requiring costly repairs. In fact, slugs of water in the fuel can induce rapid cooling in the engine, which can limit its life.

Water in solution and free water can both be found in diesel fuel. “According to David Harvey, Citgo’s manager of product and technology, “diesel fuel can contain modest levels of water that may be dissolved in the fuel, thus the term ‘water in solution.'” “Parts per million are used to describe these extremely low water concentrations (ppm). A diesel fuel may contain dissolved water for a variety of reasons. Condensation of water in a gasoline tank, components in diesel fuel that aid in the retention of water in solution, and fuel temperature are among them.”

However, only modest amounts of water can remain in solution as water. “Due to the major differences in the chemical characteristics of diesel and water, water does not generally exist in high concentrations in a regular diesel fuel,” adds Harvey. “The two liquids will usually split, with water evaporating from the diesel fuel and pooling at the tank’s bottom.”

The water that isn’t dissolved in the diesel fuel is referred to as ‘free water.’ “Water suspended in diesel as a result of agitation or water phase split from the diesel fuel” are examples, according to Harvey. “The most common cause of free water in diesel fuel is improper storage tank maintenance. The nature of the fuel or additives that help dissolve the water into a solution are the most prevalent causes of dissolved water.”

The quantity of energy accessible in a burning fuel is reduced by water in suspension, resulting in lower horsepower production. Water in fuel tanks, pipes, injectors, filters, and other parts of the vehicle will freeze faster than the fuel. Most fuels freeze at temperatures below -20°F.

What happens when water gets in diesel fuel?

Anyone who works with diesel fuel, from builders and landscapers to delivery companies and auto dealerships, is aware that water issues are a constant concern. Whether you preserve it for a long time or not, this is the situation. You’re in big trouble if water gets into your diesel fuel system. Contamination of water wreaks havoc on this powerplant. Let’s have a look at the primary reasons why water and diesel don’t mix.

We all know that water freezes. However, did you know that it freezes faster than gasoline? Here’s an example of a comparison:

When water gets into your gasoline, it freezes, resulting in issues such as power loss, clogged filters, corrosion of fuel parts, and injector damage. That’s why, if there’s water, you’ll notice greater problems in the winter.

Gas is more refined than diesel, so while having water in your gas tank is bad, it’s even worse with diesel because it holds on to more water. In addition to the issues listed above, your engine’s lifespan may be shortened, and repairs may be costly. If you need to repair a fuel injector because it exploded, for example, it will be expensive.

Diesel and water, like oil and water, do not mix; instead, they separate. As a result, if you have water in your tank, it will settle to the bottom. Your tank will corrode and algae will bloom as a result of that water. Rust floats about in your gasoline filters, obstructing and ruining them. Bacteria create waste and continue to eat away at the engine and its components.

It’s not uncommon for condensation to form and then dissipate as the temperature outside changes. That isn’t the issue. It occurs when there is an excessive concentration of water. When this happens, problems like engine power loss arise. Examine the fuel; if it’s clear, that’s a good sign. There’s a problem if it isn’t, for example, if it’s cloudy. That is why routine maintenance is critical.

There’s a good likelihood you have water difficulties if you notice your vehicle or equipment isn’t performing well, especially if the idling is inconsistent. If the engine cuts off during acceleration, there are two alternative ways to tell.

Microbes multiply quickly in your tank, produce waste, and are difficult to eradicate. This is especially true if the underlying water problem isn’t addressed, as bacteria and fungus require water to survive.

A gasoline additive might work if there isn’t much water in the tank. Otherwise, the tank will have to be drained. If you have an above-ground tank, this is the best and most complete option. After that, clean the inside and remove any rust or corrosion. If you haven’t done this in a long time, your tank may need to be fixed or replaced. Ricochet Fuel can assist you.

Does Diesel 911 Remove water?

Diesel 911 is the product that diesel-engine operators call when they have a fuel emergency, as the name implies. Water is the most common problem in diesel fuel, and it can lead to microbiological growths, rust or accelerated corrosion, a reduction in the lubricating qualities of the fuel, injector nozzle damage, and, in the winter, fuel-filter ice, among other things.

Diesel 911 Features:

  • Diesel with a very low sulfur content (ULSD) Sulfur content in Compliant is less than 15 parts per million (ppm).
  • No tow truck is required to reliquefy gelled petroleum in minutes. Water is removed from the fuel system, extending the life of fuel filters, injection pumps, and injectors.
  • Fuel injectors and pumps are protected from accelerated wear from Low and Ultra Low Sulfur Diesel (ULSD) fuels because it contains Slickdiesel for maximum fuel lubrication.
  • Contains the non-harmful alcohols that diesel engine manufacturers recommend for removing water from diesel fuel systems.
  • Does not drop the flash point of No. 2 diesel fuel below the ASTM minimum requirement when used as indicated.

Is diesel soluble in water?

Water has a fairly low solubility limit in diesel fuel (100 ppm at 40°C), although various additions raise it. Diesel fuel may contain up to a few dozen parts per million (ppm) of water, which is common at the time of manufacture.

Can you use too much diesel extreme?

It’s possible to have too much of a good thing. It’s easy to overdo it with a high-quality diesel fuel additive. Overdosing can result in a slew of new fuel and engine problems, ranging from clogged filters to decreased engine performance and efficiency. Don’t over-treat if you’re losing lubricity.

How do you fix cloudy diesel?

Your fuel should be clean and bright, whether it’s road diesel or red diesel. You should be able to see through it like water, regardless of whether it is yellow or red. If you’ve taken a sample of your gasoline and are wondering why it’s hazy, or even worse, why it’s lost all transparency and is now a milky consistency, you may have a water contamination problem. This article will explain what causes hazy and milky diesel fuel and how to remedy it, as well as how to avoid it from happening again.

So, what causes diesel fuel to look cloudy?

It’s crucial to know the difference between free, suspended, and emulsified fuel to understand why your fuel is milky or foggy.

As you may be aware, fuel can be polluted with water due to rain, humidity, and the natural water content in today’s biodiesel. You may not be aware that water contamination in diesel fuel can take two forms: free versus suspended and emulsified water. So, what’s the distinction?

  • Free water – As the name implies, free water is present in the tank but exists independently of the fuel. It settles to the bottom of the tank, forming a water layer beneath the fuel. The diesel bug thrives here, putting your equipment, vehicles, and engines at risk.
  • Suspended water – Your foggy diesel fuel is now the result of this form of water pollution. Suspended water is water that is bound to the fuel molecules and is mixed in with the fuel, giving it a murky appearance. When the diesel tank becomes too full to hold any more water, it begins to leak free water to the bottom of the tank.
  • Emulsified water – As the fuel passes through pumps and filters, it is subjected to pressure variations, agitation, and strong cavitation, which causes the water content to totally emulsify, turning it from hazy to milky diesel fuel. There is essentially no separation between the fuel molecules and the water content at this point.

If you’ve taken a foggy diesel fuel sample and found it, we recommend taking a sample from the bottom of the tank as well, as you’re likely to have a problem with free water. Both types of water pollution must be addressed immediately, as they can have disastrous consequences such as diesel bug/nasty sludge growth, clogged filters, damaged pumps, engine failure, and fuel system corrosion.

How to fix cloudy diesel fuel?

If you notice milky or hazy diesel fuel, you must act quickly to avoid costly repairs and downtime. But how do you go about doing it?

1. Filters for fuel tanks

Standard fuel tank filters that remove water before it is distributed into your vehicle or equipment are an excellent solution for removing free water, but they do not remove emulsified water. While they are a cost-effective method for dealing with one aspect of fuel pollution, they cannot remove the water that causes your diesel to seem hazy. Furthermore, ordinary gasoline tank filters only address the issue after the fuel has been delivered. They do not alleviate the difficulties associated with diesel bug growth and sludge formation since they do not aim to eliminate the water content while it is resting in the tank.

2. Polishing of the fuel

Fuel polishing is a method of removing cloudiness from diesel fuel. This service is normally performed by a professional on a regular basis and entails withdrawing the fuel from the tank and passing it through highly effective filters that eliminate pollution to EN590 diesel fuel quality standards. Both the free and emulsified water content in the fuel will be reduced to the required 200ppm after fuel polishing. But what happens to your tank’s water content between fuel polishing services?

3. Water absorber for the Aquafighter fuel tank

While alternative diesel tank water absorbers are available, Aquafighter is the only fuel tank water absorber that also eliminates the suspended and emulsified water that creates hazy and milky gasoline.

The beauty of this solution is that all you have to do is drop Aquafighter into a storage tank, genset belly tank, or vehicle fuel tank through the biggest aperture, and the diesel tank water absorber reduces water content levels to less than 75ppm. As a result, the EN590 diesel fuel specifications of 200ppm are met and exceeded. The Aquafighter fuel tank water absorber works in this way to maintain your fuel tank free of water and foggy fuel at all times, without the need to remove the fuel first.

Now that you know what milky or foggy diesel fuel is, you’ll understand why it’s so important and how to address this water pollution side effect before it becomes a major problem.

How do you remove moisture from a cylinder?

Remove the spark plugs, detach the fuel injectors, and start the engine with the key. You should be able to clear all of the water out of the spark plug holes with just a few revolutions. Replace the oil and filters after that. Make a point of changing the oil every 500 miles or so, just to be safe.

How do I get water out of my engine block?

When it comes to flushing the cooling system, the exact procedure will vary from vehicle to vehicle, therefore consulting your car handbook is vital. A mechanic will be able to tell you if it’s really essential, so make sure you ask before you do anything.

Does water sink in diesel?

Check to see if the diesel fuel contains any water. Using a hand-operated bilge pump, extract a small amount of the suspicious fuel. Allow the fuel to sit in a dark room for 24 hours in a clear, clean glass container. Because diesel is lighter than water, any water in the fuel will sink to the bottom of the jar. Look for a thin black line separating the water from the fuel. If there is, microbes have begun to grow, necessitating the addition of a biocide.

What color is water in diesel fuel?

It was water if you got a clear liquid from your primary fuel filter/water separator. The hue of diesel is golden. If you use a clear plastic bowl gasoline filter rather than a metal one, this is obvious to see. Any layering visible in the transparent bowl is an indication of a problem.
