How To Fix A Gelled Up Diesel?

If the cold weather catches you off guard, your diesel-powered rig or light vehicle may be difficult to start or not start at all.

This happens because diesel fuel thickens inside filters and fuel lines, clogging your truck’s fuel system by forming a gel. For a truck owner/operator or anyone trying to travel and gets trapped on a dark and lonely highway in the middle of nowhere, this may be a very costly cost. Depending on the severity and location, emergency call outs to defrost a gelled system can cost anywhere from a few hundred dollars to a few thousand dollars.

Emergency CleanBoost Diesel Rescue De-GelTM was created with one goal in mind: to get you out of an emergency situation and back on the road as quickly as possible. Continue reading.

Drain the water separators/replace fuel filter

If your diesel has gelled, drive it to a warm location (or indoors) to warm up. This allows the wax crystals to return to a liquid state. Jamie Osborne, master diesel mechanic at Fremont Motors Casper, suggests looking for waxy, gel-like particles in the fuel filter. Drain the water separators if necessary, and replace the fuel filter.

Be careful inspecting, wear gloves

When inspecting diesel components, wear gloves since germs can thrive in diesel. It’s also known as diesel bug or diesel algae.

On a related note, this can also cause truck starting issues. “Microbial development in gasoline is generally described as being similar to the appearance of chocolate mousse,” according to Fuel and Friction. It grows in any water present in the fuel/tank.

To avoid this, choose a fuel that is continually moving rather than sitting around collecting water.

How to ungel diesel in an emergency

To ungel a diesel, use a De-Gel product. Gelled diesel is re-liquefied using Power Service Diesel 9-1-1. It can also be used to de-ice frozen gasoline filters.

It does not prevent gelling and should only be used in an emergency, not on a daily basis.

A De-Gel product is not the same as an Anti-Gel product. An Anti-gel will not work if your fuel has already gelled.

Will gelled diesel Ungel?

A variety of things can be put to a gelled tank to aid in the recovery of the fuel to its original state. Opti-Lube Gel Melt and Diesel 911, for example, are made specifically for gelled fuel. Simply fill the tank with one of these and follow the dosing directions. There’s no need to heat or mix the tank. These can take a long time to install, depending on the size and shape of the tank. The treated fuel in the tank may not be able to reach gelled fuel that is not in the tank, such as in fuel lines and filters, which is a significant constraint.

Product Details

In cold temperatures, use to liquefy frozen or gelled diesel gasoline caused by wax production or ice crystals. Quick-Thaw will completely thaw the whole fuel system in roughly 20 minutes if applied according to the guidelines. Excellent for diesel cars operating in colder locations, where wax crystals found in low- and ultra-low sulfur diesel fuels can cause filter blockage.

A bottle of Quick-Thaw should be kept on hand in every diesel truck for emergency cold weather rescue treatment.

How do you get gel out of a diesel tank?

It’s one thing to discover that your fuel contains algae. But getting rid of it and keeping it away is a very different story. If you don’t want a constant headache, you must win this game.

If you have the correct remedy, treating diesel fuel algae is rather straightforward. But what we truly mean by “easy” is “follow these few tips and you’ll have a good probability of resolving the problem.”

Get Rid Of The Water

This is the first stage in any endeavor to remove algae from the gasoline. Water is required for fuel microorganisms to survive and thrive. Drain the water out mechanically if you have more than half an inch of water (you should be measuring it with a tank stick and some water paste). After that, clean up the remaining with some form of water-absorbing chemical treatment. Everything else won’t work as well if you don’t get rid of the water first.

Apply A Biocide, Not Just A Generic “Water Treatment”

I know we just told you to use chemical treatment to clean up the rest of the water. That advice still holds true. However, the treatment isn’t meant to kill the bacteria; rather, it’s meant to improve the environment so that they can’t flourish in the water. No, you’ll need to kill the active microbial contamination in the tank with a specific biocide. Because fuel biocides kill active living organisms in any liquid they are employed in, they are tightly regulated and restricted. That’s a positive thing in this case. Something that will kill the fungus, mold, bacteria, and algae is ideal. Simply scavenging the water will not suffice.

Don’t Undertreat

When we speak with consumers, we advise them to use enough biocide to treat the maximum amount of fuel in the tank they’re considering, not simply the amount of fuel in it at the time.

Assume they have a 12,000 gallon fuel tank with 5,000 gallons of fuel. They will also fill the tank to a maximum of 10,000 gallons. The suggestion would be to add enough biocide to the 5,000 gallon tank to treat 10,000 gallons. That way, when they add gasoline later, they’ll have 10,000 gallons of fuel with just enough biocide to kill everything it comes into touch with.

Because there are usually latent bacteria residing on the tank walls above the gasoline line, this is critical. Using enough biocide to treat the maximum fuel level means that when more fuel is added, the fuel level rises and kills the microorganisms since the fuel contains enough biocide.

Circulate The Fuel To Ensure Best Mixing

This is quite significant. It’s not enough to simply dump biocide on top of current fuel and leave it alone, thinking that the biocide will diffuse down and do its job. The biocide will be injected into the fuel line by industrial bulk fuel users. Why? Because this is the only way to ensure that the biocide is properly mixed in. A biocide won’t work until it comes into actual touch with the organism it’s designed to kill. So, if you want the biocide to work, make sure it’s thoroughly mixed into the fuel. That’s fantastic if you have the technology to inject it into the gasoline line. For many clients, the biocide will be added after the gasoline has been circulated for a length of time. That also works quite nicely. Those are the four most significant suggestions.

Other suggestions include allowing time for the dead germs to settle after they’ve been killed. Also, have spare gasoline filters on hand to filter out any dead bacteria. You’ll have a far higher chance of solving the problem the first time if you follow these easy guidelines.

Can gelled diesel damage injectors?

The gelling, on the other hand, might not be enough to damage an injector. In other words, it gelled, and you didn’t try to run it again until it ungelled. However, if the fuel leading to the injectors has gelled up and the FICM is driving them, the injectors will be starving for fuel. It’s the same as if you were in a low (or no) pressure situation.

What happens when diesel gels up?

Wax particles form in the gasoline, which causes it to gel. The diesel comes to a complete halt. The main problem with this is that the fuel cannot flow correctly through the engine and fuel lines. Not only will the equipment be rendered useless, but the gasoline lines and engine may be destroyed as well.

Can you put too much anti gel in diesel?

Is it possible to use too much anti-gel in diesel? You’ve probably added much too much high-quality diesel fuel additive. Overloading your engine can result in clogged filters, reduced engine performance, and potentially a whole new set of fuel and engine issues. If you’re losing your libido, don’t overdo it.

At what temp does 2 diesel gel?

The cloud point, named after the white haze — or “cloud” — that emerges as paraffin wax crystalizes, is the temperature at which gelling begins. The cloud point of No. 2 diesel fuel is 14 degrees Fahrenheit.

How long does it take for diesel fuel to gel?

  • Gelling: It’s unusual to have a situation where the fuel practically turns to jelly. Gelling happens when the paraffin wax in diesel solidifies due to a drop in temperature, and the fuel’s temperature must be kept below minus 10 degrees F for extended periods of time, such as 48 to 72 hours. When diesel is cold soaked, the paraffin wax in the fuel hardens, giving it a hazy look. At temperatures as high as 32 degrees F, the fuel will begin to cloud, but it will continue to flow. Before the fuel can gel, it must be kept at a very low temperature for an extended period of time. It’s common to hear drivers complain about their fuel gelling up, but this is almost certainly not the issue they’re having. Ice or solidified paraffin wax in the fuel filter is more likely to be the issue. There’s more on that later.
  • Cloud Point: To determine the cloud point of a sample of diesel fuel, which is the temperature at which the naturally present paraffin wax in #2 diesel fuel begins to crystalize, there are prescribed methods. The fuel has a hazy look due to the microscopic particles of suspended hardened wax. Cloud point temperatures for diesel fuel typically vary from -18°F to +20°F, but can reach +40°F depending on a variety of factors connected to the base stock and refining operations. The cloud point of so-called winter diesel fuel (#1 diesel or kerosene) is substantially lower since it contains relatively little paraffin. Fuel distributors will test the product and, if requested, may include the results in tenders and delivery receipts.
  • The temperature at which a liquid loses its flow properties is known as the pour point. The pour point of diesel fuel changes according on the wax content in the fuel, which varies depending on the source of the base stock, the refining process, and the type and quantity of additives added to the fuel during refining or distribution. The difference between the cloud point and the pour point is always there, with the latter often being 2° to 20°F lower than the former. To establish the pour point of a fuel sample, certain tests must be performed. Bulk providers, as previously stated, can supply this information.
  • When diesel fuel is cooled, the cold filter plugging point is a measurement based on a standardized test that indicates the rate at which it will flow through a standardized filtration device in a given amount of time. The CFPP is the point at which the sample fails to pass through the filter in the time allotted.

What temperature does diesel Ungel at?

When the temperature of diesel fuel drops, the paraffin that is normally contained in it begins to harden. The wax in liquid form will solidify at 32 degrees, clouding the fuel tank. It will ultimately start to gel at 10-15 degrees and block the tank and fuel filters.
