What You'll Learn
Dilute with kerosene or black diesel
Diluting the red dye in your fuel tank with kerosene or black diesel is a strategy known as "bleaching".
One method is to mix the red diesel with kerosene. Another method is to stain it with black diesel, which is used motor oil that has been filtered and cut with kerosene.
It is important to note that even after diluting the red dye, you may still fail an inspection if a test strip detects the presence of red dye in your fuel tank. These test strips are highly sensitive and can detect even the smallest amount of red dye.
One way to naturally "bleach" the red dye out of your fuel is to leave it out in the sun for several weeks. The UV rays will destroy the dye, turning it into clear diesel. However, it is important to be cautious when handling fuel and to avoid exposing your skin or eyes to the UV light or the fuel itself.

Leave the fuel tank in the sun
Leaving your fuel tank in the sun is a method that has proven successful for some people trying to remove red dye from their fuel. This method involves leaving the fuel in a clear glass jar or bottle in direct sunlight for a few weeks or even months. The UV rays from the sun will eventually bleach the dye, turning it into clear diesel. However, it is important to note that this process may not work for newer types of dye, which are more chemically stable.
While leaving fuel in the sun can be effective for removing the red dye, it is important to consider the potential drawbacks and risks associated with this method. One concern is the unknown impact of UV rays on the chemistry of the fuel. The sun's UV light can initiate various chemical reactions in the fuel that may have unintended consequences on its performance or safety. Therefore, it is essential to exercise caution when considering this method.
To ensure the safety of your fuel and vehicle, it is recommended to use a clear glass jar or bottle that can be sealed tightly. This will help prevent evaporation and reduce the risk of accidental spills. Additionally, it is crucial to keep the bottle out of direct sunlight when not in use, as prolonged exposure to UV rays can degrade the fuel over time.
It is worth noting that leaving fuel in the sun may not be a quick process, and it can take several weeks or even months for the dye to completely disappear. Therefore, if you are in a hurry, this may not be the best method for removing red dye from your fuel. Additionally, the effectiveness of this method may vary depending on the type of dye used and the stability of the fuel.
Overall, leaving your fuel tank in the sun is a potential solution for removing red dye, but it is important to carefully consider the risks and limitations before proceeding. It is always advisable to consult with a professional or seek alternative methods if you are unsure about the potential consequences.

Use a clay filter
While there are several methods to remove red dye from a fuel tank, using a clay filter is one of the most popular methods. This method involves filtering the dyed fuel through a clay-based substance, such as Fullers Earth or montmorillonite clay, also known as Aquagel. This process is similar to the one used by oil companies to create drilling fluid. The coloured liquid is filtered through the clay, resulting in a clear liquid output.
It is important to note that the effectiveness of this method may vary, and there are limited sources providing detailed instructions on the process. One source mentions that the clay used in drilling mud is typically bentonite, which can be purchased from suppliers like Halliburton under the name Montmorillonite clay or Wyoming Sodium Bentonite. However, finding smaller filters for this type of clay can be challenging, as most of the available options are for industrial use.
The process of using a clay filter to remove red dye from a fuel tank is not widely discussed, and there are concerns about the time and cost involved. Some people question whether the effort and expense of buying the clay, filtration media, and a filtering system outweigh the potential savings of avoiding road taxes. Additionally, there are doubts about the effectiveness of this method in removing the dye completely, as the dye can stain the fuel system, leading to issues like warranty denial.
Despite these concerns, some individuals claim to have successfully used clay filters to remove red dye from fuel. They mention that this method costs them around 28 cents per gallon, but specific details about the procedure are not provided. It is recommended to exercise caution and thoroughly research the process before attempting to use a clay filter to remove red dye from a fuel tank.
As an alternative to clay filters, some people suggest leaving the red diesel out in the sun, as prolonged exposure to sunlight can naturally bleach the dye over time. This method, however, may not be as effective or efficient as using a clay filter.

Drain the tank and blow the lines out
Draining the tank and blowing out the lines is a crucial step in removing red dye from a diesel tank. Here is a detailed breakdown of this process:
Draining the Tank
Start by draining the entire tank to remove any red-dyed fuel. The specific method may vary depending on the vehicle. For some vehicles, you may need to remove the fuel lines or access the tank through a drain plug. An easy and effective way to drain the tank is by using a siphoning pump. If you don't have access to a siphoning pump, a hand pump designed for fuel transfer can also be used.
It is important to ensure that the tank is completely empty, as any remaining fuel can affect the effectiveness of the cleaning process. Once the tank is drained, properly dispose of the fuel according to local regulations.
Cleaning the Tank
Red dye often leaves a residue on the tank's interior surfaces, which can be challenging to remove. Utilize a diesel tank cleaner designed to break down contaminants in fuel tanks. These cleaners are specifically formulated to address this issue.
Flushing the Fuel Lines
After the tank is clean and dry, the next step is to flush the fuel lines and fuel system. Disconnect the fuel lines from the tank and flush them with clean diesel or a fuel system cleaner. This step ensures that any leftover dye is removed from the lines.
Checking the Fuel Filter
The fuel filter may have captured some of the red-dyed fuel, so it is crucial to inspect it. If the filter is contaminated, replace it with a new one.
Refilling the Tank
Once the draining, cleaning, and flushing process is complete, refill the tank with clean diesel. It is recommended to fill the tank completely to ensure that any lingering traces of red dye are diluted.
Remember to always dispose of the contaminated fuel properly and follow local regulations to maintain environmental safety. By diligently following these steps, you can effectively remove red dye from your diesel tank and ensure your vehicle operates smoothly.

Replace plastic sight tubes
If you are looking to replace plastic sight tubes, there are a few options available. One user suggests replacing them with electronic devices, although they still prefer the tubes as they provide an absolute measure and can confirm the accuracy of electronic fuel gauges.
If you want to stick with plastic sight tubes, you can opt for clear fiber-reinforced plastic tubing, which is easy to change. Simply remove the top of the tube, blow into it to force the diesel back into the tank, and shut off the bottom valve when the tube is empty. Remember to place an absorbent pad underneath to catch any spills.
Another option is to use braided PVC sight tubes, which can be replaced with non-staining rigid polycarbonate. Polycarbonate is more durable than glass and is less likely to stain. You can also attach plastic electrical ties to wooden yardsticks at the back of each sight tube for easier calibration.
If you're looking for a long-lasting solution, consider using reinforced PVC. One user reported that their reinforced PVC sight tube remained clear after twenty years. To maintain clarity, you can blow down the open end and close the valve to prevent discoloration caused by dyes in the oil.
For those seeking a simple solution, nylon-reinforced PVC is an option, although it may become cloudy over time and is more expensive. Alternatively, nylon hydraulic hose resists chemical degradation from heating oil but can be challenging to fit due to its lack of elasticity.
Finally, if you prefer glass sight tubes, you may be able to find them at a plumbing supply house that caters to industrial/manufacturing customers. Glass sight tubes are common in industrial boiler plants, and while they may be more fragile, they provide clear visibility.
