What You'll Learn
Use a pump to empty the tank
Using a pump to empty a fuel oil tank is a common method, but there are a few things to consider. Firstly, it is important to determine the size of the tank and the amount of oil that needs to be removed. If you only have a small amount of oil left in your tank (around 10 to 15 gallons), you may be able to lift the tank onto blocks and use gravity to get the remaining oil out.
There are several types of pumps that can be used to remove fuel oil from a tank, including electric pumps, drill-powered pumps, and air-operated pumps. Electric pumps can be purchased or rented, but they need to be fuel-grade and able to handle flammable liquids. Drill-powered pumps are a more affordable option, but they require a drill and some old garden hose to operate. Air-operated pumps use air pressure to pump the fuel out and can be effective, but they must be used with caution as most tanks are not built to handle much pressure.
When using any type of pump, it is important to place the pump as low and as near the tank as possible. This will help to ensure that the fuel is sucked through the hose effectively. Additionally, clear plastic hose is recommended so that you can see what you are doing.
After the oil has been removed, it is important to properly dispose of the sludge that remains at the bottom of the tank. This can be done by cutting the tank open and scraping out the sludge by hand. The sludge can be recycled for use in heavy industrial capacities. Finally, don't forget to pump some soapy water through the pump to prevent any oil from remaining and causing issues later on.

Remove supply pipes and drag the tank out
Before removing a fuel oil tank, it is important to ensure that the tank is entirely empty. This is because fuel oil is highly toxic and flammable, and any accidental spills can be costly to clean up.
To remove the supply pipes, you will need to use pipe wrenches, a pipe cutter, or a reciprocating saw. All the pieces of pipe are threaded together, so you will need to turn them counter-clockwise to unscrew them. Start at the outside end, as this is the only place where you will be unscrewing one end. Be extremely cautious when cutting pipes as this can create hot metal or sparks, which could ignite the oil or its vapors.
Once the supply pipes are removed, you can drag the tank out. Depending on the size and weight of the tank, you may need assistance. For a 275-gallon tank, two people with lifting straps or two strong individuals should be sufficient. Be sure to brace the tank so that it doesn't roll over. If there is any fuel or sludge remaining in the tank, be prepared for a messy and smelly experience.
It is worth noting that removing a fuel oil tank is not a simple DIY task. There are strict regulations governing the removal and disposal of oil tanks, and it is recommended to hire a professional firm with the necessary expertise and permits to ensure the job is done safely and correctly.

Dispose of the tank through a certified company
Fuel oil tanks, especially those that are underground, pose a serious environmental hazard. They are also extremely toxic and flammable. Therefore, it is imperative that you engage a certified company to dispose of your fuel oil tank.
Firstly, you should contact your local removal contractor. They will use a special explosion-proof pump to extract any reusable oil from your tank. This oil can then be filtered and reused for heating. The removal contractor will then sever the tank's vent and fill pipes, removing them from the foundation and filling the holes with a concrete-patching compound.
Next, the empty tank will be taken to a state-certified yard, where it will be inspected and scrapped. Finally, the tank will be transported to a steel mill to be melted down.
Before engaging a company, it is recommended that you speak to at least three different contractors to ensure you are getting a good price and that everything is in order. It is also important to ensure that the company is permitted to work in your area and that they carry pollution liability insurance.
Depending on where you live, the removal of your fuel oil tank may be subject to strict regulations and require direct supervision from the state. Therefore, it is essential that you hire a certified professional to handle the disposal of your fuel oil tank.

Use a hose to drain the oil
Using a hose to drain fuel oil from a tank is a straightforward method that does not require any specialised equipment. However, it is important to note that this method carries some risks, such as inhaling toxic fumes or accidentally ingesting fuel. Therefore, it is recommended to exercise caution when attempting this procedure.
To begin, you will need to obtain a hose that is compatible with your tank's valve. A cheap washing machine hose with a garden hose adapter can be used, but avoid using a 3/4" pipe thread adapter as it may leak. Additionally, ensure that you have a container large enough to collect the drained fuel oil.
Once you have the necessary equipment, insert the hose into the tank securely. Do not suck on the hose to start the fuel flow, as this can be dangerous. Instead, blow gently into the hose, and you should hear air bubbling in the fuel. If you cannot hear bubbling, try inserting the hose further into the tank.
After establishing the airflow, connect the free end of the hose to a fuel transfer pump. These pumps are inexpensive and can be purchased online or at hardware stores. Position the container at the other end of the hose to collect the fuel. Start pumping, and the fuel will begin to drain from the tank into the container.
It is important to note that this process may not remove all the fuel from the tank. However, it will drain enough fuel to make the tank easily manoeuvrable. Always ensure that you are working in a well-ventilated area and take the necessary precautions to avoid any hazards associated with handling fuel oil.

Clean the tank and scoop out the sludge
Fuel oil is extremely toxic and flammable, so it is recommended to leave the removal of old oil tanks to professionals. However, if you want to remove sludge from your oil tank yourself, you will need to prepare some supplies and protective gear. It is recommended to wear gloves and old clothes that you don't mind getting greasy.
To clean the tank and scoop out the sludge, start by draining all the oil from the tank. Place a plastic bucket or a disposable container under the tank's drain valve and remove the valve cap. Let the oil flow into the bucket until the outflow stops. Seal the bucket and move it out of the way.
Next, loosen the sludge by spraying clean water into the tank. Continue spraying until the water dripping from the valve runs clear. Once all the water has drained out, use cleaning rags to wipe away any remaining sludge or grime from the inside of the tank. You can also use the rags to clean the outside of the tank, removing any dirt, grime, or leaves that may have built up. If you notice any rust on the exterior, clean it off and apply rustproof paint.
Now, you can use a cleaner to remove any stubborn sludge or grime. Trisodium phosphate (TSP) is a popular choice for cleaning oil tanks, but some states have restrictions on cleaners containing phosphates. Therefore, it is recommended to check your local regulations before using TSP. If you choose to use TSP or a similar phosphate-based cleaner, mix one cup of TSP powder with five gallons of water, and fill your tank with this solution. If you are using an alternative chemical, follow the instructions on the container for proper dilution.
After adding the cleaning solution, insert an air hose into the tank and start the air pump. Leave the pump running for at least 12 hours to allow the solution to work. Finally, open the valve and drain the solution from the tank. All the remaining sludge should now be washed out, and you can refill the tank with heating oil if desired.
