What You'll Learn

Using a fuel transfer pump
When using a fuel transfer pump, you will find a filter at one end to ensure no debris is transferred through the pump, and a trigger at the other end, similar to the type found at a petrol station. To begin the process, place the filter end into the oil tank until it reaches the bottom. Then, place the trigger end into the new tank or a drum. If you are using a battery, connect the alligator clips, red to positive and black to negative. Press the button on the pump to start the transfer.
If you are transferring oil into drums, be careful, as a 25-litre drum will fill up quickly. Be ready to depress the trigger and turn off the pump before moving to the next drum. Turn the pump back on and press the trigger to transfer the oil into the next drum. As the tank empties, the pump will slow down, and when the filter is not fully submerged in oil, the transfer will slow considerably. At this point, stop the pump and elevate the far end of the tank so that the remaining oil runs down towards the filter. Allow the oil to settle for 5 minutes to let any dirt and debris settle at the bottom before restarting the pump to drain the remaining oil.
There are various types of fuel transfer pumps available, such as 12-volt transfer pumps, drill-powered pumps, and hand-powered pumps. The cost of a fuel transfer pump can vary, ranging from £150 to £300, or $15 to $150, depending on the quality and type of pump. Additionally, there may be expenses for drums, which can cost £5-£8 per 20 litres or $15 for a 35-gallon drum. It is important to note that transferring heating oil from one tank to another may not be advised due to potential contamination or quality issues.

Preventing contamination
When transferring fuel oil from one tank to another, contamination is a key concern. Contamination can occur in several ways, and it is important to take steps to prevent it.
Firstly, sediment and sludge can accumulate at the bottom of the tank. This can clog fuel filters and cause issues in the new tank. To avoid this, it is recommended to leave the bottom 5-10 gallons of oil in the original tank, as it contains the most sediment. Alternatively, the oil can be filtered under pressure to flush out any sediment and tank bottom deposits, ensuring the oil is uncontaminated before transfer.
Another cause of contamination is microbial growth, which can include fungi, bacteria, and other microbes. This often occurs in diesel fuel tanks and can be challenging to eradicate. To prevent this, a biocide can be added to the fuel, particularly if there is a concern with biological growth.
Spillage is also a significant concern during the transfer process. Oil spills can lead to environmental contamination and must be avoided. To prevent spills, it is important to use the correct equipment and follow safety procedures. This may include using a barrel pump or hand-powered diesel pump, ensuring hose clamps are tight, and placing the hose connection in a container to collect any potential leaks.
Additionally, it is essential to consider the quality of the oil being transferred. If the oil in the original tank is contaminated, it can pass on the contamination to the new tank. In such cases, a filtration system may be necessary to meet quality standards and ensure the oil is free of impurities.
By following these measures, the risk of contamination during the transfer of fuel oil from one tank to another can be significantly reduced.

Avoiding spillage
Firstly, it is important to use the correct equipment. Employ the use of a siphon or transfer pump specifically designed for fuel oil transfer. These pumps can be inexpensive and easy to operate, either manually or with a power source. Ensure the hoses are securely connected to the pumps and tanks to prevent leaks.
Secondly, monitor the transfer process closely. Keep an eye on the filters, as sludge or debris can build up in the tanks, especially at the bottom. Avoid transferring the bottom portion of the oil, usually about 5 to 10 gallons, to prevent contaminating the new tank with sludge. If the new tank is in a different location, consider using a drum or container to temporarily hold the oil before transferring it to the new tank.
Additionally, maintain a safe distance between the two tanks during the transfer process. If possible, place the receiving tank at a lower level than the source tank to utilise gravity and reduce the risk of spillage. Also, ensure that the hose connections are secure and tight. As an extra precaution, consider placing the hose connection inside a large container or bucket to collect any potential leaks, reducing the risk of contamination.
Finally, be cautious when dealing with old tanks. It is not recommended to pressurise old tanks as it can lead to tank failure. Instead, consider using a vacuum transfer system that utilises pressure differences between the tanks to move the fluid. This method is useful when other transfer methods are impractical.
By following these steps and guidelines, you can effectively avoid spillage when transferring fuel oil from one tank to another, ensuring a safe and environmentally friendly process.

Using a siphon pump
Siphon pumps are an inexpensive and easy-to-use method for transferring fuel oil from one tank to another. They are available at most hardware stores and come in several varieties, including hand-operated, electric, and battery-powered options. The cost of a siphon pump can vary depending on the type, with some simple pumps costing less than $5 or £3.
To use a siphon pump, start by removing the 2-inch fill pipe and vent pipe from the old tank using a pipe wrench. These pipes are typically located in the centre of the top of the tank. Next, lower the inlet hose of the pump through the fill pipe of the old tank until it is immersed in the oil. Ensure that the hose clamps are tight to prevent any leaks during the transfer process.
Then, place the outlet hose of the pump into the fill pipe of the new tank. If the hose is not long enough, attach an additional length of hose and secure it with a clamp and a screwdriver. With the hoses in place, turn on the pump if it is electric, or squeeze the pump bulb or operate the pump lever if it is hand-operated. The oil should now begin flowing through the pump hoses and into the new tank.
It is important to keep the pump running until the old tank is empty to avoid spills. Once the transfer is complete, remove the inlet and outlet hoses from the tanks and reconnect the fill and vent pipes in the new tank. Properly dispose of the old tank by contacting your local building code inspector for guidance.
