What You'll Learn

The cost can be upwards of $2500
The cost of draining a fuel tank can vary depending on several factors, including the make and model of the vehicle, the location, and the complexity of the job. In some cases, the cost can be upwards of $2500, which may seem extremely high. However, it is important to consider the labour involved in removing, draining, and reinstalling the fuel tank, especially if it is a complex or time-consuming process.
For example, if you have accidentally filled your diesel vehicle with gasoline, as in the case of a 2017 F-350 Powerstroke, the local dealer may quote you $2500 to fix the problem. This price may be justifiable if you are unfamiliar with the process and are not capable of doing it yourself, or if you are in a hurry and need to get the problem fixed quickly.
In such cases, it may be worth considering alternative options to reduce the cost. One option is to get quotes from multiple shops or dealers in your area and compare prices. You can also inquire about the possibility of simply draining the contaminated fuel from the tank, which may be a cheaper solution if no major parts need to be replaced.
Additionally, if you feel comfortable with basic automotive maintenance, you may be able to perform the fuel drain yourself. This could involve using a siphon to remove the incorrect fuel type and then refilling the tank with the correct fuel. However, it is important to exercise caution and ensure you have the necessary knowledge and equipment to perform such tasks safely.
While a $2500 quote for draining a fuel tank may seem high, it is important to weigh the costs and benefits based on your specific circumstances. By exploring different options and seeking advice from knowledgeable sources, you can make an informed decision that best suits your needs and budget.

It depends on the labour required
The cost of draining a fuel tank depends on several factors, including the labour required and the method used. If you take your vehicle to a mechanic or dealer, the cost will typically include labour for removing, draining, and reinstalling the fuel tank, as well as the disposal of the drained fuel.
In some cases, the labour cost may be the most significant factor in the overall repair cost. For example, a dealer quoted a price of $2500 to remove, drain, and reinstall a fuel tank, which was considered extremely high by the customer. However, this price may be justifiable if the job requires specialized skills or equipment that the dealer has access to.
On the other hand, if you choose to drain the fuel tank yourself, the labour cost can be significantly reduced or eliminated. Some people suggest siphoning the fuel out of the tank, which can be done with a clear hose, a ball siphon, or other siphoning tools. This method may require some time and effort but can be a cost-effective alternative to hiring a professional.
Additionally, the labour cost may depend on the specific vehicle and the accessibility of the fuel tank. For instance, dropping a fuel tank on some vehicles can be relatively easy and can be done with basic tools, while other vehicles may have more complex fuel systems that require advanced knowledge and techniques.
It's important to note that labour rates can vary depending on your location and the service provider you choose. It is always recommended to get multiple quotes from different mechanics or dealers to get a better understanding of the labour costs involved in draining a fuel tank.

Removing the supply line is an option
The cost of draining a fuel tank can vary depending on several factors, such as the make and model of the vehicle, the severity of the issue, and the labour and parts required. In some cases, the cost may be as low as a couple of hundred dollars, while in other cases, it could be significantly higher, such as $2500 as quoted by a Ford dealer. This high cost is likely due to the labour-intensive nature of the job, as one source suggests.
Firstly, locate the supply line going to the fuel filter. You may need to jack up the vehicle to access the underside of the car safely. Ensure you are also equipped with the necessary tools and safety equipment, such as gloves and eye protection.
Next, carefully remove the supply line. Depending on the vehicle, you may need to disconnect the fuel filler tube if it has anti-fuel theft measures in place. Once the supply line is disconnected, you can use the fuel pump to pump out the contaminated fuel. Place a container underneath the fuel tank to collect the drained fuel.
After removing the contaminated fuel, it is essential to dispose of it properly. Do not pour it down the drain or onto the ground. Instead, take it to a certified disposal facility or recycling centre. Some cities have specific sites or designated days for hazardous waste collection.
Once the tank is empty, you can then refill it with fresh fuel. Before refilling, it is good practice to clean the tank and ensure that all connections are secure and properly tightened to prevent leaks. You may also need to bleed the fuel system to remove any air that may have entered during the process.
Finally, it is important to note that this process may vary depending on the vehicle's specific make and model. Always refer to the vehicle's repair manual or seek professional assistance if you are unsure about any steps. Additionally, some vehicles may have a fuel test port under the hood, allowing for an alternative method of draining the fuel tank.

Siphoning the tank is a cheaper alternative
The cost of draining a fuel tank can vary depending on the vehicle and the complexity of the job. In some cases, the cost can be as high as $2500 to remove, drain, and reinstall a fuel tank, which may include labour and disposal costs. However, there may be cheaper alternatives, such as siphoning the tank yourself.
While siphoning a fuel tank can be a risky and potentially dangerous task, it can be a cheaper alternative to paying for professional drainage. It is important to note that siphoning gas may be illegal in some states or areas, so it is crucial to check the local laws before attempting this method. Additionally, improper siphoning can damage your vehicle, so it must be done correctly and with caution.
To siphon a fuel tank, you will need a length of tubing that is long enough to reach from the gas tank to a container on the ground, as well as a pair of pliers. The fuel tank is typically located beneath the car, near the rear wheels. Insert one end of the tubing into the gas tank through the fuel filler neck, ensuring that it is secure and reaches the bottom of the tank. Then, insert the other end of the tubing into the container.
Using a small air compressor or bike pump to create pressure in the container can help draw the gas out of the tank and into the container. However, this method should be approached with caution, as too much pressure can cause the gas tank to rupture or explode. It is recommended to use a manual or electric pump for a safer and more efficient gas transfer.
By siphoning the fuel tank yourself, you can avoid the labour and disposal costs associated with professional drainage. However, it is important to weigh the risks and legal considerations before attempting this method.

The cost of fuel must also be considered
In some cases, the cost of fuel can be a significant portion of the overall cost of draining and servicing a fuel tank. For instance, a user on a Ford Powerstroke Diesel forum was quoted $2500 to remove, drain, and reinstall the fuel tank on their 2017 F-350 Powerstroke after mistakenly pumping 13 gallons of gas into it. While this cost may seem high, another user in the same forum thread suggested that it is not unreasonable given the labour involved.
Additionally, the type of fuel and the sensitivity of the engine can impact the cost. For instance, one individual shared their experience of working at a truck stop, where employees often added a gallon of gas to diesel tanks to "clean out the engine." However, they noted that newer engines may be more sensitive to this practice.
It is worth noting that there are alternative methods to draining a fuel tank that can be more cost-effective. For example, one individual suggested using a ball siphon to drain 27.5 gallons of fuel from their vehicle, which only required them to purchase gas cans capable of holding 30 gallons of fuel. Another user suggested a cheaper method involving jumping the fuel pump relay or actuating it with a scan tool to pump out the fuel, which would only require paying for fuel and a couple of hours of labour.
Therefore, when considering the cost of draining a fuel tank, it is important to factor in the cost of fuel, the labour involved, and the potential for alternative, more affordable solutions.
