Draining the fuel tank of a Volvo V70 can be a tricky task. While some suggest using a hand crank pump and a long hose to drain the tank, others recommend removing the fuel pump, which can be a lot of work. Another method is to disconnect the fuel line at the filter and route it into a gas can, but this can be tricky without special equipment. Some people have also suggested using a cheap battery fuel pump to drain the tank, which can be effective in removing most of the fuel. It is important to note that simply letting the fuel sit in the tank for extended periods can cause issues, so regular maintenance and draining, when necessary, is essential.

What You'll Learn
Use a hand crank pump and a long hose
Draining the fuel tank of a Volvo V70 can be done in several ways, one of which is by using a hand crank pump and a long hose. Here is a step-by-step guide on how to do it:
First, you will need to access the fuel tank. This may involve pulling out the back seat of the car to expose the fuel tank. Make sure you have a container ready to collect the drained fuel. Place the container on the ground near the car, ensuring it is secure and will not tip over.
Next, attach the hand crank pump to the hose. The hose should be long enough to reach from the fuel tank to the container. Insert the hose into the fuel tank. You may need to remove the fuel cap or use an adapter to ensure a tight fit. Crank the pump according to the manufacturer's instructions to begin pumping the fuel.
As you pump, keep an eye on the fuel level. Tapping the tank from underneath can help you determine how much fuel is left, along with observing the fuel gauge and low fuel light. Continue pumping until you have removed as much fuel as possible.
Once you have finished pumping, remove the hose from the fuel tank and place it into the container to drain any remaining fuel. Ensure that you dispose of the drained fuel responsibly and according to local regulations.
It is important to note that draining a fuel tank can be a dangerous task due to the flammable nature of fuel. Always take the necessary precautions, such as working in a well-ventilated area and avoiding any sources of ignition. Additionally, be sure to recycle or dispose of the drained fuel properly, as it can be harmful to the environment if not handled correctly.

Disconnect the fuel line at the filter
Disconnecting the fuel line at the filter is a method to drain the fuel tank of a Volvo V70 without the use of special equipment. To do this, first locate the fuel filter and fuel line. Once located, you can disconnect the fuel line at the filter. Ensure that you have a gas can ready to collect the fuel. After disconnecting the fuel line, turn the key forward and let the fuel pump do its work.
It is important to note that when the fuel level gets low, below a quarter of a tank, you should run the engine for short periods, then turn off the key, and repeat this process. This will help ensure that the fuel is drained effectively.
Additionally, consider replacing the fuel filter if possible, as it can contain residual fuel. Draining the fuel tank and changing the filter can help remove any contaminated fuel from the system.
Furthermore, to ensure the fuel is completely drained, you may need to undo both ends of the fuel line and blow low-pressure air through it. This will help remove any remaining fuel from the line.
By following these steps, you can effectively drain the fuel tank of a Volvo V70 by disconnecting the fuel line at the filter.

Remove the rear seat and lift pump
To access the fuel pump in a Volvo V70, you will need to remove the rear seat and create an access hole in the metal undercarriage above the fuel tank. First, lift the rear seat to uncover a metal plate held in place by four 10mm bolts. Remove this metal plate. Underneath, you will find a black plastic cap with a white plastic cap in the middle. This is the fuel tank cap.
To remove the fuel tank cap, you will need to fashion a spanner to remove the retaining ring. The retaining ring is the black outer ring with teeth that accept the spanner. Tapping alternate sides might work to loosen and remove the retaining ring, but this method is not ideal, especially when putting it back together.
With the fuel tank cap removed, you will now need to create an access hole for the fuel pump. This will require the use of a grinder, so ensure you are wearing appropriate safety gear, including eye protection and gloves. The fuel tank must also be almost empty to minimise the risk of gas fumes during this process.
Once the access hole is created, you will be able to access the fuel pump for replacement or further maintenance. Be sure to consult additional resources and take appropriate safety precautions before proceeding with any fuel-related work.

Use a cheap battery fuel pump
To drain the fuel tank of a Volvo V70, one method is to use a cheap battery fuel pump. This can be done by accessing the fuel tank from the back seat.
Firstly, pull out the back seat to reveal a metal plate held by four 10mm bolts. Underneath this plate, there is a black plastic cap with a white plastic cap in the middle. This inner cap has an arrow moulded onto it, which needs to be aligned with another arrow or mark on the outer cap. To turn these caps, you may need to fashion a spanner to grip the teeth of the outer ring.
Once the caps are open, you can insert the battery fuel pump. Ensure you have a pump with a long hose to reach the bottom of the tank. Pump out as much fuel as possible, and then use a sponge to soak up the remaining fuel.
It is important to note that there are two pumps in the unit, one that sucks directly and another that uses a hose on the other side of the tank. When draining, you only need to remove the driver's side, but if you remove both, tie a string to the hose to help guide it back.
Additionally, be cautious when dealing with fuel and ensure the area is well-ventilated.

Drain and change the fuel filter
Draining and changing the fuel filter on a Volvo V70 is a relatively straightforward process that can be done at home. It is important to note that the fuel filter location may vary depending on the model year and engine type of your Volvo V70. For example, some models have a steel fuel tank with the fuel filter located inside, while others have an external fuel filter.
To begin the process of draining and changing the fuel filter, you will need to locate the fuel filter. For Volvo V70 models with a steel fuel tank, the fuel filter is located inside the tank and can only be accessed by removing the fuel pump. If your vehicle has a plastic fuel tank, the fuel filter is typically located near the fuel tank on the passenger side or just ahead of the right rear wheel, bolted to the underbody.
Once you have located the fuel filter, follow these steps:
- Place a drain pan under the fuel filter to catch any spilled fuel.
- Release the fuel pressure via the Schrader valve on the fuel rail. Look for a car tire-style air cap, which is sometimes blue. Be sure to wear eye protection during this step.
- Remove the fuel filter bracket using the appropriate size bolt.
- Disconnect the fuel lines from the fuel filter. You may need to use a trim panel tool to release the friction-style fuel line clamp.
- Allow the remaining fuel to drain into the drain pan.
- Clean the threads on the fuel filter clamp fastener and apply a penetrating oil. Let it sit for about 10 minutes before removing the fastener.
- Install the new fuel filter into the clamp, ensuring that the fuel lines are securely attached.
- Check for fuel leaks and wipe up any spilled fuel.
It is important to note that you should always properly dispose of any fluid waste and recycle parts and packaging when possible. Additionally, if you are working with the electrical system, it is recommended to disconnect the battery before beginning.

Frequently asked questions
There are a few ways to drain the fuel tank of your Volvo V70. One way is to use a hand crank pump and a long hose to stick into the fuel tank and pump out the fuel. Another way is to remove the back seat, undo the lift pump, and use a hose to drain the tank. You can also try disconnecting the fuel line at the filter and routing it into a gas can, then turning the key forward to let the fuel pump run.
It is not necessary to completely drain your fuel tank if you have mistakenly put petrol in it. A 1-2% mix of petrol in a diesel tank will not blow up your engine. However, you should try to pump out as much petrol as possible and then fill the tank with diesel and drive to burn off the remaining petrol.
When draining your Volvo V70 fuel tank, you can tap the tank from underneath to determine if it is empty, along with using the fuel gauge and low fuel light.
