Use a sump or wet-vac
If you have accidentally put diesel in your gas tank, one of the best ways to drain it is by using a sump or wet-vac. This method is particularly useful if you have dropped the tank and are struggling to get all the fuel out.
Firstly, locate and remove the fuel tank cap. This will allow air to enter the tank, facilitating the draining process. It will also prevent a vacuum from forming inside the tank, which would make it harder to drain.
Next, you will need to remove the fuel pump/sending unit. With the help of a lift jack, you can then remove the diesel tank. You can use gravity to get most of the fuel out, but you will need a sump or wet-vac to truly empty the tank. A sump or wet-vac will allow you to suck out the last remaining fuel.

Siphoning with a kit that includes a hose and hand pump
To drain diesel fuel from a gas tank, siphoning with a kit that includes a hose and a hand pump is a straightforward method. This process can be completed safely and effectively with the right tools and precautions. Here is a step-by-step guide:
First, ensure you have the proper equipment. You will need a siphon kit that includes a hand pump and a hose, also known as tubing. The hose should be made of durable material, such as PVC, and be long enough to reach from the gas tank to the fuel container. The kit should also include metal buckles or a hose clip to secure the connection between the pump and the hose, preventing leaks. Additionally, it is crucial to have a suitable fuel container to collect the drained diesel fuel. The container should be made of a material that is safe for storing flammable liquids, such as diesel fuel.
Before you begin, inspect the siphon hose for any damage, including kinks, cracks, or holes. A compromised hose can hinder the draining process and pose a risk of leaks. If the hose is damaged, replace it with a new one to ensure a safe and efficient drainage process.
Now, you are ready to start siphoning. Place the fuel container on the ground, ensuring it is at a lower level than the gas tank. This positioning will allow gravity to aid in the siphoning process. Connect the hose to the hand pump securely using the provided metal buckles or hose clip. Then, run the hose from the tank to the container, making sure there are no kinks or bends that could obstruct the flow.
Once the setup is complete, you can begin pumping. Most hand-operated pumps require only a few pumps to initiate the flow of diesel fuel. After that, the fuel should flow freely due to gravity. Be cautious and monitor the container as the siphoning process can be quite rapid. When the container is almost full, raise it to the level of the gas tank to stop the flow of fuel. This action will cause any residual fuel in the pump to drain back into the tank.
Finally, when you have finished siphoning, remove the siphon pump from the tank. Ensure that the tubing is free of excess fuel before detaching it. Close the gas tank securely and seal the fuel container to prevent any spills or leaks. Clean up any spills immediately with a fuel-safe cleaner.
