Installing a drain in a plastic fuel tank can be challenging due to the potential risk of leaks. While some suggest using a pump and tube inserted through the fuel filler, others recommend against drilling into the tank and instead suggest using a gas shutoff valve similar to those found in lawnmower tanks. This option can be purchased at lawnmower service facilities or online.

What You'll Learn
Challenges of locating and sealing a drain
One of the primary challenges of locating and sealing a drain in a plastic fuel tank is ensuring that the tank is thoroughly cleaned and free of any fuel or fumes before beginning the repair. This process can be time-consuming and labour-intensive, requiring the tank to be removed and properly ventilated to prevent any ignition risks.
Another challenge is selecting an appropriate sealant that is compatible with the plastic fuel tank and resistant to the fuel and other chemicals it contains. It is crucial to choose a sealant that can form a strong, permanent bond with the plastic surface, such as JB weld or a chemical-resistant sealant recommended for fuel tanks.
Additionally, it can be difficult to locate a commercially available drain valve specifically designed for plastic fuel tanks. While gas shutoff valves commonly used in lawnmower tanks may be an option, they may not be suitable for draining all the contents of the tank due to the presence of a standpipe inside.
The repair process may also require creative solutions to seal the drain effectively. For example, one solution involves using a soldering pen and strips of a milk jug to seal the drain, while another suggests screwing a small sheet metal plate over the area to hold the sealant in place. However, these repairs may only be temporary fixes, and a complete replacement of the fuel tank may be the most reliable solution in the long run.
Finally, it is essential to consider the environmental impact of draining fuel from a vehicle. Proper disposal methods must be followed, and fuel should never be drained onto the ground or into storm drains, as this can contaminate water sources and harm the environment. Instead, individuals should contact their local council or waste oil recycling collection point to ensure the responsible disposal of drained fuel.

Using a gas shutoff valve
A gas shutoff valve can be used to drain a plastic fuel tank. These valves are commonly used in plastic lawnmower tanks and can be purchased at any lawnmower service facility or online. The valve mounts through a hole in the tank with a rubber grommet to seal it.
To install a gas shutoff valve, first identify the material of your plastic fuel tank. This is important because you will need to find a nut made of the same material or one that can be bonded with the appropriate glue. The nut should be glued to the outside of the tank so that it can accept a plug or petcock.
When installing the gas shutoff valve, keep in mind that you will need to find a way to avoid having a short standpipe inside the tank. This is because anything that passes through to the inside of the tank may prevent you from draining all the contents completely.

Using a pump and tube
Firstly, you will need to source a suitable pump and a thin tube. The tube should be thin enough to fit inside the fuel filler. You will also need a fuel tank adapter and a fuel line. These tools should be widely available at hardware stores or online.
Once you have the necessary equipment, you can begin the process. Insert the tube into the fuel filler, ensuring it reaches the bottom of the tank. Then, connect the tube to the pump and place a container at the pump's outlet to collect the drained fuel. Turn on the pump, and the fuel will be extracted through the tube and pumped into the container.
It is important to be cautious when performing this task, as fuel is highly flammable and toxic. Ensure you are in a well-ventilated area and take the necessary precautions to avoid any spills or leaks.
Additionally, consider the potential challenges of locating and sealing the drain. You may want to examine how tank senders are fitted, as this can provide insight into the sealing process. Understanding the material of your tank can also help determine the best sealing method, such as finding a compatible glue or gasket.

Removing the fuel level sender
Preparation:
Before starting, it is crucial to take safety precautions as you will be dealing with highly flammable gasoline. Disconnect the negative battery cable to prevent any electrical sparks. Roll down all the windows of your vehicle and work in a well-ventilated area to avoid inhaling fumes. You may also choose to wear a professional respirator for added protection. Cover part of the work area inside the car with plastic and an old towel to catch any escaping fuel.
Locating the Fuel Level Sender:
The fuel level sender is located inside the fuel tank, but it can usually be accessed from the top of the tank, under the backseat or the carpet in the trunk. Remove the backseat or trunk carpet to locate the access cover for the fuel level sender. The access cover is typically held in place with a couple of screws, so remove them and take off the cover to reveal the fuel level sender.
Once the fuel level sender is exposed, you will notice a wiring harness plugged into the top, which communicates with the fuel gauge to indicate the fuel level. Detach the wiring harness carefully. The fuel level sender may also have a long rod with a float at the end, so you might need to try different angles to remove it smoothly. Be cautious not to spill any fuel and always ensure there are no sources of spark or flame nearby.
Final Steps:
After removing the fuel level sender, it is recommended to clean any dirt or debris around the fuel pump and sender mounting area. You may also need to remove the mounting bolts to the fuel pump and sender, and pull them out of the fuel tank. Remember that installation of the new fuel level sender is simply the reverse of this removal process, and don't forget to plug in the new sender.
It is important to note that this is a general guide, and specific steps may vary depending on your vehicle's make and model. Always refer to your vehicle's repair manual for detailed instructions specific to your car.

Using a hose
First, ensure you have suitable containers and enough of them, such as 25-litre plastic drums or 20-litre jerrycans. It is important to have more containers than you think you need to avoid spills.
Next, insert the hose into the filler neck of the fuel tank. You will need approximately three feet of 5/8" I.D. hose. If your car has a metal tank, you may need to raise the rear of the car and support it with jack stands to access the tank.
If you are using an electric pump, connect it to 12 volts. You can then start pumping the fuel out. If you do not have a pump, you can use your mouth to suck on the other end of the hose to start the flow of fuel. However, this method is hazardous and not recommended, as it can result in swallowing gasoline or creating a fire hazard.
As you pump, hold onto the end of the hose, as it can start to move when the fuel begins to flow. Place a container at the other end of the hose to collect the fuel. You will not be able to drain all of the fuel using this method, but you should be able to remove enough to make the tank easily manoeuvrable.
Finally, turn off the pump and safely store your equipment. Properly dispose of the drained fuel by contacting your local environmental waste disposal centre. Do not pour the fuel down a drain or sewer.

Frequently asked questions
Installing a drain in a plastic fuel tank can help remove accumulated water and other contaminants from the bottom of the tank, improving fuel quality and engine performance.
It may be challenging to locate and seal the drain properly, and there is a risk of persistent leaks. Plastic fuel tanks are susceptible to water in the fuel, and a drain may not be necessary if proper maintenance is carried out.
One method is to use a hose and a container. Insert the hose into the tank and suck on the other end to start the flow of fuel, then transfer it to the container. Another method is to use a manual pump, a fuel tank adapter, and a fuel line to force the fuel out of the tank into a container.
You can use a gas shutoff valve similar to those found in plastic lawnmower tanks. These valves mount through a hole in the tank and are sealed with a rubber grommet. You can also explore options such as tank senders, which use an inner flange slotted through a hole and sealed with gaskets.
