Draining the fuel tank of a Dodge Dakota can be a tricky task. The process may involve removing the bed bolts and sliding the bed to access the tank, or even dropping the tank completely. Some people suggest using a siphon pump or a regular electric fuel pump to remove the fuel, but it's important to note that these methods may not be spark-protected, which could be dangerous. Other suggestions include hard-wiring the fuel pump to a battery and letting it pump the contents out through the fuel line, or using a scan tool to activate the fuel pump and drain the tank. It's always a good idea to consult a professional mechanic or a trusted forum for specific instructions and safety precautions before attempting any fuel tank drainage.
How to Drain a Fuel Tank on a Dodge Dakota
| Characteristics | Values |

| Pump safety | Ensure protection from sparks and fire |
| Manual method | Disconnect fuel inlet hose, feed in a siphon hose, and use a container to collect the fuel |
| Alternative manual method | Remove bed bolts, slide the bed back, jump the fuel pump relay, and disconnect the fuel supply line |
| Other suggestions | Hard-wire the fuel pump to a battery, disconnect the fuel line, and run a rubber hose to a container |
| Additional considerations | Access the top of the tank by removing bolts and sliding the bed back |

What You'll Learn
Disconnect the fuel inlet hose and insert a siphon hose
To drain a fuel tank on a Dodge Dakota, you will need to disconnect the fuel inlet hose and insert a siphon hose. This process can be tricky, as Dodge vehicles have used anti-siphon technology for years, and you will need to work around the anti-siphon valve in the tank.
Firstly, locate the fuel inlet hose. This is where the incoming fuel enters the tank. Once you have found the inlet hose, you will need to remove it. Be careful not to damage the anti-siphon valve located in the inlet hose. This valve is designed to keep the tank from draining in the case of a rollover, so it is important to work carefully around it.
After removing the fuel inlet hose, you can insert your siphon hose. Choose a hose that is compatible with your vehicle and fuel type. You may need to trim or adjust the length of the hose to ensure a proper fit. Make sure the hose is securely connected to avoid any leaks.
Once the siphon hose is in place, you can begin the process of siphoning the fuel. This may require some physical effort, such as pumping or sucking on the hose, to get the fuel flowing. Have a container ready to collect the drained fuel. Ensure that the container is suitable for storing fuel and that you are working in a well-ventilated area.
If you are having trouble accessing the fuel inlet hose or the tank itself, you may need to remove some parts of your Dodge Dakota. This could include removing the bed bolts and sliding the bed back to access the top of the tank. Alternatively, you could try disconnecting the fuel supply line and lengthening it to reach your container. Remember to work carefully and consult a professional if you are unsure about any steps.

Remove the bed bolts and slide the bed back
To remove the bed bolts and slide the bed back, you will need to locate the bolts. There are eight bolts in total, four on each side of the frame. One user noted that three bolts were in an open space, while the fourth was tucked away but could be accessed with a socket.
Once you have located the bolts, you can begin to remove them. It is important to also disconnect the taillight wiring harness and the fuel filler hose. The fuel filler hose is connected by either one screw or three torx screws, depending on the size of your gas tank.
After all, the bolts and connections have been removed, you can now slide the bed back. One user noted that they were able to slide the bed back three feet, allowing them to rest on the tires. This process should only take about 10-15 minutes.
If you are working on a sloped surface, it is recommended to chock the back wheel to prevent the truck from rolling. Additionally, always set the parking brake before beginning any work.

Jump the fuel pump relay and disconnect the fuel supply line
To drain a fuel tank on a Dodge Dakota, one method is to jump the fuel pump relay and disconnect the fuel supply line. This process involves bypassing the fuel pump relay switch by connecting the positive terminal of the battery directly to the fuel pump, and then disconnecting the fuel supply line to drain the fuel.
- Locate the fuel pump relay in the fuse box. The fuel pump relay is typically labelled and can be identified by its location in the fuse box.
- Remove the fuel pump relay from the fuse box. This will expose the metal terminals behind it.
- Using a jumper wire or a small gauge wire, connect the positive terminal of the battery to the metal terminal on the fuel pump relay that corresponds to the pump activation wire. This will bypass the relay and provide power directly to the fuel pump.
- With the jumper wire connected, the fuel pump should turn on. You can verify this by listening for the sound of the pump or by checking for voltage at the pump terminal.
- Once the fuel pump is activated, locate the fuel supply line. This is the line that carries fuel from the tank to the engine.
- Disconnect the fuel supply line by carefully removing any clamps or fittings that hold it in place. Be prepared for some fuel to spill out when you disconnect the line.
- Place a container to catch the drained fuel. You will need a container that is large enough to hold the amount of fuel you plan to drain and is compatible with fuel, such as a gas can or a bucket.
- Direct the disconnected fuel supply line into the container and allow the fuel to drain out. You may need to lengthen the fuel supply line to reach the container.
- Once the fuel has finished draining, carefully reconnect the fuel supply line and secure any clamps or fittings that were removed.
- Finally, remove the jumper wire from the fuel pump relay and battery, and replace the fuel pump relay in the fuse box.
It is important to exercise caution when working with fuel and electricity. Ensure that you take the necessary safety precautions, such as wearing protective gear and working in a well-ventilated area, to prevent accidents or injuries.

Use a regular electric fuel pump
One way to drain the fuel tank of a Dodge Dakota is to use a regular electric fuel pump. This method is recommended by a user on the Dodge Dakota Forum, who highlights the dangers of using a siphon pump, which is not protected from sparks and fire if some gas is loose.
To use an electric fuel pump, first disconnect the fuel line from the rail and run a rubber hose from the fuel line to a container that can hold the drained fuel. Then, hardwire the electric fuel pump to a battery, and let the pump empty the tank through the fuel line.
Alternatively, you can use the fuel pump in your tank to push the fuel out. To do this, hook up a line to the fuel rail and use the pump to push the fuel out. Once the fuel is out, you can clean the tank and put in fresh fuel.
Another method involves jumping the fuel pump relay and disconnecting the fuel supply line. Lengthen the fuel supply line to reach a container that can hold the drained fuel.
If you have a standard cab with a 6.5 bed, you can remove the bed bolts and slide the bed back to access the top of the tank. Then, remove the fuel sending unit/pump combo and siphon off the gas through that opening.

Remove the tank and siphon manually
To manually siphon the fuel tank of a Dodge Dakota, you will first need to remove the tank. This can be a complex process, so it is recommended to have a second person available to help.
Start by removing the bed bolts and sliding the bed of the truck back, giving you access to the top of the tank. If you have a standard cab and 6.5 bed, you should be able to slide the bed back by about 6 inches. Once you have access to the tank, remove the fuel sending unit/pump combo.
With the pump removed, you can now siphon the fuel from the tank. Be cautious when inserting the siphon hose, as the tanks have anti-siphoning valves that can be damaged if something is jammed down the inlet tube. Feed the siphon hose into the fuel inlet hose, taking care not to damage the rollover valve, which is designed to keep the tank from draining in the event of a rollover.
If you are unable or unwilling to remove the tank, another option is to hook up a line to the fuel rail and use the fuel pump to push the fuel out. This method can be done without removing the tank but may be more time-consuming.
Make sure you have a bucket or other container to collect the drained fuel.
