Removing the fuel tank from a 2002 Dakota Quad Cab can be a challenging task. While some sources suggest that it is possible to access the fuel pump by removing the truck bed, others emphasize that the fuel pump is located under the cab, and dropping the tank is necessary. One user reported that they were able to lift the tank using jacks but faced challenges with aligning the straps and bolts due to the tank's expanded width. They considered using a spreader to compress the tank slightly. Another user recommended draining the tank to reduce the weight and alleviate the bowing effect, making it easier to position the straps. Overall, the process of removing the fuel tank from a 2002 Dakota Quad Cab can vary depending on the specific model and the approach taken.

What You'll Learn

The tank may be too big for the straps
If the fuel tank seems too big for the straps, there are a few potential solutions. Firstly, ensure that the straps are placed in the correct order and position. The tank should be sitting correctly forward and aft, and the straps should reach around the tank and sit in the correct left and right positions.
If the straps are in the correct position, the issue may be that the tank has expanded due to the weight of the fuel. In this case, you could try draining the tank to reduce the weight and see if that allows the straps to fit. Another suggestion is to keep the tank outside in a cold environment overnight to help compress it, while keeping the straps inside, and then attempt to fit them in the morning.
If the above solutions do not work, you may need to use a tool to leverage the straps into place. One suggestion is to use a stout screwdriver in the strap hole and the hole on the frame to pull the strap into place. Alternatively, a ratchet strap can be used to secure the tank temporarily. However, if the tank is too heavy, it may be necessary to use a jack to support the weight and prevent it from dropping to the ground.

Try keeping the tank outside in the cold overnight
Keeping the fuel tank outside in the cold overnight is a strategy that can be employed when dealing with fuel tank removal and reinstallation issues in a 2002 Dakota Quad Cab. This approach is suggested in response to challenges with the tank straps, which may not align with the bolt holes as expected.
By exposing the fuel tank to cold temperatures, it is possible to induce a slight contraction in the tank's dimensions. This contraction effect is more pronounced when the tank contains a significant amount of fuel, such as the approximately 10 gallons mentioned in the source. The contraction can help alleviate the issue of the tank seeming too big to fit comfortably within the straps and facilitate a better alignment with the bolt holes.
It is worth noting that this method may be more effective in colder climates or during winter. Additionally, it should be combined with proper strap placement and sequence, ensuring that the left and right positions are correct.
While this approach can aid in the removal and reinstallation process, it is important to be cautious about potential condensation issues when exposing the fuel tank to cold temperatures, especially if the tank is not sufficiently full. Condensation can lead to water dripping into the fuel, causing potential issues with fuel lines and the fuel pump. Therefore, it is generally recommended to keep the gas tank at least half full during winter to prevent these issues.
In summary, keeping the fuel tank outside in the cold overnight can be a useful tactic when encountering difficulties with fuel tank strap alignment during removal and reinstallation in a 2002 Dakota Quad Cab. However, it should be complemented with proper strap positioning and maintaining adequate fuel levels to mitigate the risks associated with condensation in cold weather.

Drain the tank
If you are removing the fuel tank of a 2002 Dakota Quad Cab, you must drain the tank. The tank of a 2002 QC holds about 10 gallons of fuel, which is equivalent to 67lbs. This weight is enough to bow the sides and bottom of the tank. To drain the tank, you can stick a screwdriver in the strap hole and the hole on the frame, and use it as a lever to pull the strap into place.
If you are having trouble with the tank straps, you might have swapped them, so check that they are in the correct order. You could also try leaving the tank outside in the cold overnight and keeping the straps inside, so that they are easier to work with in the morning.
If you are removing the tank to access the fuel pump, you must drop the tank as the pump is under the cab. You can use a wood carrier for a floor jack to lower and raise the tank.

Drop the tank with a QC
Dropping the tank of a 2002 Dakota Quad Cab is a necessary step when replacing the fuel pump. This is because, even if you remove the bed, the fuel pump remains partially hidden under the cab.
To lower or raise the tank, you can use a couple of jacks to lift it. One user reported making a wood carrier for their floor jack to lower and raise the tank. If the tank is too big for the straps, you can try keeping it outside in the cold overnight and keeping the straps inside, then doing it first thing in the morning. This is because the plastic used for fuel tanks can bow out a bit, and even 10 gallons of fuel (67 lbs) can be enough to push the sides and bottom out slightly.
Once the tank is dropped, you can unhook a vac hose or two and then unplug the fuel pump from the harness plug. You can then drag the tank out from under the truck.

Unhook a vac hose or two and unplug the fuel pump
To remove the fuel tank in a 2002 Dakota Quad Cab, you will need to unhook a vacuum hose or two and unplug the fuel pump. This process can be done by following these steps:
First, remove the truck bed. This will provide access to the fuel pump, which is located under the cab. There are eight bolts holding the bed in place, which can be easily removed with a socket, air wrench, and extensions. If you don't have access to an air wrench, a regular ratchet and some elbow grease will also do the trick. Remember to unhook the tail lights and backup lights by unplugging them.
Once the truck bed is removed, you will have better visibility and access to the fuel pump. Locate the vacuum hose(s) and carefully unhook them. There should be one or two of these hoses, depending on your specific model. Be gentle and take your time to avoid any damage.
With the vacuum hose(s) unhooked, you can now focus on the fuel pump. It is held in place with a screw-type mechanism, similar to the lid on a mason jar. While there are special wrenches designed for this purpose, a rubber mallet and a chisel can also do the job. Using a rubber mallet helps to avoid creating sparks, which is important for safety reasons. Gently tap the raised edges of the screw mechanism with the chisel to loosen and unscrew it.
Now that the fuel pump is unplugged, you can proceed with any necessary replacements or repairs. It is important to be cautious and patient throughout this process to ensure a safe and successful outcome.
