If you need to drain the gas tank of your Lincoln LS, there are a few methods you can try. One way is to use a siphon hose, which is inserted into the gas tank in the same way as a gas pump nozzle when filling up the tank. However, Lincoln LS fuel tanks have restrictors built into the filler tube, which may prevent a siphon hose from reaching the gasoline. In this case, you would need to use an electric motor-driven pump. Before attempting any of these methods, it is important to inspect the ground under the gas tank for any signs of a leak, as gasoline leaks can be extremely dangerous, leading to fires or explosions.

What You'll Learn
Release the gas tank latch, open the door, and unscrew the cap
To drain the gas fuel tank of your Lincoln LS, you must first release the gas tank latch and open the gas tank door. This can be done by hitting the button to open the gas tank door, or by using the release cable in the trunk, as outlined in the owner's manual. If the button method does not work, you may need to replace a small piece of flat metal (a spring) that pushes the door open when the button is pressed.
If the gas tank door does not pop open, you can try prying it open with your key, or with your fingernail, as some Lincoln LS owners have suggested. You could also try lubricating the door to see if that helps.
Once you have released the latch and opened the gas tank door, you can then unscrew the gas cap and set it aside. Be sure to place the cap somewhere safe and clean, as you will need to screw it back on once you have finished draining the tank.
With the gas cap removed, you will now have access to the inside of the fuel tank. You can then insert the siphon hose down into the gas tank, attaching the pump to the end of the hose. This will allow you to drain the gasoline from the tank.

Insert the siphon hose into the gas tank
To insert the siphon hose into the gas tank of your Lincoln LS, start by releasing the gas tank latch and opening the gas tank door. Then, unscrew the gas cap and set it aside. Insert the siphon hose into the gas tank in the same way that you would insert the nozzle of a gas pump when filling up your tank at a gas station.
It is important to note that there may be restrictors built into the filler tube for the tank, which could prevent the siphon hose from reaching the gasoline inside the tank. This is an important safety feature designed to prevent gasoline from being easily siphoned out of the tank.
If you are able to insert the siphon hose into the tank, ensure that it reaches the gasoline before proceeding. The siphon hose should be long enough to reach the bottom of the tank, where the gasoline will be. If the hose is too short, you may need to find a longer one or use a different method to drain the gas tank.
Once the siphon hose is properly inserted and has reached the gasoline, you can attach the pump to the end of the hose. This will create a vacuum pressure that will help draw the gasoline out of the tank. In most cases, the pump will be a small, rubber ball-like object that you squeeze to create the necessary vacuum pressure. Alternatively, you may use an electric motor-driven pump for this step.

Attach the pump to the hose and create a vacuum
To attach the pump to the hose and create a vacuum, follow these steps:
First, locate the end of the siphon hose. The siphon hose should already be inserted into the gas tank, with the other end ready to be connected to the pump. The hose should be inserted in the same way that you would insert the nozzle on a gas pump when filling up your tank.
Next, take the pump and attach it to the end of the hose. The pump is typically a small, rubber ball-like object that you can squeeze to create a vacuum and draw out the gasoline. Ensure that the pump is securely attached to the hose to avoid any leaks or disconnections during the draining process.
If you are using an electric motor-driven pump, make sure it is properly connected to a power source before attaching it to the hose. Electric pumps may have specific instructions or requirements for their setup, so refer to the manufacturer's guidelines for proper use.
Once the pump is attached, you can insert the other tubing from the siphon kit into the other end of the pump. This tubing will serve as the outlet for the gasoline being drained from the tank. Ensure that all connections are secure and tight to maintain consistent vacuum pressure and facilitate an efficient draining process.
Finally, you are ready to activate the pump and begin draining the gasoline from your Lincoln LS fuel tank. If you are using a manual pump, gently squeeze the rubber ball to create the necessary vacuum pressure. If you are using an electric pump, turn it on according to the manufacturer's instructions. The pump will create a vacuum, drawing the gasoline out of the tank through the siphon hose and into an appropriate container or receptacle.

Check if the tank is empty by trying to start the car
To check if your Lincoln LS' gas tank is empty, try starting the car. If the car starts and runs smoothly, the tank is not empty. If the car does not start or stalls shortly after starting, the tank is likely empty.
It is important to note that the fuel gauge in your Lincoln LS may not always provide an accurate reading of the fuel level. There are several reasons why the fuel gauge may indicate an empty tank even when there is still fuel in the tank:
- A faulty fuel level sending unit: The fuel level sending unit is responsible for reporting the fuel level to the gauge in the dashboard. If this unit is faulty, the gauge may not accurately reflect the actual fuel level.
- A bad wire, ground, or module: Electrical issues such as a bad wire, ground, or module can cause the fuel gauge to malfunction and display incorrect information.
- Fuel siphoning or theft: If someone has siphoned or stolen fuel from your tank, the gauge may indicate an empty tank even if there is still some fuel remaining.
To confirm if the tank is truly empty, you can try adding a small amount of fuel and observing if the gauge updates accordingly. If the gauge remains unchanged, it is likely that the sensor or fuel level sending unit is faulty.
Additionally, it is worth noting that the definition of an "empty" gas tank can vary. Some car owners consider a tank empty when the pump clunks off before filling the tank to its specified capacity. In this case, there may still be some fuel remaining in the tank.
To ensure that your Lincoln LS' gas tank is completely empty, you may need to take additional steps such as running the car until it runs out of fuel or siphoning the remaining fuel from the tank. However, it is important to exercise caution when handling fuel and refer to the owner's manual or seek professional assistance if needed.

If the car starts, let it run until it stalls
If your Lincoln LS starts after attempting to drain the fuel tank, let the car run until it stalls. This is because there may be a small amount of gasoline that the siphon and pump were not able to remove. By letting the car run, you ensure that any remaining gasoline is used up, and your fuel tank is completely drained.
It is important to note that a car stalling can be indicative of other issues with your vehicle. For example, a Lincoln LS may stall due to a faulty idle air control actuator, which controls the engine RPMs when idling. A clogged or restricted EGR valve can also cause stalling, as well as loose or corroded wires in the wiring harness, which can result in inconsistent ignition and quick voltage loss. If your car consistently stalls, it is recommended to consult a mechanic for an inspection to identify and address any underlying issues.
Additionally, some Lincoln LS owners have reported issues with their vehicles stalling or struggling to start, particularly in cold weather. In some cases, this may be due to problems with the battery or fuel pump, which may require replacement or repair. It is always advisable to consult a professional mechanic if you are unsure about the cause of your car's stalling or if you are uncomfortable performing any repairs yourself.
Remember, safety should be a top priority when working on your vehicle. Ensure that you are in a well-ventilated area when dealing with gasoline, and take the necessary precautions to avoid any accidents or injuries.
