What You'll Learn
Locating the suspension switch
To locate the suspension switch on a 2000 Lincoln Town Car, open the trunk of the car and look on the left side. You should see a switch that you can turn to the "off" position. Once you have located and turned off the suspension switch, you can jack the car up from the rear and drain the gas out of the tank.
To replace the fuel pump, you will need to disconnect any lines running into the cap and remove the cap itself. You may need a hammer and a screwdriver to do this. As you pull the cap off, pull it straight up and out, and you may need to turn the assembly to an angle as the fuel sending unit is attached to it. The fuel pump and sending unit are attached together on the assembly that is submerged in the tank.
Once you have removed the old fuel pump, you can install the new one. Place the new o-ring along the threaded part of the tank, where the old one was, and then place the cap over the flat part of the fuel pump assembly. Make sure the cap is tight and secure the lines back onto the fuel pump. There will be two electrical lines and two small hoses that attach to the top. Start lifting the tank into place and put the bands back into place.
Remember to replace the o-rings with new ones and wash your tank out to remove any sediment inside. You can use excess fuel or water to do this, but if you use water, make sure the tank is completely dry before reinstalling it.

Draining the gas tank
To begin, locate the suspension switch in the trunk of the car on the left side. Turn this switch to the "off" position. It is important to note that jacking up the vehicle with the suspension on is not recommended as it may cause tears in the air bags. Instead, jack the car up from the rear to gain access to the gas tank.
Once the car is securely jacked up, you can start the process of draining the gas tank. Look for a plug from which to drain the fuel. Using a ratchet, unscrew the four bolts from the bands. As you unscrew these bolts, the gas tank will start to drop. It is important to place another jack or a tall cinder block under the tank to support it and prevent it from falling.
With the tank now accessible, you can proceed to disconnect any lines running into the cap. This may require the use of a hammer and a screwdriver to loosen and remove the cap. As you pull the cap off, pull it straight up and out. You might need to turn the assembly to an angle as you remove it, as the fuel sending unit is attached to it. The fuel pump will become visible as you pull up the cap.
At this point, you can drain the remaining fuel from the tank. Remember to replace the o-rings with new ones and wash the tank to remove any sediment. You can use excess fuel or water for this step, but ensure the tank is completely dry before reinstalling it. Once the tank is cleaned, you can start reassembling the components.

Disconnecting the lines to the cap is a crucial step in replacing the fuel pump of a 2000 Lincoln Town Car. To begin, lay the tank on the ground and identify all the lines running into the cap. These lines include two electrical lines and two small hoses. Using a screwdriver and possibly a hammer, carefully unscrew the cap, pulling it straight up and out. As you remove the cap, you may need to angle the assembly due to the attached fuel sending unit. The fuel pump will become visible as you lift the cap, and you will notice that it is connected to the sending unit within the assembly submerged in the tank. Ensure you detach the cap from the rest of the fuel pump before proceeding.
