Replacing The Fuel Pump In Your 2005 Lincoln Town Car

The fuel pump in a 2005 Lincoln Town Car is located inside the fuel tank and can be replaced by carefully following a series of steps. The process involves locating and turning off the suspension switch, jacking up the car, draining the gas tank, unscrewing bolts, detaching fuel lines, and replacing the fuel pump and related components. It is important to exercise caution when working with fuel and ensure that all parts are securely connected before starting the car. The average cost for this replacement ranges from $611 to $1,181, depending on the vehicle's age and location.

How to Replace a Fuel Pump on a 2005 Lincoln Town Car

Disconnect the battery

To disconnect the battery of your 2005 Lincoln Town Car, locate the suspension switch in the trunk of the car on the left side. Turn the switch to the "off" position. It is important to do this before jacking up the vehicle, as failing to do so may cause tears in your air bags.

Disconnecting the battery is the first step when replacing the fuel pump, in order to reduce the chance of a fire.

After disconnecting the battery, you can proceed with the next steps to replace the fuel pump. This includes jacking up the car from the rear and draining the gas out of the tank. You will then need to unscrew the four bolts from the bands, place another jack or a tall cinder block to hold the tank, and pivot the tank back and forth to assist in lowering it.

Remove the access cover

To remove the access cover of your 2005 Lincoln Town Car's fuel pump, you'll first need to disconnect the battery to reduce the chance of a fire. Next, locate the suspension switch in the trunk of the car on the left side and turn it to the "off" position.

Now, jack up the car from the rear and drain the gas from the tank. You should see a plug from which to drain the fuel. Using a ratchet, unscrew the four bolts from the bands. As you do this, the gas tank will start to drop, so place another jack or a tall cinder block beneath it to support it.

With the tank supported, you'll need to pivot the tank back and forth to assist it down. Once it's down, place it on a stand (jack or cinder block). Now you can undo the fuel inlet line as it connects to the top of the tank. It is held on by a hose clamp, so unscrew this from the tank and the line will slide off.

Now, lay the tank on the ground and disconnect any lines running into the cap. You may need a hammer and a screwdriver to do this. Pull the cap straight up and out, turning the assembly at an angle as you do so since the fuel sending unit is attached.

The fuel pump is now visible, and you can begin to remove it. Remember to replace the o-rings with new ones when you're putting the new pump in.

Drain the fuel tank

To drain the fuel tank of a 2005 Lincoln Town Car, you have a few options. Firstly, you could use a fuel siphon system, which can be purchased at most auto stores. This involves feeding a hose into the gas tank and pumping the fuel out into a container. However, newer cars may have protective metal bulbs or screens that prevent gas from escaping, so you may need to use a smaller, rigid tube to force down and twist around the metal bulb, before feeding the larger tube over the top and pumping the fuel out.

Another option is to drain the tank directly. Place a pan or receptacle underneath the drainage plug, which is a small bolt screwed into the tank. Then, simply unscrew the drainage plug and let the fuel drain out. This can take several minutes per gallon, so be prepared with enough containers to catch the fuel.

If your car has a fuel test port under the hood, you can drain the fuel by jumping the fuel pump relay or using a scan tool to turn on the fuel pump while the engine is not running.

Finally, if your car has fuel lines (small, removable hoses underneath the tank), you can turn the car on and off repeatedly to force the gas out of the tank using the electric fuel pump.

Remember to take all necessary precautions when working with fuel, including having a fire extinguisher nearby.

Remove the fuel inlet line

To remove the fuel inlet line on a 2005 Lincoln Town Car, you will need to first locate the suspension switch in the trunk of the car on the left side. Turn the switch to the "off" position. Do not jack the vehicle up with the suspension on, as this may damage the air bags. Next, jack up the car from the rear and drain the gas from the tank. You will see a plug from which to drain the fuel.

Using a ratchet, unscrew the four bolts from the bands. As you do this, the gas tank will start to drop. Place a jack or a tall cinder block under the tank to support it as you lower it. The tank is oblong-shaped, so you will need to pivot it back and forth to remove it. Once the tank is lowered, place it on a stand.

Now you can remove the fuel inlet line. It connects to the top portion of the tank and is held on by a hose clamp. Unscrew the hose clamp from the tank and slide the line off. Lay the tank on the ground and disconnect any lines running into the cap. You may need a hammer and screwdriver to do this. Pull the cap straight up and out, turning the assembly at an angle as you do so, as the fuel sending unit is attached.

This process is not without its risks. Working with fuel can be dangerous, so exercise caution when working with open gasoline. It can irritate the skin and is extremely flammable.

Wash the tank

To wash the tank of your 2005 Lincoln Town Car, you can use the excess fuel or water. If you use water, ensure that the tank is dried out completely before re-installing it.

• Locate the suspension switch in the trunk of the car on the left side. Turn that switch to the "off" position.
• Jack the car up from the rear and drain the gas out of the tank.
• Unscrew the four bolts from the bands using a ratchet. As you are unscrewing these bolts, the gas tank will start to drop.
• Place another jack or a tall cinder block to hold the tank up while you are dropping it.
• Pivot the tank back and forth to assist in lowering it. As it comes down, place it on the stand (jack or cinder block).
• Disconnect the fuel inlet line by unscrewing the hose clamp from the tank.
• Lay the tank on the ground and disconnect any lines running into the cap.

Once the tank is cleaned out, you can start putting it back together.
