What You'll Learn
Replacing the pump and pre-pump filter screen
To replace the pump and pre-pump filter screen of a 2006 Ford Expedition, you will first need to disconnect the battery to reduce the chance of a fire. Then, if the pump is inside the fuel tank, you will need to remove the access cover. In some cases, you will need to drain the fuel before removing the access panel. Once the cover is off, the pump can be replaced, and the fuel lines disconnected. The old pump can then be removed and a new one installed. Once the new pump is in place, the fuel lines can be reconnected, and the access panel replaced. Finally, a check should be done to ensure there are no fuel leaks and that the problem has been solved.
If the pump is not receiving enough voltage or has a bad connection, the circuit may need to be replaced. If the pump is working but providing low pressure or too little fuel, the mechanic will check the fuel filter, as well as the electrical and mechanical condition of the fuel pump itself.
You can also purchase a replacement fuel pump hanger assembly from Bosch, which meets strict Ford Motor Company standards. You can also repair the fuel pump relay if that is the issue.

Disconnecting the battery
To disconnect the battery, first locate the battery in the engine bay. It is usually located near the front of the vehicle, on the driver's side. Once you have located the battery, you will need to identify the negative (-) and positive (+) terminals. The negative terminal is usually marked with a "-" symbol, and the positive terminal with a "+" symbol.
Using a wrench or socket, loosen the nut that secures the negative battery cable to the negative terminal. Do not allow the wrench to touch any metal parts of the vehicle, as this could cause a spark and potentially start a fire. Once the nut is loose, carefully remove the cable from the terminal.
Repeat this process for the positive battery cable, ensuring that you do not allow the wrench to touch any metal parts of the vehicle. With both cables disconnected, the battery is now safely disconnected.
It is important to note that disconnecting the battery will reset the vehicle's computer, which may cause the check engine light to come on. This is normal and should not be a cause for concern.

Removing the access cover
If your fuel pump is inside the fuel tank, you will need to remove the access cover. Before doing so, you should disconnect the battery to reduce the chance of a fire. In some cases, you will also need to drain the fuel before removing the access panel. Once the cover is off, the technician can replace the pump and pre-pump filter screen.
To remove the access cover, you will need to locate it first. It is usually found on the top or side of the fuel tank. Once you have located the cover, you will need to remove any screws or bolts that are holding it in place. Be careful not to drop them into the fuel tank.
If the screws or bolts are rusted or difficult to remove, you may need to use a penetrating oil or lubricant to help loosen them. Once you have removed all the screws or bolts, you can carefully lift off the access cover. Again, be careful not to drop it into the fuel tank.
With the access cover removed, you will now have access to the fuel pump. You can then proceed to replace the pump and pre-pump filter screen. Remember to install a new gasket or seal when replacing the access cover to prevent any fuel leaks.
