Changing Your F150: Replacing The Fuel Filter

The 2009 Ford F-150 is equipped with a lifetime fuel filter that is integrated with the fuel tank, according to the owner's manual. This means that regular maintenance or replacement is not needed. However, some people have expressed doubt over the effectiveness of this internal fuel filter, and some models do seem to have an external fuel filter. This external fuel filter is located on the inside of the frame, under the driver's door.

The fuel filter is in the fuel tank with the pump

If your 2009 F150 has a fuel filter in the fuel tank with the pump, it is a lifetime fuel filter that doesn't require regular maintenance or replacement. This is according to the owner's manual.

However, some people have added an external fuel filter to their 2009 F150. If you want to do this, you can buy a fuel filter on Amazon for about $13. You will also need to buy a plastic or metal fuel line release tool. You can get this at any auto store.

To change the fuel filter, stick a screwdriver into the fuel fill to release pressure first. Then, use the tool to release the fuel lines. Remember to follow the flow direction when putting in the new filter.

The filter is not meant to be serviced

The 2009 F150 fuel filter is not meant to be serviced. It is a lifetime fuel filter integrated with the fuel tank, and regular maintenance or replacement is not needed. This means that the filter is designed to last the lifetime of the vehicle, and you should not need to replace it.

However, if you are experiencing poor fuel economy or slow acceleration, it could be a sign that your fuel filter needs to be replaced. A dirty filter can cause problems with your injectors, which can make your vehicle work harder than usual. If you suspect that you have filled up with a batch of questionable fuel, it is recommended that you change your filter immediately.

Changing your fuel filter is a relatively simple task that can be performed by a novice. However, it is important to note that it is a maintenance routine that should be performed with the engine running. Remember to relieve the pressure from the fuel system before beginning any work. This can be done by removing the fuse cover located under the hood on the driver's side and tripping the inertia fuel reset switch, which should have a red rubber top. You should also have towels handy, as fuel tends to gush out during this process.

Once the pressure has been relieved, you can locate and remove the fuel filter. It is usually located on the driver's side of the frame rail, under the driver's side door. To remove it, unhook the metal retaining clip and use a line compression removal tool to slide the lines off the filter. Then, use a flat-blade screwdriver to disconnect the dirty filter. When installing the new filter, ensure that the flow arrow is pointing towards the front end of your F150.

You can relieve fuel pressure by sticking a screwdriver into the fuel fill

When changing the fuel filter on a 2009 F-150, it is important to relieve the fuel pressure before disconnecting the fuel lines. One way to do this is by sticking a screwdriver into the fuel fill. This method is not recommended by some mechanics, who suggest alternative methods such as removing the fuel pump fuse and cranking the engine, or relieving the pressure with the test-port valve. However, sticking a screwdriver into the fuel fill to release pressure is a quick and effective method, as demonstrated by a user on the Ford Truck Enthusiasts Forum.

To begin, locate the fuel fill. This is usually found on the left frame rail, approximately 3 feet from the tank. Before attempting to relieve the pressure, it is important to take safety precautions. Wear protective gear, such as gloves and eye protection, to shield yourself from any potential fuel spray. Ensure the area is well-ventilated to prevent the buildup of flammable fumes.

Once you have located the fuel fill and taken the necessary safety measures, you can proceed to relieve the fuel pressure. Place a shop rag or a heavy cloth around the fuel fill to catch any escaping fuel. Then, carefully insert a screwdriver into the fuel fill. Gently push the screwdriver in to depressurize the system. You may feel some resistance, but do not force the screwdriver too hard as this may cause damage.

As you depress the screwdriver, fuel may begin to pour out of the fuel fill. Continue to apply pressure until the fuel stops flowing. Once the fuel flow has ceased, carefully remove the screwdriver and replace the fuel fill cap. It is important to ensure that the cap is securely tightened to prevent any leaks.

By following these steps, you can safely and effectively relieve the fuel pressure in your 2009 F-150 by sticking a screwdriver into the fuel fill. This will allow you to proceed with changing the fuel filter or performing other maintenance tasks. Remember always to exercise caution when working with fuel systems to avoid injury and damage.

The filter is located under the driver's side door

To change the fuel filter on your 2009 F-150, you'll first need to locate it. The fuel filter is situated under the driver's side door, on the inside frame rail, near the rear of the transfer case.

Now, let's go through the process of changing the fuel filter, with a specific focus on the filter's location under the driver's side door.

Step 1: Relieve the pressure from the fuel system

Start by removing the fuse cover, which is located under the hood on the driver's side. Then, trip the inertia fuel reset switch, which should have a red rubber top. This is one of the few maintenance steps you'll perform with the engine running. Disable the switch by tapping it in the middle with a rubber mallet. You'll know you've succeeded when the motor stops.

Step 2: Remove the fuel filter

Now, we'll focus on the section of your F-150 that is just under the driver's side door. Here, you'll find the fuel filter. To remove it, first unhook the metal retaining clip. Then, position the line compression removal tool at the front end of the filter and apply a small amount of pressure, sliding the tool into the line fitting until it slides off. Keep some towels handy, as fuel tends to spill during this step. Repeat this process at the rear of the filter, applying minimal pressure. Once both ends of the line fitting are removed, use a flat-blade screwdriver to disconnect the dirty filter.

Step 3: Replace the filter

Install a new filter, ensuring that the flow arrow is pointing towards the front end of your F-150. Reconnect the front line and hook the retaining clip back into place. Repeat this process for the rear line.

Step 4: Reset and test

With the new filter in place, reset the inertia switch by clicking the red button. Cycle the ignition a few times before checking for leaks, and remember to keep the engine running when testing.

There you have it! You've successfully located and replaced the fuel filter under the driver's side door of your 2009 F-150.
