Replacing Your 2009 F150 Fuel Lid Door: Easy Steps

If you're looking to replace the fuel lid door on your 2009 F150, you've come to the right place. This is a relatively easy and cheap fix that you can do yourself in under 20 minutes. The first step is to remove your fuel cap and set it aside. Then, using a 7mm socket driver, remove the screws holding the fuel tank filler neck to the housing. Next, you'll need to remove the fuel door cap by gently prying it off with a small flat-head screwdriver. Be careful not to damage the plastic hinge. With the cap removed, you can now detach the housing from the body of the truck by locating and popping out the two notches that hold it in place. Simply rotate the housing, and it should come right out. Transfer your fuel cap to the new housing by snapping it into place, and then install the new housing into the body of the truck, making sure to line up the notch. Finally, secure the housing with the screws, and you're done!

Remove fuel cap and tape off the opening to the filler neck

To remove the fuel cap and tape off the opening to the filler neck of your 2009 F-150, follow these steps:

Park your vehicle on a flat, hard surface and ensure the transmission is in park (for automatics) or in 1st gear (for manuals). Engage the parking brake to lock the rear tires from moving.

Open the fuel door to access the fuel filler neck. Remove the mounting screws or bolts attached to the cutaway.

Remove the fuel filler cap cable from the fuel neck and set it aside.

Now, you'll need to tape off the opening. Painter's tape is a good option as it won't damage the paintwork. Carefully apply the tape around the opening to the filler neck, making sure to cover it completely. This will protect the opening and the surrounding area while you work on the rest of the repair.

With the fuel cap removed and the opening taped off, you can continue with the rest of the fuel lid door replacement process.

Please note that this is a general guide and you may need to refer to a specific repair manual for your 2009 F-150 or seek the assistance of a qualified mechanic to ensure a safe and proper repair.

Remove the three screws holding the fuel tank filler neck to the housing

To remove the three screws holding the fuel tank filler neck to the housing, you will need a 7mm six-point socket with a long extension (1/4" drive is safest) or a socket wrench screwdriver.

First, remove your fuel cap and hang it to one side. Then, with your 7mm socket, remove the three bolts holding the fuel tank filler neck to the housing. Spraying the screws with a little silicone grease will help to prevent them from chipping anything when they are removed.

Now, take a small flat-head screwdriver and stick it into the little hole on the housing where the fuel door is attached. Push the screwdriver towards the fuel door and then gently pull the screwdriver back towards yourself. The door will begin to separate from the housing and will pop up slightly. You can then pull the door gently towards you and remove it.

You can now lift the housing out of the body of the truck.

Remove the fuel door cap

To remove the fuel door cap from your 2009 F150, first, you must remove your fuel cap and hang it to the side. Then, with a 7mm socket, remove the three bolts holding the fuel tank filler neck to the housing.

Now, to remove the fuel door cap, insert a small flat-head screwdriver into the little slot between the door and the plastic hinge. Push the screwdriver towards the door cap and slowly, gently, pull it towards yourself and it will slide forward. Then, gently pull it off.

To reinstall the fuel door cap, simply reverse the removal process. Slip the cap on, move it back towards the truck, and click it into place.

Remove the housing assembly

To remove the housing assembly, you will need a 7mm six-point socket with a long extension (a 1/4" drive is safest) or a socket wrench screwdriver, two small flat-head screwdrivers, and a replacement fuel door housing assembly. You may also want to use a work light and some gloves.

First, remove your fuel cap and hang it to one side. Then, use your 7mm socket to remove the three bolts holding the fuel tank filler neck to the housing.

Next, remove your fuel door cap. Insert a small flat-head screwdriver into the little slot between the door and the plastic hinge. Push the screwdriver towards the door cap and slowly, gently, pull it towards yourself and it will slide forward. Then, gently pull it off.

Now, find the two slots on the top of the housing and insert your two small screwdrivers into them firmly so they stick in. Lift up on the screwdrivers with one hand and pull the housing assembly towards you. The east end of the housing, facing the rear end of the truck, needs to come out first. Remove it in a curve motion as the housing cubby hole is a large square shape.

Finally, remove the fuel cap from the old hinge by pulling on the cord at a 45-degree angle.

Re-install the fuel cap on the new hinge

To reinstall the fuel cap on the new hinge, first, pull the fuel cap off the old hinge by pulling it at a 45-degree angle. Then, attach the fuel cap to the new hinge by snapping it into place.

To do this, place the cap onto the hinge and apply pressure until you hear a snap. This indicates that the cap is securely in place.

It is important to ensure that the cap is correctly installed onto the hinge to avoid any issues when opening and closing the fuel door.
