Replacing Your 2010 Ford F150 Fuel Filter: Step-By-Step Guide

The fuel filter in your 2010 Ford F150 is located on the fuel pump and does not need to be changed unless the fuel pump is being replaced. However, if you are experiencing poor fuel economy or slow acceleration, you may need to replace the fuel filter. This can be done by relieving the pressure from the fuel system, removing the fuel filter, replacing it with a new one, and resetting and testing the new filter.

Relieve the pressure from the fuel system

To relieve the pressure from the fuel system of your 2010 Ford F-150, 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 routines you should perform with your engine running. Disable the switch by tapping it in the middle with a rubber mallet. You will know you have been successful when the motor gives out.

It is important to note that you should never perform this task with a hot engine. Always use eye protection and do not smoke while performing maintenance on a fuel system. Additionally, make sure to release the fuel pressure in the fuel line, as gas will spray everywhere if you do not. On the passenger's side fuel rail (on the engine), there is a Schrader valve that you can depress to depressurize the lines.

Remove the fuel filter

To remove the fuel filter from your 2010 Ford F-150, first relieve the pressure from the fuel system. Begin by removing the fuse cover located under the hood on the driver's side. Then, trip the inertia fuel reset switch, which should have a red rubber top. You should be able to disable the switch by tapping it in the middle with the end of a rubber mallet.

Next, locate the fuel filter. It is situated just under the driver's side door. 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 out during this step. Repeat this process at the rear of the filter, applying minimal pressure. Once both ends of the line fitting have been removed, use a flat-blade screwdriver to disconnect the dirty filter.

Now, you can install the new filter. Ensure that the flow arrow on the new filter is pointing towards the front end of your F-150.

Replace the filter

Before starting, ensure you have the right tools for the job: a medium flathead screwdriver and a 5/16 line compression removal tool. It is also important to prioritise safety. Always use eye protection, and do not smoke while performing maintenance on a fuel system. It is also recommended to NEVER perform this task with a hot engine.

Now, you can begin by relieving the pressure from the fuel system. Start 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 be able to disable the switch by tapping it in the middle with the end of a rubber mallet. You will know you have been successful when the motor gives out.

Next, locate the fuel filter. It is positioned in the line leading from the gas tank to the engine. For most vehicles, it is located inside the top of the fuel tank, where it connects with the fuel line. On some cars, it might be elsewhere along the fuel line.

To remove the old filter, unhook the metal retaining clip and position the line compression removal tool so that it rests on the front end of the filter. Apply a small amount of pressure, sliding the tool into the line fitting until it slides off. Keep towels handy, as fuel tends to gush out during this step. Repeat this process at the rear of the filter, applying as little pressure as possible. Once both ends of the line fitting have been removed, use the flat blade screwdriver to disconnect the dirty filter.

Now, you can replace the worn filter with a new one, being careful to position it so that the flow arrow is pointing towards the front end of your F-150. Once the new filter is in place, reconnect the front line and hook the retaining clip back into position. Repeat this process for the rear line.

With the new filter in place, you are free to reset the inertia switch by clicking the red button once more. Cycle the ignition a few times before checking for leakage and remember to keep the engine running when testing out your new filter.

Reset and test

Now that you have installed the new fuel filter, you can reset the fuel pump inertia by pressing the red switch until it clicks.

Turn the ignition on, but don't start the engine. Count to 10, then turn it off. Repeat this process about three to four times.

Check for leaks by turning on the ignition and inspecting the fuel line and the area around the filter. If there are no leaks, you're good to go!

Start the engine. It may run a little rough at first as the fuel line clears out the air, but it should smooth out after a few seconds. Check for leaks one final time with the engine running.

Close the fuse panel, and you're done! You've successfully replaced your Ford F-150 fuel filter and saved yourself some money.

Safety precautions

Safety should be a top priority when performing any maintenance on your vehicle. Here are some detailed safety precautions to follow when replacing the fuel filter on your 2010 Ford F150:

Work in a Well-Ventilated Area

It is important to ensure that you are working in a well-ventilated area when replacing your fuel filter. Fumes from gasoline can be dangerous, and proper ventilation will help reduce the risk of inhaling these fumes. Choose an outdoor workspace or a well-ventilated garage to perform the replacement.

Wear Personal Protective Equipment (PPE)

Before starting the replacement, put on safety goggles to protect your eyes from any debris or gasoline splashes. You should also wear gloves to protect your hands from dirt, grease, and gasoline. Additionally, consider wearing a long-sleeved shirt and pants to avoid any skin exposure to gasoline and sharp edges.

Relieve Pressure from the Fuel System

This step is crucial for safety. Locate the fuse cover under the hood on the driver's side, and remove it. Find the inertia fuel reset switch with a red rubber top and disable it by tapping it with a rubber mallet. This will stop the engine and relieve the pressure from the fuel system.

Contain Fuel Spillage

Fuel tends to gush out when removing the fuel filter. Have several towels or rags handy to absorb the fuel spillage and prevent it from spreading. You can also place a drip pan or a large piece of cardboard underneath the filter to catch the fuel.

Prevent Fire Hazards

Gasoline is highly flammable, so it is essential to take precautions to prevent fire hazards. Do not smoke or have any open flames nearby during the replacement process. Keep a fire extinguisher nearby in case of any accidents. Ensure that the engine is cool before starting the replacement, and avoid any hot surfaces that may ignite spilled fuel.

Disconnect the Battery

Before beginning any work on your vehicle's fuel system, it is important to disconnect the battery. This will prevent any accidental electrical shorts that could cause a fire or damage to the vehicle's electrical system. Disconnect the negative terminal first, followed by the positive terminal.

Properly Dispose of the Old Fuel Filter

Once you have removed the old fuel filter, do not dispose of it in your regular trash. The old filter will contain gasoline residue, which can pose a fire hazard and environmental risk. Contact your local waste management authority or auto parts store to inquire about proper disposal methods and locations.

Be Aware of Sharp Edges

When working around the fuel tank and fuel lines, be cautious of sharp edges that could cause cuts or injuries. Take your time and work carefully to avoid any accidental cuts. Wear gloves to protect your hands, and cover any sharp edges with tape or a cloth if necessary.

Do Not Over-Tighten Connections

When installing the new fuel filter, be careful not to over-tighten the connections. Over-tightening can damage the fuel lines, the filter, or the fittings. Hand-tightening the connections is generally sufficient, but you can use tools if necessary, being careful not to apply excessive force.

Re-connect the Battery and Check for Leaks

After installing the new fuel filter, re-connect the battery by first attaching the positive terminal, then the negative terminal. With the engine off, check the fuel filter and fuel lines for any signs of leaks. If there are no leaks, start the engine and check again. Ensure that all connections are secure and that there are no fuel odors.

Seek Professional Help if Needed

If you feel uncomfortable or unsure about performing the fuel filter replacement, it is always best to seek professional help. A qualified mechanic will have the experience and knowledge to safely and correctly replace the fuel filter on your 2010 Ford F150.
