How To Change Fuel Filter In 06 F350

Changing the fuel filter on a 2006 F350 is a simple task that can be completed in about 30 minutes. The fuel filter should be changed regularly, at least twice a year or every 10,000 miles, to ensure the health of the fuel system and improve the performance of the vehicle. This maintenance task can save you money in the long run and prevent potential issues with the fuel injectors.

The primary fuel filter is located under the driver's side door, on the frame rail

The primary fuel filter on a 2005 F-250, or any other ’03 - ’07 Ford 6.0L Powerstroke engine in Excursions or F250 - F550 trucks, is located under the driver's side door, on the frame rail. This is the long steel rail that runs the length of the truck.

To change the primary fuel filter, you will need to place a tub or bucket beneath the fuel pump, which is located under the driver's side door on the frame rail. You will then need to locate the allen plug on the side of the fuel pump. This is a small, brass plug. Using a 6mm allen wrench, remove the allen plug. With the catch bucket directly in place, drain the fuel and water completely.

Next, using a 36mm socket, remove the large black end cap on the end that’s nearer to the engine. The fuel filter will slide out along with the cap. Pull the old filter and the o-ring from the cap, and properly dispose of both. After draining the filter for a full 24 hours, you can place it in a lidded coffee can or leak-proof plastic bag to safely take it to a recycling centre that accepts scrap metal.

Now, install the new primary fuel filter into the cap. Once seated properly in the cap, the new filter will snap into place. Install the supplied o-ring into position on the end cap. Insert the new filter and cap section into the fuel pump, using the 36mm socket to tighten the cap securely—torque to 19lb. per ft. Being mindful not to over-tighten or cross-thread it, reinstall the allen plug.

Finally, remember to prime the fuel system and bleed out any air. To do that, turn the ignition to the Run position three separate times—for 30 seconds each time.

The secondary filter is located on the engine, between the CAC tube and the air intake tube

The secondary fuel filter on a 6.0L Powerstroke engine is located on the engine, between the CAC tube and the air intake tube. This is the smaller of the two lids that are designed to keep any extra crap from clogging the filters.

To replace the secondary fuel filter, follow these steps:

Step 1: Remove the black top cap

Using a 24mm socket or 1/2" square drive ratchet, remove the black top cap.

Step 2: Remove the fuel filter and o-ring

Remove the fuel filter from the housing and the o-ring from the lid.

Step 3: Drain excess fuel

Using a turkey baster, drain the excess fuel from the housing. Remember to dispose of the fuel properly.

Step 4: Insert the new secondary filter

Insert the new secondary filter into the housing.

Step 5: Install the new o-ring

Install the new o-ring onto the lid.

Step 6: Reinstall the black top cap

Reinstall the black top cap, using the 24mm socket or 1/2" square drive ratchet to torque the bolt to 124lb. per in. (or approximately 10 – 11lb. per ft.).

After replacing the secondary fuel filter, it is important to prime the fuel system and bleed out any air. To do this, turn the ignition to the Run position three separate times for 30 seconds each time. Failing to properly prime the fuel system can cause serious damage to the injectors.

You will need a fuel filter kit, a bucket or tub for draining the fuel, and a leak-proof container for transporting the old filter for disposal

To change the fuel filter on your 2006 F350, you will need a fuel filter kit, a bucket or tub for draining the fuel, and a leak-proof container for transporting the old filter for disposal.

You can order a fuel filter kit online or purchase one from an auto parts store. Make sure to get the correct kit for your truck's make and model. The fuel filter kit will come with the necessary filters and O-rings for your truck.

You will also need a bucket or tub to catch the drained fuel and a leak-proof container to transport the old filter for disposal. You can use a coffee can or any other leak-proof container for disposal. It is important to properly dispose of the old filter and any drained fuel.

In addition to the above, you will need some specific tools to change the fuel filter on your 2006 F350. These tools include a 36mm socket, a 6mm Allen wrench, and a 24mm socket or 1/2" drive ratchet.

With these tools and supplies, you can change the fuel filter on your 2006 F350. Remember to place the bucket or tub under the fuel pump before starting and to properly dispose of any drained fuel and old filters.

The correct size socket for the fuel filter cap is 36mm

To change the fuel filter on a 2006 F350, you will need a 36mm socket. This socket size is suitable for both the primary and secondary fuel filters. The primary fuel filter is located under the driver's side door, on the frame rail. The secondary filter is located in the engine, sitting between the CAC tube and the air intake tube.

The 36mm socket is used to remove the large black end cap of the fuel filter. It's important to place a tub or bucket beneath the fuel pump to catch any fuel or water that may spill out during the removal process. Once the cap is removed, pull out the old filter and the o-ring, disposing of them properly.

It is recommended to use only Motorcraft fuel filters or Racor replacement fuel filters. After installing the new primary fuel filter into the cap, insert the new o-ring into position and tighten the cap securely using the 36mm socket.

In addition to the 36mm socket, other tools required for this task include a 6mm Allen wrench, a 24mm socket or 1/2" drive ratchet, and a bucket or tub for draining the fuel.

After replacing the filters, you must prime the fuel system and bleed out any air by turning the ignition to the Run position three times for 30 seconds each

After replacing the fuel filters, you must prime the fuel system and bleed out any air. This is a critical step and must not be skipped, as failing to do so can cause serious damage to the injectors. To prime the fuel system, get into the cab and turn the ignition key to the 'Run' position. This is the position just before cranking the starter. Leave the key in this position for 30 seconds, then turn it off. Repeat this process three times.

It is important to note that the engine should not be started until this process is complete. If the engine is started without priming the fuel system, there is a risk of damaging the injectors. This damage may not be immediately apparent or detectable, as the injectors can continue to run normally for a short time.

Priming the fuel system is a simple but essential step in the process of replacing fuel filters. It helps ensure the proper functioning of the fuel system and prevents potential damage to the injectors.
