What You'll Learn
Removing the skid plate and filler hose
To remove the skid plate and filler hose on your F350, you will need to follow a few careful steps to ensure you do not damage any parts. Firstly, it is important to gather the necessary tools and materials. These include a fuel line removal tool, which can be purchased or ordered online, and some sort of lubricant or rust remover like Aero-Kroil or PB Blaster.
Once you have the tools, start by spraying the tank hanger bolts and nuts with your chosen lubricant. This will help to free up any rust or debris that has built up over time. Next, you will need to remove the bolts holding the gas cap neck in place. Depending on your model, you may need a 13mm box wrench and a 15mm deep socket to remove the bolts and nuts. With the gas cap neck removed, you can now access the fuel lines and the skid plate.
To remove the fuel lines, look for the plastic buttons or tabs on the lines. These need to be pushed in, and then you can pull the lines off. Be careful not to damage the lines, as you may need to replace them if they break. Additionally, pay attention to any check valves or inline components on the fuel lines, as these can make removal more challenging. If you encounter any issues, try using a smaller removal tool or twisting the line back and forth to break up debris and rust.
With the fuel lines removed, you can now focus on the skid plate. The skid plate is located beneath the front axle and may require lowering the gas tank to access it fully. Once you have reached the skid plate, you can begin the process of removing it. This may involve unscrewing or unbolting any attachments holding the skid plate in place. Refer to your specific model's manual for detailed instructions on skid plate removal, as the process may vary slightly between different F350 models.

Using a screwdriver to undo clips
Removing the fuel lines from your F350's gas tank can be a tricky process, and it's important to take great care to avoid damaging any components. One key step in this process is using a screwdriver to undo the clips that secure the fuel lines in place. Here's a detailed guide on how to do this:
Locate the Clips: Begin by identifying the clips that hold the fuel lines in place. These are typically located at the connection points between the fuel lines and the gas tank. For some F350 models, you may find internal plastic retaining clips inside the 90-degree fittings connected to the tank's sending unit or fuel pickup assembly.
Depress the "Magic" Button: Before attempting to remove any clips, it's crucial to locate and depress the "magic" button, usually indicated by a yellow arrow. This button locks the connection, and failing to depress it may result in breaking the clip or damaging other components. Use a flat-blade screwdriver to gently press this button. It doesn't require much force.
Position the Screwdriver: While continuing to depress the "magic" button with one screwdriver, take a second flat-blade screwdriver, preferably one with a wider blade, and carefully insert it into the space between the clip and the filter. Positioning the screwdriver here will provide leverage for the next step.
Rotate the Screwdriver: With the second screwdriver in position, gently rotate it. This action will apply pressure to the clip, pushing it to the side and past its engagement point. Be cautious not to use excessive force, as this may damage the clip or surrounding parts.
Slide Off the Clip: Once you've rotated the screwdriver and disengaged the clip, you should be able to set down the screwdrivers and use your hands to gently slide the clip off the rest of the way. Take care not to yank or pull forcefully, as this can lead to breakage.
By following these steps, you can effectively use a screwdriver to undo the clips securing the fuel lines to your F350's gas tank. Remember to work carefully and deliberately to avoid any accidental damage to the fuel system.

Using a fuel line removal tool
Removing fuel lines from a gas tank can be a challenging task, but with the right tools and techniques, it can be accomplished successfully. Here is a step-by-step guide on using a fuel line removal tool to detach the fuel lines from your F350:
Before beginning, ensure you have the appropriate fuel line removal tool. Both plastic and metal tools are available, and some sources recommend the cheaper plastic tools over the metal ones. These tools are typically available at auto parts stores or online. Additionally, having a small pick tool on hand is advisable in case you need to remove debris or bent components.
Now, let's get started with the process:
- Inspect the fuel lines and identify any dirt, debris, or corrosion that may be present. Clean the connections if necessary. Soaking the connections in carb cleaner and then using compressed air to blow them out is a recommended method to ensure a thorough cleaning.
- If applicable, push the ends of the fuel lines towards each other and maintain pressure during the removal process. This helps prevent the tool from bottoming out on the retaining ridge.
- Insert the fuel line removal tool into the fuel line fitting. Ensure that the tool is the correct size and properly aligned. The tool should be designed to hold the garter spring out, aiding in the separation of the fittings.
- With the tool inserted, gently twist and jiggle the tool to loosen the connection. This motion helps break up any debris or rust that may be present.
- Once the connection is loosened, carefully pull the fuel line away from the tank. Be cautious not to damage the surrounding components.
- If the fuel line still doesn't come off, there might be an issue with the retaining clip or bail. In this case, you may need to use a small pick tool to reach between the filter nipple and the coupling to release the clip or bail. This step may require some force, and the bail may become deformed and need to be replaced.
- After successfully removing the fuel line, remember to clean any fuel deposits on the fittings to make future assembly and disassembly easier.
Remember to work carefully and patiently throughout the process. Removing fuel lines can be challenging, and it may take some time and effort to achieve success. Always refer to reliable sources or seek professional assistance if you have any doubts or encounter significant difficulties.

Pushing in buttons or tabs and pulling
To remove the fuel lines from the gas tank of a Ford F-350, you will need to apply some force and push the ends towards each other before inserting the tool. It is important to keep pressure on them while doing it to prevent the tool from getting stuck on the retaining ridge of the fuel line.
The fuel lines should have little plastic buttons or tabs that you need to press and then pull the line off. You can use a fuel line removal tool, which is available at most auto parts stores. Make sure you are forcing the tool into the fitting and the fitting onto the tool while simultaneously pulling the whole gaggle away from the line.
If you are using a metal scissor-style tool, it might be too big and unable to disconnect the line no matter how hard you pull. In this case, you can try using the smaller plastic removal tools, which are more effective in disconnecting the fuel lines.
Additionally, you can try pushing the line in further and using a smaller removal tool, twisting the line back and forth to break up any debris or rust. It is also recommended to spray the fuel line with WD-40 or a similar lubricant before attempting to remove it.
It is important to note that removing the fuel lines from the gas tank can be challenging, and you may need to try different tools and techniques before finding one that works for your specific vehicle.

Replacing the whole line if broken
If your fuel line is broken, you will need to replace the entire line. This can be caused by corrosion or debris kicked up from the tire, removing the paint or coating on the line. Before you begin, it is important to note that you will be working with gasoline, so some precautions are necessary. Always work in a well-ventilated area to avoid gas fumes, and have a fire extinguisher on hand. It is also recommended that you wear protective clothing, such as long sleeves and pants, and eye protection.
To replace the entire fuel line, you have three options:
- Replace the entire line with a pre-bent line: This option is available from aftermarket and new car dealer sources. It is the most expensive and labor-intensive option, but it returns the vehicle to like-new condition and is the longest-lasting repair.
- Bend your own lines: This option requires investing in bending and flaring tools, as well as quick disconnect fitting tools. This can be a good investment if you plan to do more of your own auto repairs in the future, but it will require you to carry a basic assortment of fittings.
- Nylon tubing: Nylon tubing can be used for an entire length of the fuel line or just a section. This option is cost-effective and time-efficient, especially when pre-bent lines are not available. With the correct fittings, factory-style, quick-disconnect fittings can be joined with metal lines or replace a section of a metal line.
It is important to note that simply replacing a section of a leaking line may not be sufficient, as corrosion elsewhere may cause another leak. Always make sure to have the correct replacement parts and tools before beginning any auto repairs.
