Disconnecting the fuel lines from the fuel filter
Before beginning any work on your fuel system, it is crucial to ensure your safety. Work in a well-ventilated area and take the necessary precautions to avoid any potential fire hazards. It is recommended to relieve the pressure in the fuel lines before proceeding. While some sources suggest that this step may not be necessary, it can make the process easier and safer.
To disconnect the fuel lines, you will need a fuel line disconnect tool. This tool is designed specifically for removing fuel lines and can be purchased from automotive stores. Ensure that you have the correct tool for your vehicle's make and model. Some Ford F-150 models may require a specific tool for fuel line removal.
Once you have the tool, insert it into the inside of the fuel line. Position the tool securely on the inside of the fitting, and then push the line outward. This action should release the spring or clip that holds the fuel line in place. You may need to apply some pressure and twist the tool while keeping it in position.
If the fuel lines are stubborn and difficult to remove, you may need to employ some additional techniques. Try pushing the line towards the filter or pump first, and then insert the tool. You may also need to twist and pull simultaneously while applying pressure to the tool. This process can be challenging, and it may take a few attempts to successfully release the fuel lines.
In some cases, fabricating plugs for the fuel lines can be an alternative solution. You can create these plugs using old bolts. Cut off the threads of the bolts and round over the edges. Push these modified bolts into the fuel lines and re-install the retainer clips. The fuel lines have an O-ring that will seal against the bolt, creating a secure connection. However, you may need to shape the bolt head slightly with a grinder to ensure a proper fit.
Remember to exercise caution throughout the process, as working with fuel lines can be dangerous. Always refer to your vehicle's manual or seek professional assistance if you are unsure about any steps or procedures.

Relieving pressure in the line
To relieve pressure in the fuel line of a 95 Ford F150, you can try the following methods:
Method 1
- Disconnect the negative battery cable using a wrench. This will prevent sparks, which could ignite fuel and fuel vapors.
- Locate the fuel pressure regulator on the fuel rail. The rail is mounted along the top area of the engine. Ensure that the regulator is vacuum-operated.
- With your hand, remove the vacuum hose from the top of the fuel pressure regulator.
- Connect a hand-operated vacuum pump to the top of the pressure regulator.
Method 2
- Locate the fuel pump fuse under the dashboard or in the engine compartment. It is usually located on the driver's side of the vehicle and may be marked for easy identification.
- Remove the fuse with your hand or a pair of pliers. Alternatively, you can remove the fuel pump relay with your hand.
- Start the engine and let it idle until it stalls.
- Disconnect the negative battery cable using a wrench.
- Search for the inertia switch around the trunk, rear compartment, or under the dashboard. Many Ford models have this shut-off switch to cut off fuel to the system in case of an accident. Consult your owner's manual if needed.
- Unplug the inertia switch's electrical connector.
- Start the engine and let it run until it stalls.
- Disconnect the negative battery cable.
Method 3
- Access the sending unit/fuel pump assembly on top of the fuel tank. Some vehicle models provide an access door to the fuel tank through the floor underneath the rear seat or under the trim in the trunk. For other models, you may need to raise the rear of your vehicle using a floor jack and support it on jack stands to access the assembly.
- If your model has an access door above the tank, either remove the rear seat by pulling the retaining strap or removing the trim on the floor of the trunk. The location of the access door varies by model.
- Remove the mounting screws on the fuel tank access door using a Phillips screwdriver or by pulling the butyl tape around the door. If the fuel pump is accessed from underneath, ensure the vehicle is secured on the jack stands before proceeding.
Method 4
- Disable the fuel pump by pulling the fuel pump relay or tapping the inertia switch.
- Start the engine and let it run until it dies.
- Locate the Schrader valve on the passenger side fuel rail.
- Remove the valve cap and briefly depress the center pin to burp the fuel lines. Alternatively, use the cap of a ballpoint pen to push the valve in.
- Always remember to loosen or remove the fuel filler cap when working on the fuel tank to relieve pressure buildup.

Removing the rear fuel tank
Firstly, it is important to understand the fuel system of the 1995 Ford F-150. This particular model is equipped with a dual-tank fuel system, which allows the vehicle to switch between the rear and front fuel tanks. The front fuel pump plays a crucial role in this system, as it determines whether the return gas goes to the front or rear tank. When the front pump is running, the gas is returned to the front tank. However, if the front pump is not functioning, the return gas is cycled back to the rear tank.
Now, if you are experiencing issues with the rear fuel tank, such as leaks, it may be necessary to remove and replace it. Before beginning the removal process, make sure you have the necessary tools and safety equipment, such as gloves and eye protection. It is also recommended to place a container underneath the tank to catch any spilled fuel.
The next step is to locate and disconnect the fuel lines connected to the rear tank. This can be a challenging task, as the lines may be rusty and difficult to access. One approach is to use pliers to break the tubes off the fuel pump and then cap the tubes with a rubber hose, a bolt, and hose clamps, as described by an F-150 owner. Ensure that both fuel lines and the breather tube are capped securely to prevent fuel leakage.
After the fuel lines have been disconnected and capped, you can proceed to remove the rear fuel tank. This may require lowering or dropping the tank, which can be physically demanding due to the weight of the tank and the limited space to work with. Once the tank is removed, you must join the two rear lines together to ensure the proper functioning of the fuel system, as mentioned by another F-150 owner.
Finally, with the rear fuel tank removed and the lines connected, you can now focus on the front tank. Ensure that the front tank fuel line is connected directly to the fuel filter. Additionally, you can leave the switch on the dashboard for the front fuel tank to maintain control over the fuel source.
By following these steps, you can successfully remove the rear fuel tank on your 1995 Ford F-150 and continue using the vehicle with the front fuel tank. Remember to exercise caution and seek professional assistance if you encounter any difficulties or complications during the process.
