What You'll Learn
Removing the rear fuel tank from a Ford F-150
Step 1: Prepare the Necessary Tools
Before beginning the removal process, ensure you have the required tools. For a Ford F-150, you may need a quick-connect removal tool, pliers, rubber hoses, bolts, and hose clamps, and a fuel line disconnect tool.
Step 2: Drain the Fuel Tank
Release the gas line pressure and drain as much fuel as possible from the tank and lines. This step is crucial to avoid fuel spraying when you disconnect the lines. Work in a well-ventilated area, and ensure there are no open flames or heat sources nearby.
Step 3: Disconnect the Fuel Lines
Locate the fuel lines connected to the rear tank. If your F-150 uses plastic clips, you may simply need to remove the clips to detach the lines. For models with metal lines, you may need to use a disconnect tool. Collapsible disconnect tools are available, which can be inserted into the line to collapse the "fingers" holding the line in place. Spraying lube at the tool's insertion point may also help.
Step 4: Cap and Secure the Lines
Once the lines are disconnected, cap them securely to prevent fuel leakage. You can use rubber hoses and bolts with hose clamps to cap the lines. Ensure that all lines, including the breather tube, are properly capped and tied up to the truck's frame.
Step 5: Disconnect the Fuel Pump
The next step is to disconnect the fuel pump. Unplug the wires connected to the rear fuel pump to ensure it is no longer active.
Step 6: Remove the Rear Fuel Tank
With the fuel lines and pump disconnected and capped, you can now remove the rear fuel tank. This step may vary depending on your model, but it typically involves lowering the tank and detaching any remaining connections. Be cautious, as the tank can be heavy and cumbersome.
Step 7: Address the Front Tank
After removing the rear tank, you'll need to make adjustments to the front tank. Ensure that the front tank's fuel line is connected directly to the fuel filter. Leave the switch on the dashboard set to the front tank. Additionally, consider treating old fuel in the front tank with a stabilizer or seafoam to clear up any junk and improve its quality.
Step 8: Test and Refill
Finally, test your truck to ensure it runs properly on the front tank only. You can now refill the front tank with fresh fuel and enjoy leak-free, efficient performance.
Remember, always exercise caution when working with fuel systems, and if you're unsure about any steps, consult a professional or a trusted mechanic.

Disconnecting fuel lines at the tank
There are a few methods that can be used to disconnect the fuel lines. One method is to use a quick-connect removal tool, which can be purchased from Ford or another manufacturer. This tool is designed to be shoved down inside the fitting to pop it off. If you are having trouble fitting the tool, try pushing the fuel line into the connector harder and twisting the connector side to side to free the teeth inside. Then, while maintaining pressure, insert the tool and push it in as far as it will go.
Another method is to use a neat trick with a short piece of plastic round tube that is open on both ends. Cut the tube down the middle, longways, so that it can fit around the gas line. Pull the fuel line connection side away as if you are taking it off, then slide the plastic tube inside the connection. Push the connection toward the tube, ensuring that the tubing does not move. With one motion, slide the connection and tube off the fitting at the same time.
If you are using the quick-connect removal tool and the fingers are not free of the catch ring before insertion, or if there is dirt behind them, they may become bent and semipermanently lock the coupling together. In this case, the coupling can be forcibly separated, but it will severely damage the bail. Alternatively, a small pick tool can be inserted between the filter nipple and the coupling to remove the bail, which can then be bent back into shape and reinstalled.
Additionally, it is important to note that a magnet will not pick up the fuel lines. If you are fishing for something with a wire, it may be easier to just force your hand through the mess in the front driver's corner.
Finally, always exercise caution when working with fuel lines. Gasoline, methanol, and oxygenated fuels are toxic and flammable, so keep cigarettes, sparks, open flames, and other sources of ignition away from the vehicle.

Using a quick-release tool to disconnect fuel lines
Disconnecting fuel lines with a quick-release tool can be a challenging task, as fuel lines are often tightly secured and prone to rust and debris buildup. Here is a detailed guide on using a quick-release tool to disconnect fuel lines, specifically for a 1990 Ford vehicle.
First, it is important to gather the necessary tools. A quick-release or quick-disconnect tool designed for fuel lines is required. These tools can be purchased at auto parts stores or online. Metal tools are generally recommended over plastic ones, as they are stronger and less likely to break during the process. Additionally, needle-nose pliers or "spreader" pliers may be useful to help push the tool into the fitting.
Before beginning the disconnection process, it is important to take safety precautions. Wear protective gear, such as gloves and eye protection, to shield yourself from any fuel spillage or debris. Ensure the vehicle is parked on a level surface, engage the parking brake, and allow the vehicle to cool down if the engine has been running recently. It is also recommended to relieve the fuel system's pressure via the Schrader valve in the engine compartment.
Now, locate the fuel lines you need to disconnect. For a 1990 Ford, the fuel line setup may be different from later models. The lines are likely secured with metal or plastic clips. Remove these clips before attempting to disconnect the lines. Some users have reported success by simply pulling out the plastic clip and then sliding out the fuel line.
If the lines are rusted or stubborn, a quick-release tool will be necessary. Insert the tool into the fuel line connector, ensuring it is as close to the fuel line as possible. Gently push the tool into the fitting, being careful not to force it if it doesn't easily slide in. You may need to use pliers to help push the tool into place. Once the tool is inserted, gently push the connector together while simultaneously inserting the tool. This action should cause the tool to expand outward, pushing the prongs or "teeth" of the connector towards the outside and releasing the fuel line.
In some cases, dirt and grime may prevent the quick-release tool from fully disengaging the prongs. To address this, you can use a few shots of brake cleaner to help loosen and remove any accumulated debris. Additionally, ensure that you are using the correct size of the tool for the fuel line you are working on.
By following these steps and exercising patience, you should be able to successfully disconnect the fuel lines using a quick-release tool. Remember to work carefully and refer to online forums and communities for additional tips and tricks for your specific vehicle model.

Replacing the fuel rail or fuel line
To replace the fuel rail or fuel line of a 90 Ford, you will need to purchase a new fuel line. You can either buy an OEM fuel line from Ford or an aftermarket one. While the former is more expensive, it is a better option to prevent leaks.
Before you start, ensure your truck is cooled off, and you have eye protection and hand protection. It is also important to work in a well-ventilated area, without any open flames or heat sources nearby.
First, release the gas line pressure or drain as much gas out of the line as possible to avoid spraying gas when you disconnect the line from the fittings. Disconnect the fuel line from the filter. You will either need to purchase special disconnect clips or fabricate your own using a piece of plastic tubing. Be cautious as some fuel may spray or leak out of the line.
Next, use a 13mm ratchet with an extension to remove the bolt that holds the fuel rail bracket onto the transmission. You can use some PB Blaster or WD40 to help break the bolt loose. Carefully take the mount off the transmission to give you more room to work on the fuel rail when cutting the line.
Now, get your Midget pipe cutter and begin cutting right after the bend. Prepare your 3/8", 2' Fuel-Injected Fuel Rated hose with the 3 Fuel-Injected Hose clamps that fit 3/8" ID - 5/16" ID hoses. Slip the hose onto the fuel rail and use a screwdriver to tighten the clamps down. Be careful not to over-tighten, or you may crush the line or bust the hose clamp. Route the hose away from the catalytic converter and exhaust pipes.
Finally, slip the other end of the hose onto the fuel filter and tighten the hose clamp. Check for any leaks by cycling the ignition from "Off" to "Run" several times and carefully inspecting the hose connections.
