What You'll Learn
Disconnecting the front fuel tank
If you do decide to proceed with disconnecting the front fuel tank, you will need to release the gas line pressure and drain as much gas as possible from the line to avoid spraying gas when disconnecting the line from the fittings. Ensure you are working in a well-ventilated area, and do not smoke or have any open flames or heat sources nearby.
You will then need to disconnect the fuel line from the filter. This can be done by purchasing special disconnect clips or fabricating your own using a piece of plastic tubing (such as a marker cap) to disengage the safety clips in the coupler. Be cautious, as some fuel may spray or leak out. Use a 13mm ratchet to remove the bolt holding the fuel rail bracket onto the transmission, and lubricate the bolt if necessary to help it break free.
Additionally, you may need to remove the old hose from the access pipe. If the hose is stubborn or leaves residue, use a pipe cutter to cut it right at the end of the hose.
For the 1993 F-150 model, there is also a neat trick shared by another F-150 owner. Find a short piece of plastic tubing that is open on both ends and cut it down the middle. Make sure it fits around the gas line. Pull the fuel line connection side away as if you were taking it off. Slide the plastic tube inside the connection and push the connection toward the tube while preventing the tubing from moving. With a single motion, slide the connection and tube off the fitting simultaneously.
Finally, refer to a schematic diagram to identify the wires with power when in the rear tank, and disconnect and jumper them together. Also, locate the sending unit wires and jump them as well.

Removing the rear fuel tank
Step 1: Prepare the Necessary Tools
Before beginning the removal process, ensure you have gathered all the required tools. This includes a fuel line disconnect tool, pliers, rubber hoses, hose clamps, and any other specialized tools recommended for your vehicle.
Step 2: Address the Fuel Leak
If your rear fuel tank is leaking, as mentioned in your query, it is essential to address this issue first. Refer to a mechanic or a Ford dealership for guidance on repairing or replacing the leaking component.
Step 3: Disconnect the Fuel Lines
To remove the rear fuel tank, begin by disconnecting the fuel lines. This process can vary depending on the type of fuel line fittings your vehicle has. The 1993 F-150 may have push-style fittings or push-and-lock style fittings:
- For push-style fittings, you may need to push buttons on both sides of the connector or firmly push a single button on one side and then pull to disconnect.
- For push-and-lock style fittings, the process may be similar to the push-style but with an additional locking mechanism for added security.
Step 4: Drop the Fuel Tank
Once the fuel lines are disconnected, you can proceed to drop the rear fuel tank. This step may require breaking tubes connected to the fuel pump using pliers and capping the tubes with rubber hoses and hose clamps, as mentioned in your query.
Step 5: Block the Vapor Hose
As noted by one source, there will be a vapor hose that runs to the charcoal canister (part of the evaporative system). Ensure this hose is blocked to prevent any vapor leakage.
Step 6: Join the Two Rear Lines
After removing the rear fuel tank, it is essential to join the two rear lines together to ensure the fuel system remains functional.
Step 7: Consult a Mechanic
If you encounter any challenges during the process or have doubts about your ability to safely remove the rear fuel tank, it is always best to consult a certified mechanic or a Ford dealership for guidance.

Using disconnect tools
When removing fuel lines from a 1993 F150, there are a variety of disconnect tools that can be used. The specific tool you will need depends on the type of fuel line connection you have.
For quick-release connections, a quick-connect removal tool can be used. This type of tool is designed to be shoved down inside the fitting to pop it off. It is important to relieve the fuel pressure in the line before attempting to disconnect it.
If you are dealing with a fuel filter that is held in place by a clamp, you can use a pry bar or a similar tool to pry the clamp open and then wiggle the filter out. In some cases, you may need to cut the fuel pump access panel before attempting to disconnect the fuel line.
For tight spaces, a small tool such as the 5/16 performance tool or the second smallest tool in the Lisle set may be required. This type of tool can be slipped over the filter end and then pushed towards the line so that it slips into the connection.
In some cases, a plastic tube can be used to disconnect the fuel line. Cut a short piece of plastic tube that is open on both ends and slice it down the middle longways. Place it around the gas line, then slide the connection and tube off the fitting in one motion.
If you are dealing with a flexible hose connection that is leaking, you may need to cut the rigid tubing on both ends using a hacksaw and then reconnect them using a new length of hose and clamps or compression fittings.
It is important to note that working on fuel lines can be dangerous, and it is always recommended to exercise caution and consult a professional if you are unsure about the process.

Disconnecting the fuel line from the filter
Before beginning this task, it is crucial to prioritise safety. Always use eye protection and do not smoke while performing maintenance on your fuel system. Additionally, make sure you are working in a well-ventilated area and do not have any open flames or heat sources nearby.
Now, to disconnect the fuel line from the filter, you will need to release the gas line pressure to avoid spraying fuel when you disconnect the line from the fittings. On the passenger side fuel rail (located in the engine), there is a Schrader valve that you can depress to depressurise the lines.
Once the lines are depressurised, you can proceed with disconnecting the fuel line from the filter. There are a few different methods you can use to do this, depending on the tools you have available and the specific configuration of your fuel line connections.
One method is to use a quick-connect removal tool, which can be purchased from various auto parts stores. This tool is designed to be shoved down inside the fitting to pop the fuel line off.
Another method is to fabricate your own disconnect tool using a piece of plastic tubing, such as a marker cap or a piece of plastic round tube. You will need to cut the tubing down the middle longways so that it can fit around the gas line. Then, pull the fuel line connection side away as if you were taking it off. Slide the plastic tube inside the connection, pushing the connection toward the tube without allowing the tubing to move. With one motion, slide the connection and tube simultaneously off the fitting.
Alternatively, if your fuel line connections have plastic clips, you may be able to simply pry them off with a screwdriver, and the lines should pull right off. However, these clips will likely break and need to be replaced, but they are inexpensive.
In some cases, you may need to use a combination of these methods or make adjustments based on the specific configuration of your fuel line connections. For example, if your fuel line connections have metal clips, you will likely need to use the quick-connect removal tool to disconnect them.
Once you have successfully disconnected the fuel line from the filter, be sure to completely remove the filter from both ends of the line. Use caution, as some fuel may still spray or leak out of the line.

Removing the fuel filter
Before you begin, ensure you are working in a well-ventilated area and do not smoke or have any open flames or heat sources nearby. It is also important to release the gas line pressure and drain as much gas out of the line as possible to avoid spraying when you disconnect the line from the fittings.
To remove the fuel filter, you will first need to disconnect the fuel line from the filter. You can either purchase specialised disconnect clips or create your own using a piece of plastic tubing, such as a marker cap, to disengage the safety clips in the coupler. Be sure to remove the filter from both ends of the line, and be cautious as some fuel may leak or spray out.
Next, locate and remove the bolt holding the fuel rail bracket using a ratchet. If the bolt is too tight, try using a lubricant to help break it free. If you are able to remove the old hose from the access pipe, you can avoid cutting the pipe. However, if the hose is stuck or leaves residue, use a pipe cutter to cut it at the end of the hose.
Now, you can remove the fuel filter. This may require a fuel line disconnect tool, which you can purchase or rent from an auto parts store. Choose the correct size, insert the open end into the female portion of the fuel line connector, squeeze to open the jaws, and push down firmly until the connection breaks off.
It is important to note that there are different types of fuel line fittings, such as push-style and push-and-lock style fittings. Push-style fittings may have buttons on both sides of the connector, which you need to push simultaneously to release. Alternatively, some push-style fittings have a button on only one side, which you push and then pull to disconnect. Push-and-lock style fittings are more secure than push-style fittings.
