Disconnect the battery and siphon the fuel from the tank

Disconnecting the battery and siphoning the fuel from the tank are crucial steps when replacing the fuel pump in a 1993 Ford Bronco. Here is a detailed guide on how to approach these steps effectively:

Disconnect the Battery:

Before beginning any work on your Ford Bronco, it is essential to disconnect the battery as a safety precaution. This will prevent any accidental electrical discharges or sparks that could potentially cause an explosion or fire, especially when working with flammable liquids like gasoline. Make sure to locate the battery and disconnect the negative terminal using an appropriate tool, such as a socket wrench or a combination wrench.

Siphon the Fuel from the Tank:

Working with a full fuel tank can be heavy and dangerous. Therefore, it is recommended to siphon as much fuel as possible from the tank before proceeding with the fuel pump replacement. Here are the steps to siphon fuel safely:

  • Tools and Safety: You will need a fuel siphon pump and a fuel container (jerry cans or similar). Always wear eye protection and work gloves to protect yourself from any fuel spills or splashes. It is also advisable to work in a well-ventilated area to avoid inhaling gasoline fumes.
  • Positioning the Vehicle: Park your Bronco on level ground to ensure stability during the process. Engage the parking brake and place wheel chocks behind the rear wheels for added safety.
  • Accessing the Fuel Tank: Depending on your Bronco's configuration, you may need to lift the vehicle slightly to access the fuel tank. Use a jack to safely raise the vehicle, following the manufacturer's instructions. Place jack stands for added support if necessary.
  • Siphoning the Fuel: Carefully insert the siphon pump into the fuel tank. Ensure that the pump is designed for fuel and follows the appropriate safety standards. Start siphoning by pumping the handle or using an electric pump if available. Continue until you have removed as much fuel as possible. Remember to direct the fuel into the container and handle the old fuel with care, as it may contain particles that can damage the new fuel pump.

By following these steps, you will be able to safely disconnect the battery and siphon the fuel from your 1993 Ford Bronco, making it ready for the next steps in the fuel pump replacement process.

Lift the truck and support the fuel tank

To replace the fuel pump of a 93 Ford Bronco, you will need to lift the truck and support the fuel tank. Here's a step-by-step guide:

First, park your Bronco on even terrain to ensure it is level and well-positioned for the repair. Put on eye protection and disconnect the battery to ensure safety. You will also need a range of tools for this job, including a fuel siphon pump, a fuel container, jack stands, a jack, a socket wrench set, a combination wrench set, a fuel line disconnect tool, and screwdrivers.

Next, siphon the fuel from the tank to make it lighter and easier to handle. It is important to do this carefully to avoid any spills or accidents. Once the fuel is removed, lift the rear of the truck to gain easier access to the fuel tank. A floor jack can be used to support the tank, ensuring it is centred properly.

Now, you can start to remove the components securing the fuel tank. Start by removing the tank straps, if your vehicle has them. Then, remove the tank shield. At this point, you should only lower the tank slightly, just enough to reduce tension on the fuel lines and the pump plug. Be careful not to put any strain on these components.

With the tank shield removed, you can now disconnect the fuel lines and pump plug. Carefully remove the tank from under the truck, taking care not to damage any surrounding components. Once the tank is out, open it and retrieve the fuel pump assembly for replacement.

At this stage, you can also take the opportunity to clean the fuel tank, both inside and out, and consider painting it if necessary. It is important to ensure the tank is free of any dirt, rust, or debris before reinstalling it.

Finally, reverse the steps to reinstall the new fuel pump and fuel tank. Ensure all connections are secure and refuel the tank with fresh fuel. It is recommended to use new fuel to reduce the risk of particles in old fuel damaging the new pump.

By carefully following these steps, you can successfully lift the truck, support the fuel tank, and gain access to the fuel pump for replacement in your 93 Ford Bronco.

Remove the tank straps, tank shield and filler neck

To remove the tank straps, tank shield and filler neck of a 1993 Ford Bronco, follow these steps:

Firstly, disconnect the filler neck from the fuel tank. Loosen the clamp joining the rubber hose to the filler neck, then open the fuel door and remove the bolts holding the filler neck. Skip this step if your Bronco does not have tank straps.

Next, remove the tank straps. There will be two bolts/nuts holding each strap, so remove these.

Now, remove the tank shield. There are a total of eight nuts/bolts holding it in place, so once those are removed, the tank will fall, so make sure it is properly supported.

At this point, you can lower the tank, just enough so that there is no tension on the fuel lines or the pump plug.

Disconnect the fuel lines and pump plug, and remove the tank from under the vehicle.

Now, you can open the tank and retrieve the fuel pump assembly.

Finally, reverse the steps to finish the procedure.

Disconnect the fuel lines and remove the tank

Disconnecting the fuel lines and removing the tank from a 1993 Ford Bronco is a complex process that requires a range of tools and safety precautions. Here is a detailed, step-by-step guide:

Firstly, ensure you are wearing eye protection and have taken all necessary safety measures. It is also recommended to clean the area underneath the vehicle to make it easier to work on.

Next, disconnect the electrical connector and all metal/rubber hoses going to the fuel pump. Cover the disconnected components with something to keep them clean and tuck them out of the way.

Now, for the fuel pump lines. This step requires a specific tool, which can be purchased at any local auto parts store. Slide the correct-sized tool into the fuel pump line and press in, then pull the fuel line back. It might take some effort, but it will eventually come apart.

At this point, you can undo the straps to make it easier to move the tank around. Don't forget to also undo the filler neck, as this will make it easier to remove the tank.

Slide whatever tool or equipment you are using to support the gas tank into place. A floor jack or motorcycle jack can be useful here, ensuring the tank is centred properly.

Now, unbolt the bolts on the front and rear of the skid plate. Take note that once these bolts are removed, the gas tank will no longer be supported, so ensure it is properly secured before continuing.

Once the tank is supported, you may need to lift the Bronco to pull the tank out. Make sure you clean the area before doing so, as you do not want dirt or debris falling into the tank.

Now, you can slide the locking ring to remove it. A screwdriver and hammer/mallet can be used for this step, but be careful not to create sparks.

With the locking ring removed, you can now access the fuel pump. Maneuver the fuel pump to get the float and sock out, being careful not to drop the sock into the tank.

Finally, undo the bolts and cut the wires off the fuel pump. You will need to splice the new fuel pump wires onto the sender unit. Once this is done, the fuel pump has been successfully disconnected, and you can remove the tank from the vehicle.

Remember, it is important to take your time and follow these steps carefully to ensure a safe and successful fuel pump replacement.

Open the tank, retrieve the fuel pump assembly and replace the pump

To open the tank of a 93 Ford Bronco, you'll need to ensure there is as little fuel in the tank as possible to minimize weight. Then, disconnect the filler hose, tank straps, and protective skid plate, which is all that holds the tank in place.

Once the tank is out, you can retrieve the fuel pump assembly. The pump is located inside a plastic module (housing) that sits within the fuel tank. To replace the pump, carefully open the top of the plastic housing and replace the old pump with a new one. You will also need to replace the fuel tank gasket and the sock strainer that goes over the bottom of the fuel pump housing.

When you're done, simply bolt the old module back into the tank and reconnect the wires.
