Replacing The Fuel Pump In An Au Falcon: Step-By-Step Guide

If you're looking to change the fuel pump on your Ford Falcon AU, there are a few steps you'll need to follow. Firstly, locate the pump and ensure the area around it is clean to prevent anything from falling into the fuel tank. Disconnect the wiring from the pump, and start your car, letting it run until it dies. Turn the key a few more times to depressurise the fuel line, and then disconnect your battery. Remove the fuel lines and the retaining ring holding the pump in place, being careful not to let anything fall into the tank. Lift out the old pump, and replace it with a new one, refitting all the components. Your car should start after a few seconds of priming.

Ensure the area around the fuel pump is clean

To change the fuel pump on an AU Falcon, it is important to ensure the area around the fuel pump is clean. This is a crucial step to prevent any debris or contaminants from falling into the fuel tank, which could cause damage or affect the performance of your vehicle. Here are some detailed instructions to ensure a clean work area:

Firstly, locate the fuel pump, which is usually in the boot, and identify the black metal cover that needs to be removed. Place a clean cloth or a piece of cardboard on the ground directly under the fuel pump to catch any spills or debris. This will help contain the mess and make cleaning up easier.

Next, gather the necessary tools and materials, such as a screwdriver, wrenches, and a replacement fuel pump, if you have one. Ensure these tools are also clean and free of any dirt, grease, or other contaminants. It is recommended to wear gloves during this process to avoid direct contact with fuel or oils and to protect your hands from dirt.

Before beginning any work, use a vacuum or compressed air to remove any dust, leaves, or other debris that may be present around the fuel pump. Pay close attention to tight spaces and crevices, as dirt can accumulate in these areas. Additionally, ensure that the fuel lines and connections are free of any dirt or debris. Use a clean, dry cloth to wipe down the area, including the fuel tank, pump, and surrounding components.

During the process of changing the fuel pump, be mindful of any foreign objects that could fall into the tank. Always check the area for dropped tools, screws, or other small parts. Keep a bright light source nearby to illuminate the work area and help you spot any potential contaminants.

Finally, once the new fuel pump is installed, take a few minutes to inspect the area for any remaining dirt or debris. Use a clean cloth to wipe down the area again, ensuring that no residue or contaminants are left behind. This attention to cleanliness will help ensure the proper functioning of your vehicle's fuel system and prevent potential issues down the road.

Disconnect the wiring from the pump

Disconnecting the wiring from the pump is a crucial step in changing the fuel pump on an AU Falcon. Here is a detailed guide on how to do this:

Firstly, locate the pump and ensure that the area around it is clean. You don't want any debris falling into the fuel tank. Once you have located the pump, you will see a plug that connects to a bayonet fitting with wires. These wires are the power source for the fuel pump, and they need to be carefully disconnected. Using a suitable tool, gently pry or unclip the wiring harness from the pump. Be careful not to damage the wires or the connectors. Once disconnected, set the wiring harness aside, ensuring it doesn't fall into the fuel tank or any other hard-to-reach places.

At this point, it is important to depressurise the fuel line. To do this, start your car. It should run for a minute or so and then die as the fuel in the line is used up. Turn the key over a few more times to ensure the fuel line is completely depressurised. Now, disconnect the battery before proceeding further. Safety is paramount when working with fuel systems, so taking these extra steps is crucial.

Now that the wiring is disconnected and the fuel line is depressurised, you can proceed to the next steps of removing the fuel lines and the retaining ring holding the pump assembly in place. Remember to work carefully and deliberately to avoid any mishaps.

Depressurise the fuel line

Depressurising the fuel line of your AU Falcon is a crucial step before removing the fuel pump to ensure your safety and avoid fuel leaks. Here's a detailed guide on how to do it:

Firstly, locate the fuel pump and ensure the area around it is clean and free of debris. This is important to prevent anything from falling into the fuel tank. Once you've identified the fuel pump, disconnect the wiring connected to it. After disconnecting the wiring, attempt to start your car. The car engine should run for a brief period, around a minute or so, before eventually dying as the fuel in the line is used up.

At this point, turn the key in the ignition a few more times to be certain that the fuel line is completely depressurised. This step is important as it ensures that the pressure in the fuel line is released, reducing the risk of fuel leakage when you disconnect the fuel lines. Once you're confident that the fuel line is depressurised, you can proceed to the next step.

Disconnect your car battery to ensure that no power is supplied to the fuel pump. Now, carefully remove the fuel lines connected to the pump. Be cautious when handling the fuel lines, as they may still contain some residual fuel. Pay attention to any retaining clips or clamps holding the fuel lines in place, and gently remove them without causing any damage.

With the fuel lines disconnected, you can now focus on the large retaining ring that holds the pump assembly in place. Remove this retaining ring, being cautious not to let any foreign objects fall into the tank. Once the retaining ring is off, carefully lift out the old fuel pump.

It is important to note that working with fuel and electrical systems can be dangerous. If you are unsure or uncomfortable at any point, it is always best to consult a qualified mechanic or seek professional assistance. Safety should be your top priority.

Disconnect the battery

Disconnecting the battery is a crucial step in changing the fuel pump on an AU Falcon. It is important to ensure that you have disconnected the battery before removing the fuel lines and the retaining ring holding the pump assembly in place. This is a safety measure to prevent any accidental sparks or electrical shorts that could occur during the fuel pump replacement process.

To disconnect the battery, locate the negative terminal, which is usually marked with a "-" symbol or a black cover. Using a suitable size wrench or socket, loosen the nut that secures the negative battery cable to the terminal. Be careful not to let the wrench touch any other metal parts of the car, as this could cause a short circuit. Once the nut is loose, carefully remove the cable from the terminal. You may need to wiggle it gently to detach it.

After removing the cable, make sure that it is secured away from the battery. You can use a cable tie or an insulated clamp to hold it in place. This will prevent the cable from accidentally touching the battery terminal and causing a short circuit.

It is also important to note that modern cars, such as the AU Falcon, may have multiple batteries or a complex electrical system. In some cases, there may be a fuse box or other electrical components located near the battery. Take note of these components and be careful not to disturb them during the fuel pump replacement process.

Overall, disconnecting the battery is a critical step in ensuring a safe and successful fuel pump replacement on an AU Falcon. By following the proper procedures and taking the necessary precautions, you can help ensure that the job is done efficiently and effectively.

Remove the fuel lines and retaining ring

To remove the fuel lines and retaining ring of your AU Falcon, start by locating the pump. Once you have located the pump, ensure that the area around it is completely clean to prevent anything from falling into the fuel tank.

Next, disconnect the wiring from the pump and start your car. It should only run for a minute or so before dying. Turn the key over a few more times to ensure that the fuel line has depressurised. Now, disconnect your battery.

At this point, you can remove the fuel lines. Be sure to push them in and then release them by moving the plastic clips in the opposite direction. Once the fuel lines are removed, you need to undo the large clamp holding the pump assembly in place.

Now, take a large screwdriver and a mallet, and tap the plastic ring anticlockwise to loosen it. Once the ring is loosened, remove it, and you will have access to the plastic assembly and the fuel pump.
