It is important to disconnect the negative terminal before the positive to avoid any electrical short circuits.

Next, locate the positive power connection, which is typically red in colour. Again, use your ratchet and socket to carefully disconnect this terminal. With both terminals disconnected, you have now safely disconnected the battery.

It is always a good idea to follow general electrical safety advice when working with car batteries. Car batteries can contain dangerous chemicals, so it is important to be cautious and wear appropriate protective gear, such as gloves and eye protection. Additionally, batteries can produce explosive gases, so ensure the work area is well-ventilated and avoid any sources of ignition.

By following these steps, you can safely disconnect the battery in your 2002 Ford Mustang, allowing you to proceed with changing the fuel pump or performing other maintenance tasks.

Jack up the car and drain the fuel tank

Jacking up your car and draining the fuel tank is a crucial step in changing the fuel pump in your 2002 Ford Mustang. Here is a detailed guide on how to do it:

First, you'll need to position your car on a flat, level surface and engage the parking brake. Place jack stands securely underneath the car to support the weight of the vehicle. Now, locate the jacking points on the car's frame and position the jack underneath. Ensure the jack is in contact with the frame and slowly raise the car to the desired height.

With the car securely raised, you can now access the fuel tank. Place a drain pan or container underneath the tank to catch the drained fuel. Next, locate the fuel lines connected to the tank. Before disconnecting any lines, it is crucial to relieve the pressure in the fuel system. To do this, simply open the gas cap on your Mustang. Now, carefully disconnect the fuel lines from the tank. Some fuel may spill, so be prepared with rags or towels to absorb any spills.

Once the lines are disconnected, you can now drain the fuel. If your Mustang has a fuel drain plug, you may need to use a socket wrench or vise grips to loosen and remove it. If your tank does not have a drain plug, you can siphon the fuel out using a hose or a manual siphon pump. Alternatively, you can use an electric siphon pump to speed up the process. Ensure you drain the tank as much as possible to reduce the weight and make it easier to handle.

With the tank drained, you can now lower it for easier access to the fuel pump. Slowly lower the jack until the tank is accessible. If needed, use a floor jack to support the tank and prevent it from dropping too quickly. Once the tank is lowered, you can proceed to remove the fuel pump. Remember to take necessary safety precautions when working with fuel, and always dispose of the drained fuel properly.

Remove the bolts to the fuel tank straps

To remove the bolts to the fuel tank straps of a 2002 Ford Mustang, you'll need to first make sure the car is elevated and secure. You can do this by opening the hood and disconnecting the negative battery cable. You should also relieve any pressure from the fuel system by locating the Schrader valve on the fuel rail and removing the cap. Use a small flathead screwdriver or similar tool to depress the valve.

Now, you can use a lift or jack stands to elevate the car and get it to a safe working height. Position a drain pan underneath the fuel filter.

The next step is to remove the safety clips and disconnect the hard lines and filter. Loosen the clamp with an 8mm socket and move it out of the way. Remove the filter from the bracket.

At this point, you can disconnect the fuel pump electrical connection. Then, position two jacks underneath the tank cover and lift them until they make contact.

Now you're ready to remove the bolts from the fuel tank straps. These are 13mm bolts, and you'll need to loosen and remove them from both the rear and front of the tank on the passenger side, as well as the front of the tank on the driver's side.

Once these bolts are removed, you can hold the strap and swing it down by hand. This will give you access to the driver-side EVAP connections, which you can now disconnect.

Make sure to follow safety precautions and refer to a qualified mechanic or repair manual for additional guidance if needed.
