If you own a classic 1971 Porsche, you may need to remove the fuel tank for repairs or maintenance. This can be a tricky process, and it's important to take precautions when working with combustible liquids and vapors. It's recommended to work outdoors or in a well-ventilated area and wear protective gear, including eye protection and fuel-proof clothing. Before starting, you may want to drain the fuel tank as much as possible, using a hose or a hand pump. Removing the fuel tank typically involves disconnecting fuel lines and hoses, working underneath the car, and possibly raising the vehicle with a lift or jack stands for better access.

Jack up the car and remove rear wheels
Jacking up your 1971 Porsche and removing the rear wheels is a straightforward process, but it's important to take some key precautions to ensure your safety and make the task easier. Here's a detailed guide to help you through the process:
Park and Prepare:
First, find a suitable workspace. Park your Porsche on stable, level ground. Chock the wheels that you don't intend to remove, usually the front wheels. Engage the parking brake and put the transmission in "Park" if your car is automatic, or leave it in gear if it's a manual.
Locate Jack Points and Jack:
Refer to your Porsche's owner's manual to identify the designated jacking areas on your vehicle. Jack points can vary depending on the car model. Once you've located the jack points, it's time to get the jack ready. Take the jack out of the boot or refer to the owner's manual if you're having trouble locating it. Place the jack in position under the side of the vehicle, closest to the rear wheel that you'll be removing. Adjust the jack height until it fits securely into the jack point.
Jack Up the Car:
Operate the jack slowly and smoothly until the rear of the car is lifted, and the rear wheel is off the ground. Ensure that the car is stable and securely supported by the jack before proceeding.
Remove Rear Wheels:
Now that the rear of the car is lifted, it's time to remove the rear wheels. Start by removing the wheel nuts by hand. After they're removed, carefully pull off the rear wheel. If you're replacing the wheel, install the spare, and thread the wheel nuts on, tightening them securely.
Lower the Car:
Once the rear wheels are removed and any necessary work is completed, it's time to lower the car. Place the rear wheel back onto the wheel hub, and slowly lower the car using the jack. Remember to tighten the wheel nuts securely after lowering the car. If possible, tighten them to the specified torque using a criss-cross pattern.
Remember, working under a car always carries risks, so it's crucial to follow safety guidelines and use proper equipment. It's recommended to use jack stands to support the vehicle securely before getting under it. Additionally, always wear appropriate protective gear when handling car repairs, especially when dealing with fuel tanks and combustible liquids.

Disconnect the battery
To disconnect the battery of a 1971 Porsche, you will need to take a few important steps to ensure your safety and the integrity of the vehicle. Here is a detailed guide on how to do it:
Park your Porsche in a well-ventilated area, preferably outdoors, away from any open flames or sparks. Turn off the ignition and remove the keys. This is a crucial step to prevent any accidental startups during the process. Put on safety goggles and gloves to protect your eyes and skin from battery acid and corrosive materials.
Locate the battery. In most Porsche models, the battery is located in the trunk, under the hood, or in the front luggage compartment. You can refer to your 1971 Porsche's owner's manual to pinpoint the exact location.
Remove any covers or brackets securing the battery in place. This includes the battery hold-down bracket, which is designed to prevent the battery from moving during driving. Use an adjustable wrench or socket set for this step.
Now, you will disconnect the battery cables. Start with the negative (black) cable first to prevent short circuits. Loosen the nut on the negative terminal using your wrench or socket set, then remove the cable from the terminal. Ensure that the cable doesn't touch any metal parts.
Repeat the same process for the positive (red) cable. Loosen the nut on the positive terminal, remove the cable, and set it aside, keeping it away from metal parts. With both cables disconnected, your battery is now fully disconnected.
Finally, carefully lift out the old battery. Batteries can be quite heavy, so use proper lifting techniques and caution to avoid injury. Place the old battery in a safe area away from the work area.
Remember, working with car batteries can be dangerous due to the presence of corrosive materials and battery acid. Always prioritize your safety and follow established safety guidelines when performing any work on your 1971 Porsche.

Drain the fuel tank
To drain the fuel tank of a 1971 Porsche, follow these steps:
Firstly, get the car up as high as possible so that you have room to drop the old fuel tank and move it out of the way safely. A lift is best, but jack stands will also work. Remove the rear wheels to give yourself more room to work comfortably and improve lighting.
Next, take the cover off the fuel pump under the car. Use a pair of needle-nose vice grips to pinch the fuel hose and disconnect it, aiming it into a container. When the container is full, pinch the hose shut and get another container if necessary.
Once the tank is drained, you can disconnect the fuel line to the pump. Be sure to disconnect the battery before you begin. It is also important to wear appropriate fuel-proof protective gear for your skin and eyes, and to work in a well-ventilated area, preferably outdoors.
Finally, you can move on to removing the fuel tank.
