What You'll Learn
The fuel pump is located externally
If your 1982 Toyota Supra has an external fuel pump, it will be located in front of the tank, on the side towards the front of the car.
To replace the fuel pump, you will need to purchase a new one that is compatible with your car. You may also need to replace the fuel filter, as a clogged filter is a common reason for the pump to fail. You will also need to buy some tools if you don't already have them, such as flare nut wrenches and wobble extensions.
First, make sure to relieve any pressure in the system by cranking the engine. You should also loosen the gas cap. Then, you can start to remove the fuel pump by undoing the hoses and unscrewing any screws. Be careful not to strip your fittings and use penetrating oil on any rusty bolts. You will also need to unplug the electrical connectors for the level sensor and pump.
Finally, install the new fuel pump and filter, making sure to pay attention to the correct positioning. Be careful not to kink the fuel line when you're finishing up.

Removing bolts holding the pump hanger
Removing the bolts that hold the pump hanger can be a tricky process, especially if the bolts are rusty. It is important to exercise caution during this step to avoid breaking the bolts. Here is a detailed guide on how to remove these bolts:
Before attempting to remove the bolts, it is recommended to apply penetrating oil to the bolts and let it sit overnight. This will help to loosen any rust or debris that may be causing the bolts to stick.
When you are ready to begin, make sure you have the appropriate tools, including a wrench or a ratchet. The size of the wrench or ratchet will depend on the size of the bolts holding your pump hanger. It is always a good idea to have a variety of sizes on hand, as you may encounter different bolt sizes during the removal process.
Locate the bolts holding the pump hanger in place. There may be multiple bolts, so make sure you identify all of them before beginning the removal process. Inspect the bolts for any signs of rust or damage. If the bolts are severely rusted, you may need to consider replacing them with new ones to avoid breakage.
Once you have identified the bolts and inspected them for damage, you can begin the removal process. Using your wrench or ratchet, carefully apply force to the bolts in a counter-clockwise direction to loosen them. It is important to be gentle during this step to avoid stripping the bolts or damaging the surrounding components.
If the bolts are particularly tight or difficult to remove, you may need to apply additional penetrating oil or use a bolt extractor tool. Do not force the bolts if they are not turning easily, as this can lead to breakage. Take your time and work carefully to ensure a successful removal.
Once the bolts are removed, set them aside in a safe place so that you can access them later if needed. With the bolts removed, you should now be able to access and remove the pump hanger. Remember to inspect the inside of the tank for any signs of rust or debris, as this can impact the performance of your new fuel pump.
Overall, the process of removing the bolts holding the pump hanger can be delicate and time-consuming, especially if you are dealing with rusty bolts. By following the steps outlined above and working carefully, you can successfully remove these bolts and proceed with the replacement of your 1982 Toyota Supra's fuel pump.

Inspecting the tank for rust
Inspecting the fuel tank for rust is a crucial step in maintaining your Toyota Supra and ensuring its longevity. Here is a detailed guide to help you through the process:
Preparation:
Before starting the inspection, make sure you have the necessary safety equipment, such as gloves, safety glasses, and a mask. If the fuel tank is still attached to your vehicle, you will also need a jack or lift to access it comfortably. It is also recommended to have rust removal tools, such as a wire brush or sandpaper, and chemical rust removers on hand. Ensure your vehicle is in a well-ventilated area to avoid inhaling harmful fumes from the fuel.
Draining the Tank:
Begin by draining any remaining fuel from the tank using a siphon pump. Collect the fuel in a suitable container for proper disposal. This step will allow you to assess the extent of rust accumulation and prepare for further action.
External Inspection:
Start your inspection from the outside of the tank. Check for visible signs of rust, corrosion, cracks, or dents. Pay close attention to the fittings, valves, connections, and support structures, ensuring they are intact and free from damage. Use leak detection equipment to identify any potential leak points.
Internal Inspection:
For a thorough inspection, you will need to empty the tank completely. This step is crucial as it allows access to the interior surfaces for a detailed examination. Once emptied, clean the interior of the tank to remove any sludge, sediment, or residues that may have built up over time.
Detailed Examination:
Proceed to inspect the internal surfaces for signs of corrosion, pitting, or other damage caused by rust. Use a bright light to illuminate the interior and carefully examine all accessible areas. Look for rust flakes, discoloration, or structural damage. If necessary, use ultrasonic testing equipment to measure the thickness of the tank walls and detect internal corrosion that may not be visible to the naked eye.
Taking Action:
After completing the inspection, it's time to take appropriate action. If you find extensive rust accumulation, consider seeking professional help from a certified mechanic or a shop specializing in restoring fuel tanks. They can advise you on the best course of action, which may include chemical treatments, electrolysis methods, or, in severe cases, fuel tank replacement.
Preventative Measures:
To prevent rust from forming in your fuel tank, consider the following:
- Regularly inspect your fuel tank for any signs of rust or corrosion.
- Keep the tank full to minimize moisture accumulation, which can lead to rust formation.
- Use fuel additives or rust inhibitors to stabilize the fuel and prevent corrosion.
- Ensure proper fuel storage practices and maintain high-quality fuel to reduce the risk of contamination and rust formation.
By following these steps and staying vigilant, you can effectively inspect your 1982 Toyota Supra's fuel tank for rust and take the necessary actions to ensure the optimal performance and longevity of your vehicle.
