What You'll Learn
Raise the car and remove the drain plug
To start draining the fuel tank of your 1994 Toyota Corolla, you will need to raise the car to gain access to the fuel tank. This can be done by using a car jack to lift the car and providing a safe and stable base to work from. Make sure the car is secure and will not roll or shift while you are working.
Once the car is raised, you can locate the drain plug at the bottom of the fuel tank. Place a suitable container underneath the tank to catch the fuel. The container should be specifically designed for fuel and be able to hold the volume of fuel in the tank.
The next step is to remove the drain plug. This will allow the fuel to start draining from the tank. Be careful when removing the plug, as fuel may start to spill out immediately. Have a cloth or rag ready to wipe away any spills or leaks.
If your Corolla does not have a drain plug, an alternative method to drain the fuel is to disconnect the pipe from the fuel filter and attach a hose. Place the other end of the hose into a fuel collection container. You can then apply 12V directly to the fuel pump's connector to start the siphoning process.
Make sure you work in a well-ventilated area when draining fuel and take the necessary precautions to avoid any sparks or open flames.

Disconnect the fuel pump
To disconnect the fuel pump in a 1994 Toyota Corolla, you will need to access the pump, which is located inside the fuel tank, underneath the rear seats.
First, remove the rear seat cushion by lifting it up and releasing the clips on each side, then pulling it out. Next, unplug the fuel pump's electrical connector to depressurize the fuel system. You can then open the gas cap on the outside. Crank the engine for 3-4 seconds and wait for it to stall. Now, disconnect the car's negative battery cable.
Remove the fuel pump's access cover—it may be secured by butyl tape and need prying off, or it may be screwed in place. If screwed in, remove the four screws. With the access cover removed, you can now disconnect the fuel pump wire connector from the service hole under the seat.
You may now need to release fuel pressure and disconnect the hoses, inlet, return, pressure, and vacuum hoses.

Siphon with a hose
To drain the fuel tank of a 1994 Toyota Corolla, you can siphon with a hose. Here's a step-by-step guide on how to do it:
Firstly, it is important to raise the vehicle to gain access to the fuel tank. Place a suitable container underneath the tank to collect the drained fuel. You can then begin the siphoning process by following these steps:
Step 1: Position the Hose
Place one end of the hose into the fuel tank, ensuring it reaches the bottom. The other end of the hose should be placed into the container you've positioned to collect the fuel. Make sure the container is on a stable, lower surface. If needed, you can anchor the hose with an object to keep it in place, but be careful not to block the fuel flow.
Step 2: Start Siphoning
There are a few ways to start the siphoning process without using your mouth, as it is not recommended to siphon gasoline this way. One method is to use a second hose attached to a faucet. Turn on the faucet to fill the first hose with fuel, then turn it off and disconnect the second hose. Another method is to use an auto siphon or a manual pump to get the fuel flowing.
Step 3: Continue Siphoning
Once the siphoning process has started, the fuel will continue to move from the tank to the container until the tank is empty or you stop the process. Be careful to watch the fuel level in the hose to avoid any spillage or accidentally swallowing any fuel.
Step 4: Finish Up
When you've drained as much fuel as needed, simply remove the hose from both the tank and the container. Make sure to properly dispose of the drained fuel and clean up any spills.
Remember to exercise caution when handling gasoline and ensure you are in a well-ventilated area.

Drill a hole at the bottom
Drilling a hole at the bottom of your 1994 Toyota Corolla's fuel tank is not the recommended method for draining it. The correct way to drain the fuel tank is to follow these steps:
First, raise the vehicle to access the fuel tank. Next, remove the drain plug from the bottom of the tank and let the fuel drain into a suitable container. Ensure you do not dent the bottom of the tank. Following this, remove the fuel tank protector shield and the filler cap. Then, disconnect the fuel pump and gauge sending unit wiring harnesses, as well as the filler neck/overflow pipe from the tank. Disconnect the fuel supply and return hoses from the tank pipes, and the breather hose from the tank pipe. Cover the openings in the tank to prevent dirt from entering.
Support the fuel tank with a transmission jack, then remove the fuel tank strap bolts. The straps will swing away from the tank. Finally, lower the jack and the tank from the underside of the vehicle.
It is important to note that you should not drill a hole in your fuel tank as it may cause fuel leakage and potentially dangerous situations.

Disconnect filler neck/overflow pipe
Disconnecting the filler neck/overflow pipe from the tank is a crucial step when draining the fuel tank of a 1994 Toyota Corolla. This process is part of a larger sequence of steps that must be carefully followed to ensure the safe and effective drainage of the fuel tank.
To begin disconnecting the filler neck/overflow pipe, it is essential to have already raised the vehicle to gain access to the fuel tank. This can be done using a jack or a lift, ensuring the vehicle is securely supported. Once you have easy access to the tank, locate the filler neck/overflow pipe. This pipe is connected to the fuel tank and plays a role in supplying fuel to the engine.
The next step is to carefully disconnect the filler neck/overflow pipe from the tank. Before beginning this step, ensure you are wearing the appropriate protective gear, including gloves and eye protection. Use the correct tools to loosen any clamps or fittings holding the pipe in place. You may need to refer to a repair manual specific to your vehicle for detailed instructions on accessing and disconnecting this component.
After successfully disconnecting the filler neck/overflow pipe, set it aside safely. It is important to note that fuel may still be present in the pipe, so have a suitable container or drip pan ready to catch any fuel that may spill or leak. Additionally, be cautious of any sharp edges that could cause injury or damage to surrounding components.
Once the filler neck/overflow pipe is disconnected and safely set aside, you can continue with the next steps in the fuel tank drainage process. Remember to refer to a qualified repair manual or seek the assistance of a professional if you are unsure about any part of the procedure. Safety should always be the top priority when working on your vehicle.
