What You'll Learn

Removing the fuel tank
First, you will need to prepare the vehicle for the fuel tank removal. Park the vehicle on a level surface and engage the parking brake to ensure it doesn't move during the process. It is also recommended to wear protective gear, such as gloves and eye protection, and have a suitable container ready to catch any spilled fuel.
Next, you will need to access the fuel tank. This may involve raising the vehicle to gain access to the undercarriage, where the fuel tank is located. Ensure the vehicle is securely supported before proceeding. Once you have located the fuel tank, you will need to disconnect the fuel lines and any electrical connections associated with it. Mark each line or connection before detaching them to ensure proper reassembly. Place the disconnected lines and connections in a safe location away from the work area.
Now, you are ready to remove the fuel tank. This process can vary depending on the vehicle's specific design. In some cases, you may need to remove bolts or brackets securing the fuel tank in place. Carefully lower the fuel tank, being mindful of any remaining fuel or vapors inside. Have a suitable container ready to catch any spilled fuel. Place the fuel tank in a well-ventilated area to allow any remaining vapors to dissipate.
Finally, dispose of any spilled fuel or vapors properly, following local regulations and guidelines. Ensure that you do not leave any open flames or ignition sources near the work area during the entire process, as fuel vapors can be highly flammable.
Remember, this is a general guide, and specific steps may vary depending on your vehicle's make and model. Always refer to a qualified mechanic or the vehicle's repair manual for more detailed instructions specific to your 1989 P30.

Using a pump
To drain your 1989 P30's fuel tank using a pump, you will need about six feet of a small 3/8-inch hose, a pump to draw the fuel out, and a receptacle to store the drained fuel. You should also have a fire extinguisher nearby in case of a fire.
Firstly, run the car as close to empty as possible. If you have the wrong fuel in the tank, do not run the car. Park the car and let it cool before starting to drain the fuel.
Now, stick the hose into the gas tank. Feed it until there is only one to two feet left before the pump. This part of the process may be harder for newer cars that have protective metal bulbs or screens that prevent gas from escaping in a crash. If you encounter this, you may need to seek a professional's help.
Next, take your larger tube (connected to the pump) and slip it over the smaller tube. Start pumping until the gas comes out. As you pump, have your receptacle ready to be filled. Hold onto the end of the hose, as it can start to move when the gas begins to flow.
Finally, remove the tube and refill the tank. You can reuse the drained gas or dispose of it properly.

Disconnecting the fuel fill hose
First, loosen the fuel filler cap to relieve the fuel tank vapor pressure. This step is important as it reduces the risk of fuel spraying out under pressure when you open the tank. Once you've loosened the cap, you can proceed to the next step.
Now, you need to raise the vehicle. This will give you better access to the fuel tank and its components. Make sure the vehicle is securely supported before proceeding.
Locate the fuel fill hose clamp at the tank. This clamp secures the fuel fill hose to the fuel fill pipe. Using the appropriate tools, carefully loosen the clamp. You may need to refer to your vehicle's repair manual to identify the exact location of the clamp and the tools required.
Once the clamp is loosened, you can carefully disconnect the fuel fill hose from the fuel fill pipe. Be prepared to catch any residual fuel that may spill out during this process. Have a suitable container and absorbent materials ready.
At this point, the fuel fill hose should be disconnected from the fuel fill pipe. You can now use a hand or air-operated pump device to drain the remaining fuel from the tank through the fuel fill hose. Ensure that you are in a well-ventilated area and follow all necessary safety precautions when handling fuel.
It is important to note that you should only perform this procedure when the engine is cool and never smoke or have any open flames nearby. Always refer to your vehicle's repair manual for specific instructions related to your 1989 P30 fuel system.

Using a rubber hose
To drain the fuel tank of a 1989 P30, one method you can use is to employ a rubber hose. This process will involve several steps and some additional tools, but it is a viable way to drain your fuel tank.
Firstly, you will need to loosen the fuel filler cap to relieve the fuel tank vapour pressure. Next, you must raise the vehicle. This step is important as it ensures you can access the fuel tank and related components, and it also helps to move the fuel towards the output. Once the vehicle is raised, you will need to locate the fuel fill hose clamp at the tank and loosen it. Be careful not to disconnect the hose just yet, as this step simply involves loosening it to prepare for the next steps.
Now, you can take your rubber hose and connect it to the fuel filter. Ensure that the hose is securely clamped to the filter and that it is long enough to reach a gas can or bucket placed below the vehicle. With the hose in place, you can now disconnect the fuel fill hose from the fuel fill pipe. At this point, you are ready to begin draining the fuel. Turn the key to start the fuel pump, and the fuel should begin flowing through the rubber hose into your gas can or bucket.
It is important to note that you should keep the pump running during the drainage process. Additionally, some sources suggest that running a fuel pump dry can be harmful to it, so be cautious and monitor the process closely. Once the tank is empty, you can then dispose of the drained fuel appropriately. Remember always to exercise extreme caution when handling flammable liquids like gasoline, and ensure adequate ventilation during the process.

Disposing of old fuel
It is important to dispose of old fuel safely and responsibly. Old fuel should not be poured onto the ground, as it will damage vegetation and harm the environment. It is also considered hazardous waste due to its flammability, so it should not be poured down the drain.
There are several ways to dispose of old fuel properly. One option is to take it to a local recycling centre or hazardous waste centre, which may accept it for disposal free of charge. Some townships offer collection at the town's recycling centre, where you can pour the old fuel into a large container with a funnel. Gas stations may also dispose of old fuel properly.
Another option is to filter the old fuel and use it in small equipment, such as lawnmowers, generators, or chainsaws. It is recommended to mix it with fresh gas and add a fuel stabilizer to prevent damage to the equipment. However, it is important to note that using old fuel in vehicles can be risky, as it may damage the fuel pump.
If you have a charcoal BBQ grill, old fuel can be used sparingly as lighter fluid. Alternatively, you can let the old fuel evaporate in the open air, although this may not be the most environmentally friendly option.
It is important to check with your local regulations and disposal facilities to determine the best way to dispose of old fuel in your area.
