Draining the fuel tank of a PT Cruiser can be a challenging task. While there are various methods suggested by PT Cruiser owners, such as disconnecting the vapor pipe near the fuel tank or removing the gas cap to release the flapper, the most effective approach may depend on the specific model year of the vehicle. Some older models, such as the 2001 PT Cruiser, may have a fuel tank drain plug located on the right rear side of the tank. However, this feature appears to be absent in later models, requiring more complex procedures to drain the fuel tank. It is essential to exercise caution when handling fuel and to prioritize safety measures to prevent any potential hazards.

What You'll Learn
Fuel tank drain plug location
The fuel tank drain plug location on a PT Cruiser depends on the model year of the vehicle. According to some sources, only the first batch of 2001 PT Cruisers had a fuel tank drain plug, and it was located on the right rear side of the tank, to the right of the fill tube and in front of the coil spring. However, other sources mention that some 2003 and 2004 models may also have had a fuel tank drain plug.
It's important to note that attempting to empty the fuel tank by running the engine and using the fuel pump can destroy the pump due to diesel contamination and overheating. Therefore, it is recommended to drop the tank and remove the pump assembly to empty the tank. This process can be challenging, and proper safety precautions should be taken when handling fuel.
One way to make the process of dropping the tank easier is to first siphon out some of the gas to reduce the weight of the tank. This can be done using a siphon pump or a similar tool. Once the tank is dropped, the pump assembly can be removed, and the fuel can be dumped out and the tank cleaned.
In some cases, a small leak in the drain cap at the back of the gas tank may occur, which can be repaired using an adhesive designed for this purpose.

Removing the radiator cap
To remove the radiator cap from your PT Cruiser, you will need to follow a few important steps to ensure your safety and avoid any potential issues. Here is a detailed guide on how to do it:
First, it is crucial to understand that draining fuel from your vehicle's tank can be dangerous due to the flammable nature of fuel and its fumes. Always work in a well-ventilated area, keep a Class B fire extinguisher nearby, and ensure there are no sources of ignition nearby.
Before beginning the process, it is recommended to have approved closed containers ready to store the drained fuel. These containers should be specifically designed for fuel storage to prevent any accidental leaks or spills.
Now, locate the radiator cap on your PT Cruiser. It is typically found on the radiator, which is part of the vehicle's cooling system. The radiator cap is responsible for sealing the cooling system and maintaining the appropriate pressure.
Once you have located the radiator cap, wait for the engine to cool down completely before proceeding. The radiator and cooling system can become extremely hot during operation, and attempting to remove the cap while the system is hot can lead to serious burns. Ensure that the engine has been turned off for a sufficient amount of time to allow for adequate cooling.
After confirming that the engine is cool, you can carefully loosen and remove the radiator cap. It is important to do this slowly and with caution to prevent any hot fluid from being ejected from the radiator.
By following these steps, you can safely remove the radiator cap from your PT Cruiser. Remember to exercise caution and prioritize safety throughout the entire process.

Dropping the tank
Firstly, it is important to note that you will need to siphon out some fuel to reduce the weight of the tank before dropping it. This can be done using a siphon pump, as demonstrated in a video referenced on Allpar Forums. Ensure you have approved fuel containers to hold the removed fuel.
Next, place a floor jack with a wooden board underneath the tank to lower it enough to disconnect the lines. Be cautious when handling the fuel lines, as old and cold plastic can be brittle and may snap. If a line or fitting does snap, replace the entire length of the line.
Now, you can start to lower the tank. You may need to manoeuvre the tank as you lower it to work it past the exhaust. Disconnect the filler hose, being mindful to avoid spilling fuel.
Finally, once the tank is dropped, you can remove the pump assembly and dump any remaining fuel. After this, the tank will need to be cleaned, and the pump replaced.
Please note that this process may vary slightly depending on the year and model of your PT Cruiser. Always refer to a professional mechanic or a service manual for specific instructions for your vehicle.

Replacing the fuel pump
To replace the fuel pump in a PT Cruiser, you must first drain the fuel tank. There is no easy way to do this, and it is important not to turn on the engine to empty the tank, as this will destroy the fuel pump.
Some PT Cruiser models have a fuel tank drain plug, which is pictured on page 4-5 of the Haynes service manual. This is likely to be on the right rear side of the tank, to the right of the fill tube and in front of the coil spring. However, this may only be present on the first batch of 2001 models.
If your PT Cruiser does not have a drain plug, you will need to siphon the fuel or drop the tank. If you choose to siphon the fuel, be sure to store it in approved closed containers, as exposed fuel and fumes are extremely flammable. Use a well-ventilated area with no nearby ignition sources, and keep a Class B fire extinguisher on hand.
If you drop the tank, you will need to place a floor jack with a wooden board to lower the tank enough to disconnect the lines. Be careful not to nick the hoses or wires. The cargo floor panel is double-walled, high-strength steel, and would be very difficult to cut.
Once the tank is empty, you can remove the old fuel pump and install the new one. The fuel pump is located inside the fuel tank, so you will need to lower the tank or cut a hole in the floorboard to access it. Be sure to clean the tank before installing the new fuel pump.

Fixing a leak in the drain cap
Fixing a leaking fuel cap can be done in a few different ways, depending on the severity of the leak and your comfort level with car repairs.
First, it's important to identify the source of the leak. Leaking fuel can be dangerous, so it's best to park your car on solid, flat ground and turn off the engine before attempting any repairs. Check the fuel cap and neck for any scratches, chips, dents, or a deteriorating gasket/o-ring, as these are common causes of leaks.
If the leak is minor, you may be able to simply apply an adhesive or epoxy putty to the affected area to seal it. For example, if there is a small hole in the drain cap, an adhesive like Permatex can be used to stop the leak. Epoxy putty is a simple and efficient solution for cracks and small holes, but for larger holes (over 1-2 inches in diameter), welding may be required.
If the issue is with the fuel neck or gasket/o-ring, you may need to replace these parts. Filing down any scratches or dents on the fuel neck may provide a temporary solution, but it is not a long-term fix. Replacing the fuel neck or gasket/o-ring can be more involved and may require the help of a certified mechanic, especially if welding is required.
Remember to exercise caution when working with fuel, and ensure that the area is well-ventilated. Draining the fuel tank may be necessary before performing certain repairs, and it is crucial to avoid creating any sparks that could ignite the fuel.
