The fuel filter in a PT Cruiser is built into the fuel pump module, which is mounted inside the fuel tank. This means that to replace the filter, you must replace the entire pump module. This is a complex process that involves relieving the fuel system's pressure, removing the fuel tank, and disconnecting the battery cable. It is recommended that a repair facility handle this process.

What You'll Learn
The fuel filter is part of the fuel pump
The fuel filter in a PT Cruiser is part of the fuel pump assembly. It is located inside the fuel pump module, which is inside the fuel tank. To replace the fuel filter, you must remove the fuel pump module from the tank. This is a complex process that requires dropping the fuel tank and removing the fuel pump. It is recommended to have a repair facility handle this process.
The fuel pump is cooled and lubricated by the fuel/gas itself. Running the tank very low could cause the pump to burn out. There is no standard maintenance interval for the fuel filter, and it is typically not serviced. However, if the fuel has been contaminated, it may be necessary to drop and clean the fuel tank.
The fuel filter plays a crucial role in ensuring the proper functioning of the fuel pump. By incorporating the filter into the pump assembly, the fuel is filtered before it reaches the engine, preventing contaminants from entering the engine and causing damage. This integrated design ensures that the fuel pump receives clean fuel, optimizing its performance and longevity.
Replacing the fuel filter as part of the fuel pump assembly ensures that the entire module is functioning optimally. The new fuel pump module comes with a fresh fuel filter, guaranteeing efficient fuel filtration and promoting the overall health of the engine. This integrated replacement approach simplifies the maintenance process and ensures the compatibility and seamless operation of the fuel pump and filter as a single unit.
It is important to note that the fuel filter and fuel pump are specific to the PT Cruiser's design. The replacement process may vary for different vehicle models, and it is always advisable to consult a professional mechanic or refer to model-specific repair guides for accurate instructions.

Removing the fuel pump assembly
To remove the fuel pump assembly, first relieve the fuel system's pressure. Remove the fuel cap and open the hood. Then, remove the cover on the air filter housing. Remove the fuel pump relay from the fuse box, which is located behind and below the filter housing. Next, start the engine and let it idle until it stalls. Turn off the ignition and disconnect the negative battery cable.
Now, raise the car's rear end and support it on jack stands. Unscrew and remove the drain cap on the tank and let the fuel drain into a suitable container, such as a gas can or drain pan capable of holding 16 gallons. With the fuel drained, you can proceed to remove the fuel pump assembly, which contains the fuel filter.
It is important to note that the fuel filter is part of the fuel pump module and is not a separate, serviceable part. Therefore, replacing the fuel filter means replacing the entire pump module. This process involves dropping the fuel tank and removing the fuel pump assembly.
Once the fuel pump assembly is removed, you can inspect the fuel filter to determine if it needs to be changed. If the filter is in poor condition, it is likely that the pump also needs to be replaced. Alternatively, you can attempt to clean the filter with a solvent to see if that restores its functionality.

Relieve the fuel system's pressure
To relieve the fuel system's pressure, start by removing the fuel cap and opening the hood. Next, remove the cover on the air filter housing. Then, remove the fuel pump relay from the fuse box, which is located behind and below the filter housing. Start the engine and let it idle until it stalls. Turn off the ignition and disconnect the negative battery cable.
Now that the pressure has been relieved, you can continue with the next steps to change the fuel filter on your PT Cruiser. It's important to note that the fuel filter is part of the fuel pump module, which is mounted inside the fuel tank. To access the fuel pump module, you will need to raise the car's rear end and support it on jack stands. Be sure to place a gas can or drain pan capable of holding 16 gallons under the tank to catch any fuel that may spill.
Once you have removed the fuel pump module, you can inspect the fuel filter to determine if it needs to be replaced. If the filter is in poor condition, it is likely that the pump will also need to be replaced. Remember to handle fuel carefully and take appropriate safety precautions when performing any work on your vehicle's fuel system.
After inspecting or replacing the fuel filter, you can proceed to reinstall the fuel pump module. Ensure that you connect all the necessary lines and hoses, such as the fuel supply hose, filler, vapor, and EVAP lines, as well as the electrical connector. Lower the car off the jack stands and refill the fuel tank. Finally, reconnect the battery cable and fuel pump fuse, and replace the air filter housing.

Drain the fuel tank
To drain the fuel tank of a PT Cruiser, you must first relieve the fuel system's pressure. Remove the fuel cap and open the hood. Remove the cover on the air filter housing, then remove the fuel pump relay from the fuse box located behind and below the filter housing. Start the engine and let it idle until it stalls. Turn off the ignition and disconnect the negative battery cable.
Now, raise the car's rear end and support it on jack stands. Place a gas can or drain pan capable of holding 16 gallons underneath the tank. Unscrew and remove the drain cap on the tank and let the fuel drain.
Once the tank is drained, you can proceed to replace the fuel pump and filter. However, before installing a new pump, it is recommended to inspect the old filter and clean it with solvent to see if it can be reused. If the filter is in poor condition, it is likely that the pump will also need replacing.

Install the replacement fuel pump and filter
To install the replacement fuel pump and filter, first, carefully place the new pump and filter into the fuel tank, being cautious not to damage the float arm or the filter. Next, screw the locknut into place with the water pump pliers, aligning the module with the mark you made earlier. Then, connect the fuel supply hose and electrical connector, using their locking tangs.
After this, use a transmission jack to raise the tank and bolt the straps on. Connect the filler, vapor, and EVAP lines, along with the electrical connector. You can now lower the car off the jack stands. Refill the fuel tank and reconnect the battery cable and fuel pump fuse. Finally, replace the air filter housing.
It is important to note that the fuel filter in a PT Cruiser is built into the fuel pump module, which is mounted inside the fuel tank. Therefore, replacing the filter means replacing the entire pump module. This is a complex procedure that may be best handled by a repair facility, as the fuel tank must be removed.
