What You'll Learn
The fuel filter is part of the fuel pump assembly
The fuel filter in a PT Cruiser is part of the fuel pump assembly and is located inside the fuel tank. This means that the fuel filter cannot be replaced in isolation; the whole fuel pump assembly must be replaced.
The fuel pump assembly is comprised of a module that includes the fuel filter inside of it. This is situated inside the fuel tank.
Before replacing the fuel pump assembly, it is important to identify what the issue is. It is recommended that a spark test and a fuel pressure test are carried out.
Fuel filters are not normally serviced and there is no scheduled maintenance interval for them. However, if fuel contamination is suspected, the strainers (socks) and fuel pressure regulators (FPR) should be replaced.
In some cases, the fuel tank may need to be dropped and cleaned out. If the fuel has been contaminated, it is important to check for 'sediment' inside the fuel rails, as this has been found in some cars.

It's located inside the fuel tank
The fuel filter on a PT Cruiser is located inside the fuel tank. It is part of the fuel pump assembly and is mounted inside the fuel pump module. This means that to replace the fuel filter, you must drop the tank and remove the entire fuel pump assembly.
The fuel filter cannot be serviced or replaced on its own. If you suspect a fuel contamination issue, you may need to replace the entire fuel pump module, which includes the fuel filter. This is because fuel filters are not typically serviced and there is no scheduled maintenance interval for them.
It is important to note that running the fuel tank very low could cause the pump to burn out. This is because the pump is cooled and lubricated by the fuel itself, so running the tank low can lead to overheating and potential damage.
If you are experiencing issues with your fuel system or suspect contamination, it is recommended to consult a professional mechanic or a specialist for guidance and repair. They will be able to properly diagnose and address any issues with your PT Cruiser's fuel system, including the fuel filter and pump.

You must drop the tank to replace the fuel filter
The fuel filter on a PT Cruiser is part of the fuel pump assembly, which is located inside the fuel tank. This means that to replace the fuel filter, you must drop the tank.
First, locate the fuel tank and fuel pump assembly. The fuel tank is typically located at the rear of the vehicle, and the fuel pump assembly is inside the tank.
Next, you will need to remove the fuel pump assembly. This may involve disconnecting electrical connectors, fuel lines, and other components that are attached to the assembly. Be sure to have a container ready to catch any fuel that may spill during this process.
Once the fuel pump assembly is removed, you can access the fuel filter. It is important to note that you cannot just replace the fuel filter; you will need to replace the entire fuel pump. This is because the fuel filter is incorporated into the fuel pump and cannot be separated.
Install the new fuel pump with the built-in fuel filter, and then reconnect all the components that were previously disconnected. Be sure to properly seal all connections to prevent any fuel leaks.
Finally, refill the fuel tank and start the engine to test the new fuel filter and pump. Ensure that there are no leaks and that the engine is running smoothly.
It is recommended that this job be performed by a qualified repair facility as it involves handling the fuel tank and fuel system components.

The pump is cooled and lubricated by the fuel
The fuel filter on a PT Cruiser is part of the fuel pump assembly, located inside the fuel tank.
Fuel pumps are submerged in fuel at the bottom of the tank, which cools the pump. Liquid fuel, without the presence of oxygen, is not flammable, so surrounding the fuel pump with fuel reduces the risk of fire.
Fuel injected engines use electric fuel pumps mounted inside the fuel tank, which transfer fuel from the tank to the carburetor or fuel injector. The fuel is then forced through a check valve and into the fuel injector nozzle.
Fuel is also used to lubricate the pump, preventing oil from contaminating the fuel. However, some people choose to use fuel additives to lubricate the pump and reduce noise. For example, Marvel Mystery Oil can be used in an EFI, and Lucas Fuel Treatment can be used every 3-4 fill-ups. It is important to only use gasoline or a proven fuel system cleaner in your fuel tank.

No secondary fuel filter on the car
The fuel filter on a PT Cruiser is part of the fuel pump assembly and is located inside the fuel tank. This means that there is no separate, secondary fuel filter on the car. The fuel filter cannot be serviced on its own and is considered a non-serviceable part. If there is an issue with the fuel filter, the entire fuel pump module will need to be replaced.
The fuel filter is located inside the fuel pump module, which is situated at the bottom of the fuel tank. This is because the pump is cooled and lubricated by the fuel/gas itself. Running the tank very low on fuel could cause the pump to burn out as it will no longer be sufficiently cooled.
As fuel filters are not normally serviced, there is no scheduled maintenance interval for them. However, if fuel contamination is suspected, the strainers (socks) and fuel pressure regulators (FPR) should be replaced. In some cases, the fuel tank may need to be dropped and cleaned out, or even replaced if the contamination has caused significant issues.
It is worth noting that fuel injectors have fine screens, and the stock in-tank strainer is 10 microns, which will not allow water to pass through. However, it is possible for this strainer to become blocked by water.
