Chrysler Pt Cruiser Fuel Filter: Diy Replacement Guide

The fuel filter on the Chrysler PT Cruiser is built into the fuel pump module, which is mounted inside the fuel tank. 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 various components. It is recommended to refer to a repair manual or seek assistance from a qualified mechanic to ensure the procedure is carried out safely and correctly.

Relieve the fuel system's pressure

Relieving the fuel system's pressure is a crucial first step when changing your Chrysler PT Cruiser's fuel filter. Here's a step-by-step guide to help you safely complete this task:

Begin by locating the fuel pump fuse in your Cruiser's fuse box. This is usually situated in the engine compartment, often near the battery. Refer to your owner's manual for the exact location if you're unsure. Once located, identify the fuse by its amperage rating, typically noted on the fuse box cover or in the owner's manual.

Remove the fuel pump fuse to disable the fuel pump relay and prevent the pump from activating while you work. This step is essential for your safety and to avoid potential fuel spray and injury. With the fuse removed, turn the ignition key to the 'Run' position, but do not start the engine. Depressing the accelerator pedal slightly for about 10 seconds will help ensure that the fuel pressure is relieved.

You can now crank the engine for a short period, around two seconds, to confirm that the vehicle will not start. This verifies that the fuel pump is indeed deactivated and the pressure is relieved. It is important to never crank the engine for extended periods with the fuel pump fuse removed, as this could lead to potential damage to the engine and fuel system.

After completing these steps, you can be confident that the fuel system pressure has been relieved, and it is safe to proceed with changing the fuel filter. Remember to always exercise caution when working with your vehicle's fuel system, and if you're unsure, seek the assistance of a qualified mechanic.

Drain the fuel tank

To drain the fuel tank of a Chrysler PT Cruiser, first remove the fuel cap and open the hood. Remove the cover on the air filter housing and 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.

Next, 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 gas can or drain pan capable of holding 16 gallons.

Now, disconnect the fuel vapor hose and then loosen the hose clamp for the fuel filler neck hose with a screwdriver. You can then disconnect the hose from the fuel fill pipe.

At this point, you can begin to remove the fuel tank by raising a transmission jack under the tank to support it. If you don't have a transmission jack, you can use a floor jack with a piece of plywood on it to prevent damage to the tank.

Disconnect the fuel filler neck hose

Disconnecting the fuel filler neck hose is a crucial step in changing the fuel filter of a Chrysler PT Cruiser. Here is a detailed, step-by-step guide on how to do it:

Firstly, loosen the hose clamp for the fuel filler neck hose. You can use a screwdriver to do this. Once the clamp is loosened, you will be able to disconnect the hose from the fuel fill pipe. This is an important step as it will allow you to access the fuel pump module, which is mounted inside the fuel tank.

Next, you will need to raise the rear end of the car and support it on jack stands. Place a transmission jack under the fuel tank to support it. If you do not have access to a transmission jack, you can use a floor jack with a piece of plywood on it to prevent any damage to the tank.

Now, you can begin to disconnect the components connected to the fuel tank. Disconnect the EVAP line and fuel supply hose at the quick-connect fitting. Then, disconnect the electrical connector for the fuel pump module. At this point, you should be able to clearly see the fuel filler neck hose.

Finally, carefully disconnect the fuel filler neck hose from the fuel tank. Ensure that you have a gas can or drain pan capable of holding 16 gallons ready to catch any remaining fuel that may spill out of the tank. This step is important to do carefully to avoid any spills or leaks.

By following these steps, you will successfully disconnect the fuel filler neck hose, which is an essential part of changing the fuel filter in a Chrysler PT Cruiser.

Disconnect the EVAP line and fuel supply hose

Disconnecting the EVAP line and fuel supply hose is a crucial step in changing the fuel filter of a Chrysler PT Cruiser. Here is a detailed, step-by-step guide on how to do this:

Firstly, ensure you have the necessary tools and safety equipment. This includes eye protection, gloves, and a jack to raise the car's rear end. Place jack stands under the car for support. Next, relieve the fuel system's pressure by removing the fuel cap and opening the hood. Remove the cover on the air filter housing, and 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 you can begin to access the fuel tank. 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. Ensure it has a capacity of at least 16 gallons. Once the tank is drained, disconnect the fuel vapor hose and loosen the hose clamp for the fuel filler neck hose with a screwdriver. You can then disconnect the hose from the fuel fill pipe.

At this point, you are ready to disconnect the EVAP line and fuel supply hose. Raise a transmission jack under the tank to support it. If you do not have a transmission jack, you can use a floor jack with a piece of plywood on it to prevent damage to the tank. Locate the quick-connect fitting and disconnect the EVAP line and fuel supply hose. Be careful when handling these components, as they are essential to the vehicle's fuel system.

With the EVAP line and fuel supply hose disconnected, you can proceed to the next steps of changing the fuel filter. Remember to work carefully and refer to a repair manual if needed.

Remove the fuel tank

To remove the fuel tank from a Chrysler PT Cruiser, first relieve the fuel system's pressure. Open the fuel tank by removing the fuel cap, then open the hood and remove the cover on the air filter housing. Next, 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, then turn off the ignition and disconnect the negative battery cable.

Now you can begin to remove the fuel tank itself. First, 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 gas can or drain pan capable of holding 16 gallons. Disconnect the fuel vapour hose and then loosen the hose clamp for the fuel filler neck hose with a screwdriver so you can disconnect the hose from the fuel fill pipe.

Raise a transmission jack under the tank to support it. If you only have a floor jack, place a piece of plywood on it to prevent it from damaging the tank. Disconnect the EVAP line and fuel supply hose at the quick-connect fitting. Disconnect the electrical connector for the fuel pump module. Finally, unbolt the tank support straps with a wrench and lower the jack to remove the tank.
