Replacing Pt Cruiser Fuel Filter: Step-By-Step Guide

The fuel filter in the PT Cruiser is built into the fuel pump module, which is mounted inside the fuel tank. Therefore, to replace the filter, you must replace the entire pump module. This process involves relieving the fuel system's pressure, removing the fuel tank, and then removing and replacing the pump module. It is recommended to have someone knowledgeable about cars perform this task, as it involves dealing with fuel.

The fuel filter is inside the gas tank

To replace the fuel filter in a PT Cruiser, you must replace the entire fuel pump module, as the filter is built into the module. The fuel pump module is mounted inside the gas tank, so to access it, you will need to remove the tank. Here is a step-by-step guide:

Step 1: Prepare the Car

Remove the fuel cap and open the hood. Remove the cover on the air filter housing and locate the fuse box behind and below the filter housing. Remove the fuel pump relay from the fuse box.

Step 2: Relieve the Fuel System's Pressure

Start the engine and let it idle until it stalls. Turn off the ignition.

Step 3: Disconnect the Battery

Disconnect the negative battery cable.

Step 4: Jack Up the Car

Raise the car's rear end and support it on jack stands.

Step 5: Drain the Fuel Tank

Remove the drain cap on the tank and let the fuel drain into a gas can or drain pan capable of holding 16 gallons.

Step 6: Disconnect Hoses and Lines

Disconnect the fuel vapor hose and loosen the hose clamp for the fuel filler neck hose with a screwdriver. Disconnect the EVAP line, the fuel supply hose, and the electrical connector for the fuel pump module.

Step 7: Remove the Fuel Tank

Unbolt the tank support straps with a wrench and lower the jack to remove the tank.

Step 8: Remove the Fuel Pump Module

Squeeze the locking tabs for the fuel supply line and the locking tab for the electrical connector with pliers to disconnect them. Draw an alignment marker on the fuel tank where the fuel outlet connector is pointing so you can correctly line up the new fuel pump module. Unscrew the module's locknut with water pump pliers and remove the module from the tank, being careful not to bend the fuel sending unit float arm.

Step 9: Install the New Fuel Pump and Filter

Install the replacement fuel pump and filter into the fuel tank, ensuring you do not damage the float arm or the filter. Screw the locknut into place with the water pump pliers, using the alignment mark you made.

Step 10: Reattach Components

Connect the fuel supply hose and electrical connector using their locking tangs. Raise the tank back into place with the jack and bolt the straps on. Connect the filler, vapor, and EVAP lines, along with the electrical connector.

Step 11: Finalize

Lower the car off the jack stands, refill the fuel tank, and reconnect the battery cable and fuel pump fuse. Replace the air filter housing.

You'll need to relieve the fuel system's pressure

To relieve the fuel system's pressure, start by removing the fuel cap and opening the hood. Remove the cover on the air filter housing and 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 rear end of the car and support it on jack stands. Unscrew and remove the drain cap on the tank to let the fuel drain into a gas can or drain pan capable of holding 16 gallons. Disconnect the fuel vapor hose and loosen the hose clamp for the fuel filler neck hose with a screwdriver so you can disconnect the hose from the fuel fill pipe.

Place 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 EVAP line and fuel supply hose at the quick-connect fitting. Finally, disconnect the electrical connector for the fuel pump module.

Alternatively, let the vehicle sit for 12+ hours. This will allow the pressure to bleed off through the fuel pump back into the tank.

Disconnect the negative battery cable

To disconnect the negative battery cable of a PT Cruiser, you must first turn off the ignition. Then, open the hood of the car and locate the negative battery cable. It is essential to move the cable away from the battery post to avoid accidental contact. Once you have located the cable, loosen the terminal clamp with a wrench and remove it from the battery post. Ensure you are wearing safety glasses and rubber gloves to prevent any acid injuries in case of a spill.

It is important to note that you should always disconnect the negative battery cable before performing any maintenance or repair work on your vehicle's electrical system. This is because the negative cable is connected to the vehicle's chassis, which acts as a ground. By disconnecting the negative cable, you eliminate the risk of electrical shorts and potential damage to sensitive electronic components.

Additionally, if you are not using a memory saver when disconnecting the battery, you will lose your radio presets and reset the powertrain control module. To prevent this, you can install a memory-saver device according to the manufacturer's instructions before disconnecting the battery. This will help maintain the settings and prevent any inconvenience.

After completing the necessary maintenance or repair work, you can reconnect the negative battery cable by following the same steps in reverse. Ensure that you torque the pinch bolts to 110 inch-pounds for a secure connection.

Raise the car's rear end and support it on jack stands

To raise the rear end of your car, you will need to use a car jack. Place the jack under the car at one of the jacking points, which are usually located near the wheels. Consult your owner's manual if you are unsure of the exact jacking points for your vehicle. Once the jack is in position, slowly raise the car until the rear tires are off the ground.

Once the car is raised, you will need to place jack stands under the vehicle to support it. Jack stands are essential for safety, as they will prevent the car from accidentally falling or slipping off the jack. Place the jack stands on a level surface, ensuring they are securely positioned and able to bear the weight of the vehicle. Lower the car onto the jack stands, making sure they are properly aligned with the vehicle's frame or undercarriage.

With the jack stands in place, you can now remove the jack. Ensure that the car is stable and securely supported by the jack stands before proceeding with any repairs or maintenance work. It is crucial to engage the parking brake and place wheel chocks in front of and behind the front tires to prevent accidental movement of the vehicle.

When you have finished working on your car, use the jack to raise the vehicle slightly off the jack stands. Remove the stands, being cautious not to disturb the stability of the vehicle. Slowly lower the car back to the ground, ensuring it is securely positioned before removing the jack. Remember to reattach the jack to your vehicle or store it in a safe place.

Disconnect the fuel vapor hose and fuel filler neck hose

Disconnecting the fuel vapor hose and fuel filler neck hose is a crucial step in replacing the fuel filter of a PT Cruiser. Here is a detailed, step-by-step guide on how to do this safely and effectively:

Firstly, ensure you have the necessary tools and equipment. For this step, you will need a screwdriver. Before beginning any work, it is important to relieve the fuel system's pressure. This is done by removing the fuel cap, opening the hood, and removing 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. Turn off the ignition and disconnect the negative battery cable.

Now, you can begin to access the fuel vapor hose and fuel filler neck hose. Raise the rear end of the car and securely support it on jack stands. Place a gas can or drain pan capable of holding 16 gallons below the tank and unscrew and remove the drain cap to allow the fuel to drain.

With the fuel drained, you can now disconnect the fuel vapor hose. Loosen the hose clamp for the fuel filler neck hose with your screwdriver. This will allow you to disconnect the hose from the fuel fill pipe. Be careful not to damage any components or connections during this process.

Once the fuel vapor hose and fuel filler neck hose are disconnected, you can proceed to the next steps of replacing the fuel filter. Remember to work carefully and methodically, ensuring all connections are secure and components are protected from damage. Safety should always be a priority when working on automotive systems, especially fuel-related components.
