The fuel pressure in a 2006 PT Cruiser should be 58 psi with a variance of around 5 psi. This means that the fuel pressure could be as low as 53 psi or as high as 63 psi. The fuel pressure regulator is part of the fuel pump module, which is located on the top side of the fuel tank, and the fuel system pressure is not controlled by the PCM or engine vacuum.

The fuel pressure should be 58 psi +/- 5 psi
The fuel pressure for a 2006 PT Cruiser should be 58 psi with a variance of +/- 5 psi. This means that the fuel pressure can be as low as 53 psi and as high as 63 psi. This is important because the PT Cruiser's fuel delivery system is designed to deliver a steady fuel pressure within this range.
The fuel pressure regulator is a mechanical device that is not controlled by the PCM or engine vacuum. It is part of the fuel pump module and is located on the top side of the fuel tank. To access the fuel pump and pressure regulator, you need to remove the module.
If you are experiencing driveability problems with your PT Cruiser after installing a Whipple Charger, you may want to consider the PT Fueler™. This is a supplemental pump and precision fuel pressure regulator that can help solve these issues. The PT Fueler™ can also improve fuel economy and power by making better use of the port injectors.
It is important to note that the fuel system is under constant pressure, even with the engine off. Therefore, before testing or servicing any fuel system hose, fitting, or line, you must release the fuel system pressure to avoid possible serious or fatal injury.

The fuel system is under constant pressure
The fuel system of a 2006 PT Cruiser is under constant pressure, even when the engine is off. This means that before testing or servicing any fuel system hose, fitting, or line, the fuel system pressure must be released. Failure to do so could result in serious or fatal injury.
The fuel system pressure regulator is part of the fuel pump module, which is located on the top side of the fuel tank, with access required to view the pump and pressure regulator. The PT Cruiser's fuel delivery system is designed to deliver a steady fuel pressure of 58 psi, with a variance of up to 5 psi. This means the fuel pressure can be as low as 53 psi and as high as 63 psi.
The fuel system uses a non-adjustable pressure regulator that maintains fuel system pressure at approximately 400 ±34 kPa (58 ±5 psi). The spring pushes down on the diaphragm and closes off the fuel return port. The system fuel pressure reflects the amount of pressure required to open the return port. It is important to note that the pressure regulator is a mechanical device and is not controlled by the PCM or engine vacuum.
The PT Cruiser expects a constant 58 (+/- 5) psi fuel pressure at the fuel injector rail. This is achieved through the use of a high-performance fuel pump and a separate fuel regulator near the canister on the firewall.

The fuel system pressure regulator is part of the fuel pump module
The fuel system pressure regulator is an essential component of a vehicle's fuel system. It is responsible for maintaining the correct fuel pressure, ensuring that the fuel injectors receive the right amount of fuel to create a proper fuel and air mixture. This regulation is necessary for the engine's smooth performance and efficiency.
In the context of a 2006 PT Cruiser, the fuel system pressure regulator plays a similar role. While I couldn't find specific information about the fuel pump module in this model, we do know that the fuel pressure should be 58 psi +/- 5 psi. This pressure regulation is critical for the vehicle's performance and fuel efficiency.
The fuel system pressure regulator in the 2006 PT Cruiser is designed to control the upper limit of the fuel pressure. It ensures that the fuel injectors receive fuel at a known rate, maintaining a steady fuel supply even during rapid changes in fuel demand. This regulation helps prevent issues such as misfiring, increased emissions, poor vehicle performance, and reduced fuel efficiency.
To test the fuel pressure in the 2006 PT Cruiser, you need to turn off the ignition and release the fuel system pressure. Then, disconnect the frame rail fuel supply line connector and install the appropriate fuel line adapters or fittings. Finally, install a fuel pressure gauge assembly to measure the pressure.

The PT Fueler is a supplemental pump and precision fuel pressure regulator
The PT Cruiser is a popular car, and like any vehicle, it has its quirks. One issue that has been noted is the fuel pressure regulator and pump. The PT Fueler is a supplemental pump and precision fuel pressure regulator designed to address driveability problems in the PT Cruiser after the installation of a Whipple Charger.
The PT Fueler solves the "lean surge" problem, which is common in supercharged vehicles that use a speed/density fuel calculation. This product improves fuel economy and power by making better use of the port injectors and reducing dependence on the additional injector. The PT Fueler is a great option for those unhappy with their supercharged PT Cruiser's performance.
The stock PT Cruiser fuel delivery system is designed to deliver a steady fuel pressure of 58 psi, with an acceptable range of 53-63 psi. This pressure is maintained by a non-adjustable pressure regulator. However, the PT Fueler, with its precision SX fuel pressure regulator and booster pump, allows for more precise control of fuel pressure. With this upgrade, fuel pressure can be set at 60 psi or higher, and it will track manifold pressure. This means that fuel pressure will be lower at low manifold pressures and higher at high manifold pressures, ensuring the engine always has the optimal fuel pressure for its needs.
The PT Fueler is a great option for those looking to improve the performance of their supercharged PT Cruiser and solve common driveability problems associated with the stock fuel system. It provides better fuel economy, more power, and a more responsive driving experience.

The PT Fueler eliminates the lean surge problem inherent in supercharged vehicles
The PT Fueler is a supplemental pump and precision fuel pressure regulator designed to solve the driveability problems of the Dodge PT Cruiser after the installation of a Whipple Charger. The PT Fueler eliminates the lean surge problem inherent in supercharged vehicles that utilize a speed/density fuel calculation.
The PT Fueler works by making better use of the port injectors and reducing dependence on the additional injector. It also allows for a more precise fuel pressure setting at idle, as well as the ability to track manifold pressure. This results in improved fuel economy and power.
The stock PT Cruiser fuel delivery system uses a non-adjustable pressure regulator that maintains fuel system pressure at approximately 400 ±34 kPa (58 ±5 psi). This means that the fuel pressure can vary between 53 psi and 63 psi. The PT Fueler, on the other hand, allows for a precise fuel pressure setting, which can be set higher than the factory setting if desired.
The PT Fueler is especially useful for PT Cruisers with a Whipple Supercharger as the PT Cruiser uses a speed/density system to control fuel delivery. Unlike a mass air flow system, the speed/density system does not recognize the increase in airflow and tends to lean out. With the PT Fueler, the fuel injectors automatically deliver more fuel as needed, improving the performance and driveability of the vehicle.

Frequently asked questions
The fuel pressure for a 2006 PT Cruiser is 58 psi with a tolerance of around 5 psi either side.
You can check the fuel pressure by removing the plastic hard line that supplies the fuel rail from either end. You will need an inline connection with your fuel gauge to do this.
The fuel pressure regulator is part of the fuel pump module, which is located on the top side of the fuel tank. You will need to remove the module to access the pump and regulator.
No, there is no separate fuel filter.
If your vehicle does not have a Schrader valve, you can let it sit for 12+ hours to allow the pressure to bleed off through the fuel pump and back into the tank. Alternatively, you can slowly release the line from the fuel filter, making sure to wear eye protection.
