Direct replacement for the OEM Bosch fuel pressure regulators on the Porsche 924s, 944, 944S, S2 and Turbo and many other makes and models.  Most of these regulators are original and now nearly 40 years old.  They are prone to leaking or failure and can cause all sorts of running and tuning issues.

For the Turbo team, if you need to increase fuel pressure to get more fuel out of the system to match your preferred tuning chip, the adjustable regulator makes this a simple task.

To suit the lower operating fuel pressure of the Motronic, we use an adjustable fuel pressure regulator.  This simple and elegant design is a direct fit to the factory fuel system.

• Easily replaceable fuel pressure regulator.
• Direct O-ring fit to factory fuel rail
  
• Hose barb return line fitting

The adjustable fuel pressure regulator has been tested with Bosch 044 fuel pumps and work well for this higher flow rate. The upper limit of fuel flow rate has not been tested.

What is Included in the kit:

Additional Notes:

** Other fittings and options such as fuel pressure sensors, or fuel pressure gauges available upon request.

** On some cars, the fuel pressure regulator may have been changed to a different version, please check the installed regulator and make sure it is the same. As the installed regulator and hoses may not match the car and engine model and year referenced above.

** The fuel pressure regulator needs to be adjusted and set on the car after installation to ensure the operating conditions meet the factory specifications.  A fuel pressure gauge and fittings to adapt to the factory fuel rails is required to be able to complete this procedure.  The regulators are not shipped pre-set to the 2.5bar operating pressure.

** We also stock the 944 fuel pressure damper as a direct replacement.
