A direct replacement for the OEM Bosch fuel pressure regulators on the Porsche Carrera 3.2 1983-1989 and early 928 (non CIS) 1980-1986 and some 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. They are easy to replace, albeit a little bit fiddly being at the front of the manifold for the 3.2.
To suit the lower operating fuel pressure of the 3.2 Motronic, we use an adjustable fuel pressure regulator. This simple and elegant design uses steel O-Ring boss sealing adapters to the manifold.
- Easily replaceable fuel pressure regulator.
- Spare outlet for fuel pressure gauge or sensor.
The adjustable fuel pressure regulator has been tested with Bosch 044 fuel pumps, but the upper limit of fuel flow rate has not been tested.
We offer this regulator in two versions. Version 1 is the standard adjustable regulator that can be used on all models referenced below. Version 2, is a fixed 3.8 bar regulator version. This is a direct replacement for the early '87 928's that use the early model regulator design, but with a higher pressure. This can also be used on the other models if the chip or ECU has been tuned for higher fuel pressure.

For the 2.5 Bar fuel pressure cars, this kit must use the adjustable fuel pressure regulator as Bosch does not produce a standard 2.5bar pressure regulator in this form. We can also provide fixed fuel pressure regulators.

Additional Notes:
** 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 can also provide a solution for early 944 replacing Porsche part number 94411019801, Bosch part number 0280160214, 0280160216, 0280160215, 0280150105, BMW E23/E24 635 / 735 / 745, Citroen CX, Fiat 124, Jaguar XJ, Volvo 240 / 340 And others.
** Please compare your original factory part number to those listed above. Sometimes these have been changed from the original installed units on the vehicle by previous owners or workshops.
