This fuel pressure regulator provides a pressure of 3.5 bar and fits directly in place of your current pressure regulator.
Suitable for 928 S4 models from 1988 to 1992.
Not suitable for the S2 or S3.
The original fuel pressure regulator is no longer available.
We have equipped this one with an 8mm hose barb that we specially had made for this purpose. This allows it to fit directly onto the existing fuel hose.
Due to aging of the internal diaphragm, the pressure regulator can leak and allow fuel into the vacuum system. This is not only a fire hazard but can also cause the car to run poorly.
