This fuel regulator gives a pressure of 3.5 bar and fits directly in place of your current pressure regulator.
Suitable for 928 S4 from 1988 to 1992.
Not suitable for the S2 or S3.
Originally, this fuel pressure regulator is no longer available.
We fitted it with an 8mm hose barb that we had specially made for this purpose. This allows it to fit directly onto the existing fuel hose.
Ageing of the internal diaphragm causes the pressure regulator to leak and fuel to enter the vacuum system. This is not only a fire hazard, but this can also cause the car to drive badly.
