Fuel Pressure Regulator - 4 Bar 1.8T
The fuel pressure regulator maintains a consistent fuel pressure in the fuel lines. When a specific pressure is reached, the regulator releases excess pressure to the return system so it can be reused. A faulty fuel pressure regulator can cause low fuel pressure, high fuel pressure, rich running condition or a delay of building up pressure.
Replace your faulty regulator to keep your engine running strong.
