What It Does:

The fuel pressure regulator maintains consistent fuel pressure by controlling the amount of fuel returned to the tank. A properly functioning regulator ensures precise fuel metering for optimum mileage and performance. Defective regulators can cause excessive fuel pressure leading to a rich air/fuel mixture, which reduces fuel economy and performance. If the regulator diaphragm fails, fuel can leak into the intake manifold through the vacuum line, causing severe running issues.
