FUEL PRESSURE REGULATOR ASSEMBLY
The fuel pressure regulator (2) is contained in the fuel tank module. The fuel pressure regulator is a diaphragm relief valve. The diaphragm has fuel
pressure on one side and regulator spring pressure on the other side. The fuel pressure regulator is not vacuum biased. Fuel pressure is controlled by a
pressure balance across the regulator. The fuel system pressure is constant.
