Cadillac Seville Fuel Pressure Regulator
Cadillac Seville Fuel Pressure Regulator is located at the end of the fuel rail to maintain pressure within a narrow band so that the injectors can deliver the precise mixture that the engine expects. The Fuel Pressure Regulator uses a spring-loaded diaphragm connected to the vacuum port and return line. When you are at idle, manifold vacuum is high. All of the excess fuel can loop back to the tank. As you open the throttle, vacuum drops. This tightens the flow on the return line. This creates a gradual rise in rail pressure for acceleration. Every Cadillac Seville employs a unique design known as a back pressure style valve. This valve differs from the pressure reducing regulators commonly found in hydraulic circuits as it remains normally closed. This occurs until the inlet pressure exceeds the calibrated spring setting. When the spring sticks shut, pressure builds, making the mixture run rich and killing mileage. When a broken spring or internal leak starves the rail, it creates a lean sputter. It is as easy as disconnecting the vacuum hose and watching for a pressure jump or applying hand vacuum, which quickly reveals whether the Fuel Pressure Regulator or another fuel path component is at fault. When engine modifications increase volume beyond stock specs, the original Fuel Pressure Regulator cannot keep up, so enthusiasts often fit a higher capacity Fuel Pressure Regulator to ensure consistent delivery over the entire RPM range, keeping the balanced performance character drivers expect from a Cadillac Seville.
