Fuel Pressure Regulator is an important part of Cadillac DeVille which regulates the fuel pressure within the electronic fuel injection system. It is normally installed on the fuel rail and has a spring and diaphragm system that controls fuel delivery, in relation to engine vacuum. When the engine is at idle, the regulator permits the excess fuel to be returned to the tank whereas in the event that the throttle is opened the vacuum created is reduced and this effectively limits the return flow so as to maintain more than adequate pressure for the delivery of fuel. Cadillac DeVille has used pressure reducing types and back pressure types of fuel pressure regulators in the past years. The primary distinction lies in their operation: pressure reducing regulators decrease the inlet pressure as a back pressure regulators keep the inlet pressure constant. regulators are made for improved performance, especially when changes such as big injectors or high capacity fuel pumps are made; they can be tuned to achieve the precise air fuel mixture ratio.
