Nissan 300ZX Fuel Pressure Regulator

The Fuel Pressure Regulator in Nissan 300ZX cars is very crucial as is responsible for determining the amount of fuel supply within the electronic fuel injection. It is fastened directly to the fuel rail and is made up of a spring as well as a diaphragm system, of which controls the fuel flow according to the varying vacuum pressure in the engine. At idle it allows for fuel return based on increased vacuum while at low or zero vacuum during acceleration, it closes this path to allow for enough pressure to service the engines needs. There have been several types of Fuel Pressure Regulators used in the 300ZX over the years to include some adjustable models for fuel modified systems. OEM regulators are usually fixed, and this can be a problem when larger injectors or high volume pumps are used. New generation regulators, sometimes cast in billet aluminum provide provisions for the adjustment of the air/fuel mix ratios as such they can serve both the street car and the race car.
