What is the purpose of the fuel pressure regulator in Ford Bronco EFI models?

EFI models maintain constant fuel pressure from the fuel pressure regulator by causing resistance beyond the injectors, thus allowing some of it to go back to the tank. It can vary its restriction through engine vacuum, a diaphragm, and a spring as engine requirements change. Additionally, when the fuel pump is not running, the restrictor closes very fast and acts like a check valve thereby aiding quick engine restarts. For proper functioning, fuel flow should be unblocked, an open return path must exist along with a dependable vacuum signal. Failure can result in overpressure or underpressure which are caused by contamination or valve malfunctions.

Ford Bronco Fuel Pressure Regulator

The Fuel Pressure Regulator as applied to Ford Bronco cars plays an important role within the electronic fuel injection systems sustaining normal fuel pressure. It is often installed on the fuel rail and works on the basis of a spring and diaphragm assembly. By joining with the engine vacuum and the fuel return line the regulator controls the fuel flow according with the engine's demand of it; at idle the extra fuel, which is not needed, is returned to the tank while during acceleration the fuel supply is limited. Several models of Fuel Pressure Regulators have existed for Bronco through the years, namely adjustable ones for modified systems and static ones for returnless systems. Pertaining to their functioning, OEM regulators are mostly non-adjustable which becomes a drawback while tuning parts such as injector or fuel pump. Whereas OEM components provide only improved power and pay, components provide flexibility and fine-tuning for the specific ratio of air to fuel.
