Toyota Sequoia Fuel Pressure Regulator

The Fuel Pressure Regulator is used by the Toyota Sequoia automobiles because they have an electronic fuel injector. It is usually located on the fuel rail and is controlled by a spring and a diaphragm type system. The regulator is connected to the engine vacuum and to the fuel return line; it responds to the engine needs and let more fuel return to the tank when the engine is idling and when more fuel is required during acceleration. Different years of Sequoia use different types of Fuel Pressure Regulators; some of them include adjustable types if the fuel system is modified in some way. Most OEM regulators are non-adjustable, meaning that they may hinder performance when, for example, larger injectors or high volume pumps are fitted. Newer versions of regulators are usually constructed from billet aluminum and provide on the fly adjustment in addition to fine tweaking of air/fuel ratios from highway cruising to the track use.
