How to service the Fuel Pressure Regulator on Toyota Sequoia?

Service of the Fuel Pressure Regulator starts with the removal of the vacuum hose from the intake air resonator and fuel return hose from the pressure regulator after placing the shop towel underneath the regulator. The service starts by extracting two bolts followed by pressure regulator removal while separate O-rings need removal. The installation process requires application of gasoline on a new O-ring before putting it onto the pressure regulator. Use a clockwise and counterclockwise movement of the pressure regulator as you install it onto the delivery pipe and tighten the 2 bolts to 7.5 N.m (80 kgf.cm, 66 in.lbf). After restoring both connections you should check for fuel leaks. The vacuum hose should connect to the intake air resonator and the fuel return hose should join the pressure regulator.

How to Properly Install a Fuel Pressure Regulator with a Pulsation Damper on Toyota Sequoia?

The 2UZ-FE engine requires proper placement of its differently shaped gaskets before installing new gaskets and the fuel main hose with the attached fuel pressure pulsation damper assembly. Follow instructions for Special Service Tools: 09612-24014 and 09617-24011 when using them to tighten the union bolt until it reaches 33 Nm (340 kgf-cm, 24 ft-lbf) torque. According to the installation procedure, the correct torque value without the Special Service Tool is 39 Nm (398 kgf-cm, 29 ft-lbf). The correct torque can be achieved through the use of a 300 mm (11.81 in.) torque wrench with a Special Service Tool having 30 mm (1.18 in.) dimensions when the tools remain parallel to one another when in use. Finally, inspect for fuel leaks.

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.
