Hold fuel pressure steady at the injectors with the Standard Ignition Fuel Injection Pressure Regulator PR461, a new, return-type regulator that installs as a direct-fit replacement for the 2008-2011 and 2013-2021 Lexus LX570 (V8-5.7L), 2014-2018 Toyota Land Cruiser (V8-5.7L), 2008-2010 Toyota Sequoia (V8-5.7L), 2011 Toyota Sequoia (V8-4.6L), and 2007-2012 Toyota Tundra (V8-5.7L). It's tuned for Toyota/Lexus gasoline fuel-delivery systems.
- Return-type, adjustable design: a single inlet and a single outlet with an angled nipple, plus an included reference port.
- Regulates injector fuel pressure: maintains the pressure supplied to the injectors and routes excess fuel back to the tank.
- Durable materials: corrosion-resistant, wear-resistant construction with seals designed to help prevent leaks.
- Validated: engineering process includes 200+ hours of vibration testing plus 1000+ hours of extreme hot- and cold-temperature and on-vehicle testing.
- In the box: includes an O-ring and a caution sheet.
The fuel pressure regulator controls the pressure delivered to the fuel injectors for consistent metering. If a failing regulator is the cause of hard starting, rough running, or poor throttle response, this unit replaces it. Diagnose the cause before replacing.
