Standard Ignition PR507 Fuel Injection Pressure Regulator

Fuel Pressure Control for Toyota Applications

Standard Ignition PR507 is a new fuel injection pressure regulator for gas systems, built with a steel body and silver finish. It uses a direct mount design with one inlet, one outlet, and an angled nipple orientation for a clean OE-style layout on select Toyota trucks and SUVs.

Compatible With 2010-2019 Toyota Tundra and 2010-2012 Toyota Sequoia applications, this regulator is a direct replacement choice for restoring stable fuel pressure in the injection system. The PR507 includes an O-ring and a caution sheet for service reference.

Key Features

• Standard Ignition PR507 fuel injection pressure regulator
• Direct mount steel construction with silver finish
• Fixed 50 psi operating pressure for gas systems
• Angled nipple orientation for OE-style routing
• Includes O-ring and caution sheet
• One inlet and one outlet

Detailed Description

The PR507 is a non-adjustable fuel injection pressure regulator designed for select Toyota fuel delivery systems. It regulates fuel pressure at 50 psi and uses a direct mounting style to match the original service layout on 2010-2019 Toyota Tundra and 2010-2012 Toyota Sequoia models. Standard Ignition PR507 is a practical replacement when the original regulator is no longer maintaining consistent pressure across the fuel injection system.

This part cross-references Dorman OE Solutions 800-619 for the same application.

Common Issues It Can Address

• Fuel pressure that is too high or too low
• Hard starting related to unstable fuel delivery
• Rough idle caused by inconsistent regulator operation
• Fuel trim concerns tied to pressure control problems
• Driveability issues on Toyota Tundra and Toyota Sequoia fuel systems

Installation Notes and Tips

• Verify the vehicle uses a gas fuel system before ordering.
• Confirm the direct-mount regulator location and angled nipple orientation match the original part.
• Inspect the sealing surface and replace the O-ring during installation.
• Check fuel pressure after installation to confirm proper system operation.
• Follow the caution sheet included with the part during service.

Quality Assurance

Standard Ignition supplies replacement fuel system components for OE-style service applications. PR507 is a new steel regulator built to meet the listed pressure specification and fitment requirements for the confirmed Toyota applications.
