The Engine & Performance Warehouse PR363 is a stock replacement fuel pressure regulator designed to restore proper fuel system operation and ensure your engine receives precisely metered fuel delivery for optimal performance and mileage. This regulator maintains correct fuel pressure to prevent common fuel system issues that can rob your vehicle of efficiency.

Key Features:

• Stock replacement design for direct-fit installation
• Maintains proper fuel pressure for optimal air/fuel mixture
• Prevents overly rich fuel conditions that reduce mileage and performance
• Restores fuel system pressure to factory specifications
• Stock inlet and outlet attachments for bolt-on replacement

Defective fuel pressure regulators commonly develop excessive pressures that create an overly rich air/fuel mixture, negatively impacting fuel economy and engine performance. A failing regulator with a leaking diaphragm can allow fuel to enter the intake manifold through the vacuum hose, causing extremely rich running conditions. The PR363 replaces your worn or failed original unit to restore proper fuel system function.
