Engine & Performance Warehouse PR307 Fuel Injection Pressure Regulator

The Engine & Performance Warehouse PR307 is a fuel injection pressure regulator designed to ensure precise fuel metering for optimal engine performance and fuel efficiency. This direct-fit replacement component maintains proper fuel system pressure to deliver the correct air/fuel mixture under all operating conditions.

Key Features:

• Stock replacement pressure regulator for reliable fuel system operation
• Includes vacuum reference port for manifold vacuum compensation
• Precision-engineered to maintain proper fuel pressure specifications
• Prevents overly rich fuel mixtures caused by excessive pressure
• Machined finish for durability and precise fitment

Defective fuel pressure regulators often develop excessive pressures that create rich air/fuel mixtures, reducing mileage and performance. A failing regulator diaphragm can also leak fuel vapors into the intake manifold through the vacuum hose, further enriching the mixture. This replacement regulator restores proper fuel system function to maintain peak engine efficiency.
