Airtex Fuel Injection Pressure Regulator

The Airtex Fuel Injection Pressure Regulator (also called a fuel pressure regulator) helps keep fuel pressure at the injectors steady on fuel-injected engines. It adjusts pressure as engine load and intake manifold vacuum change. This helps the engine get the right amount of fuel across different driving conditions.

Key Features:

• Replacement fuel pressure regulator for fuel-injected gasoline engines
• Helps maintain consistent fuel pressure for smooth starting, steady idle, and responsive acceleration
• Returns excess fuel to the tank through the return line, which helps control rail pressure
• Made for a direct-fit replacement without modifying the fuel system
• Backed by Airtex, a long-established brand in fuel system components

A worn or failing regulator can cause symptoms such as rough running, hard starting, poor fuel economy, black smoke, or fuel in the vacuum line. Replacing it restores correct fuel delivery and helps the engine run efficiently. Each part number in this product line is engineered for its specific application.
