Reliable Fuel Injection Pressure Regulator for Infiniti G35

The Delphi FP10640 fuel injection pressure regulator is designed to maintain consistent fuel pressure in your Infiniti G35's fuel injection system. Constructed from durable metal, this non-adjustable regulator ensures stable fuel delivery for optimal engine performance.

  • Durable metal construction for long-lasting performance
  • Non-adjustable design for precise factory-set pressure

Product Details and Specifications

The Delphi FP10640 fuel injection pressure regulator is engineered specifically for the Infiniti G35 fuel injection system. Featuring a metal body, this regulator is built to withstand the demands of fuel delivery under pressure. The inlet uses a push-in connection type, while the outlet is designed for hose attachment, facilitating a reliable seal and easy integration with existing fuel lines. With one inlet and one outlet port, the regulator simplifies installation and maintenance. The clamp mounting type secures the regulator firmly in place, reducing the risk of vibration-related issues. This unit is non-adjustable, providing a consistent system pressure of 51 psi, which aligns with the original equipment manufacturer’s requirements for the Infiniti G35.

Compatible Applications and Common Issues Addressed

  • Compatible with Infiniti G35 models requiring a fuel injection pressure regulator
  • Helps resolve inconsistent fuel pressure leading to engine hesitation or stalling
  • Addresses fuel leaks caused by worn or damaged pressure regulators
  • Prevents poor fuel economy due to improper fuel pressure regulation
  • Reduces rough idling and engine performance issues related to fuel delivery

Installation Notes and Tips

When installing the Delphi FP10640 on your Infiniti G35, ensure the fuel system is depressurized before removal of the old regulator. The push-in inlet and hose outlet connections should be inspected for wear or damage and replaced if necessary to maintain a secure seal. Use the clamp mounting type to firmly secure the regulator in place, minimizing vibration and potential disconnections. Since this regulator is non-adjustable, no pressure tuning is required after installation.
