Delphi FP10640 Fuel Injection Pressure Regulator

Fuel Pressure Control for INFINITI G35

Delphi FP10640 is a metal fuel injection pressure regulator built for precise fuel system control on select 2003-2007 INFINITI G35 applications. It uses a push-in inlet, hose outlet, clamp mounting, and a 51 system pressure specification to support consistent fuel delivery.

Built from Delphi OE heritage and engineering knowledge, this fuel injection pressure regulator reflects the company’s long history supplying original equipment to major automakers. The FP10640 is a direct-fit style replacement for the specified INFINITI G35 applications and is also cross-referenced to Gates 24103 and Standard Ignition PR395 for the same application.

Detailed Description

This fuel injection pressure regulator is engineered for fuel delivery systems that require stable pressure control at the rail or line level. For 2003-2007 INFINITI G35 models, the Delphi FP10640 helps maintain the fuel pressure needed for proper injector operation, throttle response, and overall drivability. If you are searching for a fuel injection pressure regulator for INFINITI G35 2003-2007 or a Delphi FP10640 replacement, this part matches the listed application and configuration details.

What It Helps Address

• Fuel pressure that is too high or too low
• Rough idle caused by unstable fuel delivery
• Hard starting related to pressure control issues
• Fuel trim problems from inconsistent regulator performance
• Driveability concerns tied to fuel system pressure regulation

Installation Notes and Tips

Verify the inlet, outlet, mounting style, and system pressure before installation. This regulator uses a push-in inlet, hose outlet, and clamp mount, so the existing fuel line and mounting arrangement must match the listed specifications. Confirm fitment for your exact 2003-2007 INFINITI G35 configuration before replacing the original unit.

Quality Assurance

Delphi draws on more than 100 years of OE experience and original-equipment supply knowledge, and that heritage is reflected in the FP10640 replacement design. This part cross-references Gates 24103 and Standard Ignition PR395 for the same application.
