Delphi FP10485 Fuel Injection Pressure Regulator

Fuel Pressure Control for OE-Style Repair

The Delphi FP10485 fuel injection pressure regulator is built for precise fuel system control in applications that require stable pressure at the rail. With a metal body, one hose inlet, one bolt outlet, and no gauge port, it matches the layout commonly used in OE-style fuel delivery repairs.

Delphi draws on OE heritage and supplier experience to build aftermarket parts with the same application-focused engineering expected in service replacement work. This regulator is a direct-fit style solution for fuel injection pressure regulator replacement on select Toyota and Lexus fuel system applications, including Toyota Camry and Lexus ES models where the original regulator design matches these specifications.

• Metal construction for fuel system durability
• One hose inlet and one bolt outlet for OE-style routing
• No adjustable setting for factory-calibrated pressure control
• No gauge port for a clean, original-equipment layout
• Delphi FP10485 replacement for fuel injection pressure regulator service

Detailed Application Overview

The FP10485 is a fuel injection pressure regulator used to maintain consistent fuel pressure within the injection system. That consistency supports proper injector operation, stable idle quality, and predictable fuel delivery under changing engine load. This part cross-references Standard Ignition PR495 for the same application. For buyers searching for a Toyota Camry fuel pressure regulator or Lexus ES fuel injection pressure regulator, Delphi FP10485 provides an OE-style replacement built around the original connection style and material specification.

Common Problems This Part Can Address

• Fuel pressure that is too high or too low at the rail
• Rough idle caused by unstable fuel delivery
• Hard starting related to regulator wear
• Fuel odor or leakage at the regulator connection points
• Driveability issues tied to inconsistent injector pressure

Installation Notes and Tips

Verify the inlet and outlet style before ordering, since this regulator uses one hose inlet and one bolt outlet. Confirm the original regulator is non-adjustable and does not require a gauge port. Match the part number FP10485 to the vehicle’s fuel system configuration before installation on Toyota Camry or Lexus ES applications.

Quality Assurance

Delphi builds this replacement part using OE experience and supplier knowledge developed through work with major automakers. That background is reflected in the application-specific design and material selection used in the FP10485 fuel injection pressure regulator.
