Delphi FP10016 Fuel Injection Pressure Regulator

Fuel Pressure Control for OE-Style Repair

The Delphi FP10016 fuel injection pressure regulator is built for precise fuel system control in a wide range of GM, Honda, and Isuzu applications. With metal construction, push-in inlet and outlet connections, and clamp mounting, it is a direct-fit style replacement for vehicles that need stable fuel pressure at the rail.

Delphi brings OE heritage and supplier experience to this aftermarket fuel injection pressure regulator, helping support consistent fuel delivery on applications such as the Chevrolet Camaro, Pontiac Firebird, and Honda Passport.

Key Features

• Metal construction for fuel system durability
• Push-in inlet and push-in outlet for OE-style connection points
• Clamp-mounted design for secure installation
• Single inlet and single outlet layout
• No gauge port and non-adjustable configuration
• Designed for applications using stainless steel and nylon fuel rails where specified
• Delphi FP10016 fuel injection pressure regulator for select import and domestic vehicles

Application Details

This fuel injection pressure regulator is used to maintain proper fuel pressure at the rail, which is critical for consistent injector performance and drivability. It is listed for 1995-2002 Chevrolet Camaro, 1995-2002 Pontiac Firebird, 1999-2002 Honda Passport, 1999-2004 Isuzu Rodeo, 1999-2002 Isuzu Trooper, and other select Acura, Buick, Cadillac, Oldsmobile, and Isuzu models. This part cross-references Standard Ignition PR123 and PR129 for the same application.

What It Helps Address

• Fuel pressure that is too high or too low at the rail
• Hard starting caused by unstable fuel delivery
• Rough idle or hesitation related to pressure regulation
• Fuel trim issues tied to inconsistent injector supply
• Drivability complaints on vehicles with worn regulator components

Installation Notes

Verify fuel rail style before installation, especially on applications noted for stainless steel and nylon fuel rails. Confirm the inlet diameter, outlet diameter, and clamp-style mounting arrangement match the original part. Because this regulator is non-adjustable and has no gauge port, it should be installed as an OE-style replacement rather than a tunable component.

Quality Assurance

Delphi builds this part using OE experience gained from supplying major automakers, with aftermarket engineering informed by original equipment knowledge. The FP10016 is designed to meet the fitment and functional requirements of the listed applications.
