Delphi FP10515 Fuel Injection Pressure Regulator

Fuel Pressure Control for OE Applications

The Delphi FP10515 fuel injection pressure regulator is built for precise fuel system control in select Honda, Lexus, and Toyota applications. It uses a metal body, threaded inlet, and hose outlet to support stable fuel pressure at 44 system pressure.

Compatible With 1988-1997 Toyota Camry, 1990-1991 Lexus ES250, 1992-1993 Lexus ES300, 1993-1997 Toyota Land Cruiser, 1995-1997 Honda Accord, and 1996-1997 Lexus LX450. Delphi FP10515 is a direct-fit fuel injection pressure regulator for vehicles that require OE-style fuel pressure regulation.

Key Features

• Fuel injection pressure regulator for air and fuel delivery systems
• Metal construction for durable underhood service
• Threaded 12.0 mm inlet port and 8.0 mm hose outlet port
• Clamp mounting type for secure installation
• Non-adjustable design for factory-style fuel pressure control
• No gauge port
• 44 system pressure specification

Detailed Description

Delphi FP10515 is engineered for fuel injection systems that require consistent pressure regulation across a range of Toyota and Lexus platforms, along with select Honda Accord applications. As an OE-focused supplier with long-standing original equipment experience, Delphi applies production knowledge from factory-level applications to aftermarket replacement parts. This regulator is designed with one threaded inlet, one hose outlet, and a metal housing to match the needs of the original fuel delivery setup.

This part cross-references Dorman OE Solutions 800-227 and Gates 21869 for the same application. Delphi FP10515 is a practical replacement choice when servicing fuel pressure concerns on a 1995-1997 Honda Accord, 1988-1993 Toyota Camry, or 1993-1997 Toyota Land Cruiser.

Common Issues It May Address

• Fuel pressure that is too high or too low
• Hard starting caused by unstable fuel delivery
• Rough idle related to inconsistent injector pressure
• Fuel odor or rich-running symptoms from regulator failure
• Driveability problems tied to worn fuel system pressure control

Installation Notes and Tips

• Verify inlet and outlet port sizes before installation: 12.0 mm inlet and 8.0 mm outlet.
• Confirm the vehicle uses a threaded inlet and hose outlet configuration.
• Inspect fuel lines, clamps, and sealing surfaces during replacement.
• Relieve fuel system pressure before removing the existing regulator.
• Match the application to the listed year and model before ordering.

Quality Assurance

Delphi builds this regulator using OE heritage and manufacturing knowledge developed through supplier relationships with major automakers. The FP10515 is made to support factory-style fuel pressure regulation in the listed applications.
