Delphi FP10413 Fuel Injection Pressure Regulator

Fuel Pressure Control for Honda and Acura Applications

Delphi FP10413 is a fuel injection pressure regulator built with a metal body and OE-based engineering. It maintains a 44 psi system pressure and uses a bolt-on mounting design with one push-in inlet and one hose outlet for a direct service replacement on select Honda and Acura fuel systems.

Compatible with 1992-1995 Honda Civic, 1993-1997 Honda Civic del Sol, 1999 Honda Civic, and 1994-2001 Acura Integra applications, this regulator supports consistent fuel delivery in vehicles that rely on stable rail pressure. Delphi FP10413 is a practical choice when replacing a worn or leaking fuel pressure regulator on these platforms.

Key Features

• Fuel injection pressure regulator for air and fuel delivery systems
• Metal construction for durable underhood service
• 44 psi system pressure specification
• One push-in inlet and one hose-style outlet
• Bolt mounting type for secure installation
• No gauge port and non-adjustable design
• OE heritage informed by Delphi’s supplier experience

Detailed Description

The Delphi FP10413 fuel injection pressure regulator is engineered for select Honda Civic, Honda Civic del Sol, and Acura Integra fuel systems where stable pressure is critical to injector performance. Its 16.0 mm inlet port diameter and 6.0 mm outlet port diameter support the specified fuel routing, while the metal housing helps provide consistent service in demanding engine bay conditions. Delphi draws on OE development knowledge to produce aftermarket parts that align with original equipment expectations for fit and function.

This part cross-references Beck/Arnley 158-0316 and Standard Ignition PR489 for the same application.

Common Issues This Part Can Address

• Fuel pressure that is too high or too low at the rail
• Fuel odor or seepage from a leaking regulator body
• Rough idle caused by unstable fuel delivery
• Hard starting related to incorrect fuel pressure
• Rich or lean running conditions tied to regulator wear

Installation Notes and Tips

Verify the inlet and outlet connection style before installation, since this regulator uses a push-in inlet and hose outlet. Confirm the 44 psi system pressure specification against the vehicle’s fuel system requirements, and inspect nearby fuel lines, clamps, and seals for wear before reassembly. Clean mating surfaces and check for leaks after startup.

Quality Assurance

Delphi builds this regulator using OE-based engineering and decades of supplier experience with major automakers. That background is reflected in the part’s material selection, pressure specification, and application-focused design for Honda Civic, Honda Civic del Sol, and Acura Integra fuel systems.
