Delphi FP10405 Fuel Injection Pressure Regulator

Fuel Pressure Control for Honda and Acura

The Delphi FP10405 fuel injection pressure regulator is built for precise fuel system control in select Honda and Acura applications. It uses a metal body, a bolt-on mounting design, and OE-based engineering to help maintain the specified 51 psi system pressure.

Compatible with 1998-2002 Honda Accord, 1998-1999 Acura CL, and 1998 Honda Odyssey, this regulator is a direct-fit service part for vehicles that need stable fuel delivery and consistent injector performance. The Delphi FP10405 is a practical replacement when the original regulator is no longer holding pressure correctly.

Key Features

• Fuel injection pressure regulator for air and fuel delivery systems
• Metal construction for durable underhood service
• Push-in inlet with hose outlet for OE-style routing
• Bolt mounting type for secure installation
• Fixed-pressure design with 51 psi system pressure
• Single inlet and single outlet configuration
• No gauge port and non-adjustable design

Detailed Description

Delphi FP10405 is engineered as a fuel injection pressure regulator for select Honda Accord, Acura CL, and Honda Odyssey models. Delphi draws on OE heritage and decades of supplier experience, and that background is reflected in the fit, materials, and pressure control of this replacement part. The metal housing and OE-style inlet and outlet design support reliable fuel pressure regulation in applications that require a 51 psi system setting.

This part cross-references Beck/Arnley 158-1217 for the same application. If you are replacing a worn regulator on a 1998-2002 Honda Accord, 1998-1999 Acura CL, or 1998 Honda Odyssey, Delphi FP10405 provides the correct style of fuel pressure control for those vehicles.

Common Problems This Part Can Address

• Fuel pressure that is too high or too low
• Hard starting caused by unstable fuel delivery
• Rough idle from inconsistent injector pressure
• Fuel odor or leakage at a failing regulator
• Poor throttle response related to incorrect system pressure

Installation Notes and Tips

Verify the inlet and outlet sizes, mounting style, and system pressure before installation. This regulator uses a push-in inlet, hose outlet, and bolt mounting arrangement, so the fuel lines and mounting point should match the original configuration. Confirm the vehicle application by year and model before ordering the Delphi FP10405.

For fitment, this part is used on 1998-2002 Honda Accord, 1998-1999 Acura CL, and 1998 Honda Odyssey. Matching the original fuel system specification is important for proper operation after replacement.

Quality Assurance

Delphi builds aftermarket parts using OE experience and supplier knowledge developed over many years of original equipment service. The FP10405 reflects that approach with application-specific engineering for Honda Accord, Acura CL, and Honda Odyssey fuel systems.
