Delphi FP10410 Fuel Injection Pressure Regulator

Fuel Pressure Control for Honda Applications

The Delphi FP10410 fuel injection pressure regulator is built for precise fuel system control in select Honda applications. It uses a metal body, a push-in inlet, and a hose-style outlet to support stable fuel pressure at a 44 psi system pressure rating.

Compatible with 1996-2000 Honda Civic, 1996-1997 Honda Civic del Sol, and 1999-2001 Honda CR-V, this regulator is a direct-fit option for common fuel delivery service needs. Delphi draws on OE engineering experience to produce aftermarket parts with factory-style fit and function.

Key Features

• Delphi FP10410 fuel injection pressure regulator
• Metal construction for fuel system durability
• Push-in inlet and hose outlet configuration
• Single inlet and single outlet design
• Bolt-on mounting type
• 44 psi system pressure specification
• No gauge port and non-adjustable design

Detailed Description

The FP10410 is a fuel injection pressure regulator designed to maintain consistent fuel pressure in the injection system. Its 16.0 mm push-in inlet and 6.0 mm hose outlet support the original-style connection layout used on select Honda Civic, Honda Civic del Sol, and Honda CR-V models. Delphi’s OE background is reflected in the part’s material selection and application-specific design.

This part cross-references Dorman - OE Solutions 800-390 for the same application.

What It Helps 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 smell or rich-running symptoms from regulator failure
• Driveability issues tied to worn fuel system components

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 and match the part to the vehicle’s fuel system layout on the Honda Civic, Civic del Sol, or CR-V application listed above.

For best results, inspect nearby fuel hoses and seals during service and replace any damaged components before reassembly.

Quality Assurance

Delphi builds this regulator using OE experience developed through long-term supplier relationships with major automakers. That heritage supports consistent fitment and fuel system performance for the FP10410.
