Detailed Description

Delphi FP10416 is a fuel injection pressure regulator engineered for vehicles that require stable fuel delivery at the specified system pressure. Delphi draws on OE heritage and decades of supplier experience to produce aftermarket parts that reflect original-equipment design knowledge. This regulator is a direct-fit style component for 1997 Acura CL, 1994-1997 Honda Accord, 1995-1997 Honda Odyssey, and 1996-1997 Isuzu Oasis applications.

This part cross-references Gates 22869 for the same application. The Delphi FP10416 is also referenced by part number FP10416 in catalog listings, making it easier to verify the correct fuel injection pressure regulator for your vehicle.

What It Helps Address

• Fuel pressure that is too high or too low
• Rough idle caused by inconsistent injector fuel supply
• Hard starting related to unstable fuel pressure
• Fuel delivery issues that affect acceleration and throttle response
• Driveability problems in Honda Accord, Honda Odyssey, Acura CL, and Isuzu Oasis fuel systems

Installation Notes and Tips

Confirm inlet and outlet port sizes before installation: 16.0 mm push-in inlet and 8.0 mm hose outlet. Verify the bolt-mount location and compare the original regulator to FP10416 before removal. Clean the surrounding fuel system area, inspect hoses and seals for wear, and follow factory service procedures for depressurizing the fuel system before service.

Quality Assurance

Delphi builds this regulator using OE experience and supplier knowledge developed through work with major automakers. The FP10416 reflects that OE-based engineering approach for dependable fuel pressure control in the listed applications.
