Delphi FP10466 Fuel Injection Pressure Regulator

Fuel Pressure Control for OE Fitment

The Delphi FP10466 fuel injection pressure regulator is built for precise fuel system control in select Toyota and Geo applications. It uses a metal body, a push-in inlet, and a hose outlet to match the original-style fuel delivery layout on compatible vehicles.

With a fixed 44 system pressure rating and bolt-on mounting, this regulator is a direct-fit service part for drivers replacing a worn or unstable fuel pressure component on a Toyota Corolla, Toyota Celica, or Geo Prizm.

Detailed Description

The Delphi FP10466 is a fuel injection pressure regulator engineered for consistent fuel delivery control in select import vehicles. Delphi draws on OE heritage and decades of supplier experience, and that background is reflected in the regulator’s metal construction and application-specific design. The inlet measures 11.0 mm with a push-in connection, while the 7.0 mm outlet uses a hose connection for a factory-style fit.

This part cross-references Gates 22826 for the same application. It is a practical replacement choice for owners searching for a fuel injection pressure regulator for 1993-1997 Toyota Corolla, 1994-1997 Toyota Celica, or 1993-1997 Geo Prizm, and it is also identified by part number FP10466.

Common Issues This Part May Address

• Unstable fuel pressure readings in the injection system
• Hard starting caused by incorrect fuel pressure control
• Rich or lean running conditions related to regulator wear
• Fuel delivery inconsistency during acceleration or idle
• Fuel system drivability problems tied to a failing regulator

Installation Notes and Tips

Verify the inlet and outlet connection style, mounting type, and system pressure before installation. Confirm vehicle application by year and model, especially when sourcing a fuel injection pressure regulator for Toyota Corolla, Toyota Celica, or Geo Prizm applications. Inspect adjacent fuel lines and seals for wear before fitting the new regulator, and follow the vehicle service procedure for fuel system depressurization.

Quality Assurance

Delphi builds aftermarket parts using OE experience and supplier knowledge developed through work with major automakers. The FP10466 reflects that OE-focused approach with application-specific dimensions and a fixed-pressure design for the listed vehicles.
