Delphi FP10472 Fuel Injection Pressure Regulator

Fuel Pressure Control for Mitsubishi Applications

The Delphi FP10472 fuel injection pressure regulator is built for precise fuel system control in select Mitsubishi applications. It uses a metal body, a bolt-on mounting design, and OE-based engineering to help maintain the specified 49 psi system pressure.

Compatible with 1995-2002 Mitsubishi Montero and 1997-2004 Mitsubishi Montero Sport, this regulator is a direct-fit service part for fuel injection system repair. The FP10472 is a practical choice when you need stable fuel delivery and consistent pressure regulation.

Detailed Description

Delphi FP10472 is a fuel injection pressure regulator engineered for Mitsubishi Montero and Mitsubishi Montero Sport fuel systems. Delphi draws on OE supplier experience to build aftermarket parts with factory-style fit and function, and this regulator follows the original pressure specification of 49 psi for consistent fuel delivery. The FP10472 part number is commonly searched for Mitsubishi Montero fuel pressure regulator replacement and Mitsubishi Montero Sport fuel injection pressure regulator service.

This part cross-references Beck/Arnley 158-0552 and Gates 23038 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 pressure regulation issues
• Fuel mixture problems tied to inconsistent injector pressure
• Driveability concerns in Mitsubishi Montero and Montero Sport models

Installation Notes

Verify inlet and outlet port sizes before installation: 16.0 mm push-in inlet and 6.0 mm hose outlet. Confirm the bolt-mount location and system pressure specification match the vehicle before replacing the original regulator. Use clean fuel system practices during service to reduce contamination in the injection system. The FP10472 is a direct replacement-style component for the listed Mitsubishi applications.

Quality Assurance

Delphi builds this regulator using OE heritage and application knowledge developed through long-term supplier experience with major automakers. That background is reflected in the FP10472’s factory-style construction and pressure specification for Mitsubishi fuel injection systems.
