Delphi FP10424 Fuel Injection Pressure Regulator

Fuel Pressure Control for Nissan Applications

The Delphi FP10424 fuel injection pressure regulator is built for precise fuel system control in select Nissan trucks and SUVs. It uses a metal body, a push-in inlet, and a hose outlet to support stable fuel pressure in the injection system.

Compatible with 1998-2004 Nissan Frontier and 2000-2004 Nissan Xterra applications, this regulator is specified for 44 system pressure and a bolt-on mounting style. Delphi draws on OE heritage and supplier experience to build aftermarket parts with factory-level design knowledge.

Key Features

• Fuel injection pressure regulator for air and fuel delivery systems
• Metal construction for durable fuel system service
• Push-in inlet and hose outlet for the specified fuel line connections
• Bolt mounting type for secure installation
• 44 system pressure specification
• Non-adjustable design
• Fits Nissan Frontier and Nissan Xterra applications
• Delphi FP10424 part number for direct reference

Detailed Description

The Delphi FP10424 is a fuel injection pressure regulator engineered for select Nissan Frontier and Nissan Xterra models. It is designed with one inlet and one outlet, an 11.0 mm inlet port diameter, and an 8.0 mm outlet port diameter. The regulator’s metal construction and OE-informed design support consistent fuel pressure management in the injection system, helping maintain proper fuel delivery under normal operating conditions. This part cross-references Standard Ignition PR246 for the same application.

For buyers searching for a 1998-2004 Nissan Frontier fuel injection pressure regulator or a 2000-2004 Nissan Xterra fuel pressure regulator, Delphi FP10424 provides a direct replacement option with the listed connection style and pressure specification. The part number FP10424 is also useful when verifying the correct regulator against service information or existing component markings.

What It Helps Address

• Fuel pressure that is outside the specified 44 system pressure
• Hard starting caused by inconsistent fuel delivery
• Rough idle related to unstable injection pressure
• Fuel system performance issues tied to a worn regulator
• Incorrect fuel pressure control in Nissan Frontier and Xterra applications

Installation Notes and Tips

Confirm the inlet and outlet connection style, port diameters, and mounting type before installation. Verify the vehicle application against the existing regulator and service data for your Nissan Frontier or Nissan Xterra. Because this regulator is not adjustable, system pressure should be checked after installation to confirm proper operation.

Quality Assurance

Delphi builds aftermarket fuel system parts using OE experience and knowledge developed through supplier relationships with major automakers. The FP10424 reflects that OE-based engineering approach for fuel pressure regulation in the specified Nissan applications.
