Delphi FP10044 Fuel Injection Pressure Regulator

Fuel Pressure Control for Ford Applications

The Delphi FP10044 fuel injection pressure regulator is built for Ford fuel systems that require stable pressure control and OE-style fitment. It is a metal, bolt-mounted regulator with a 39 psi system pressure rating, a push-in inlet, and a threaded outlet for service on select Ranger, Explorer, and Aerostar applications.

Delphi draws on more than 100 years of OE experience, with engineering knowledge developed alongside top automakers and carried into its aftermarket fuel system parts. The FP10044 is a direct replacement choice for drivers servicing Ford fuel injection pressure regulator applications.

Key Features

• Part number: FP10044
• Fuel injection pressure regulator for air and fuel delivery systems
• Metal construction for fuel system durability
• System pressure rating: 39 psi
• Push-in inlet with threaded outlet
• 1 inlet and 1 outlet
• Bolt mounting type
• No gauge port and not adjustable
• Compatible with select Ford Ranger, Explorer, and Aerostar models

Detailed Description

The Delphi FP10044 is a fuel injection pressure regulator engineered for specific Ford fuel delivery setups that use a push-in inlet and threaded outlet configuration. Its 39 psi system pressure specification makes it a practical replacement for maintaining consistent fuel pressure in the injection system. If you are searching for a Ford Ranger fuel injection pressure regulator, Ford Explorer fuel pressure regulator, or Ford Aerostar fuel system regulator, this part number is a direct reference point for the listed applications. This part cross-references Standard Ignition (e.g., PR35, PR61) for the same application.

What It Helps Address

• Fuel pressure that is too high or too low
• Hard starting caused by inconsistent fuel delivery
• Rough idle related to unstable injector pressure
• Fuel trim issues tied to regulator performance
• Driveability problems on Ford Ranger, Explorer, and Aerostar fuel systems

Installation Notes and Tips

• Verify the inlet and outlet style before installation: push-in inlet and threaded outlet.
• Confirm the vehicle uses a 39 psi regulator specification.
• Check for the correct mounting style and hose/line routing on the existing fuel system.
• Inspect related fuel lines, seals, and connectors for wear before reassembly.
• Use the vehicle service information for the exact Ford Ranger, Explorer, or Aerostar application.

Quality Assurance

Delphi builds aftermarket fuel system components using OE heritage and engineering knowledge developed from supplying top automakers. The FP10044 reflects that OE-focused approach for Ford fuel injection pressure regulator service.
