OE-Style Design and Fitment

Delphi brings more than a century of OE experience to the FP10049, drawing on supplier knowledge developed with top automakers. This fuel injection pressure regulator is designed for direct replacement use on many Ford F-150, Ford Mustang, Ford Taurus, Ford Explorer, Lincoln Navigator, and Mercury Sable applications listed in the fitment data. This part cross-references Dorman - OE Solutions 800-274 and Standard Ignition PR142 for the same application.

Common Issues This Part Can Address

• Unstable fuel pressure readings in the injection system
• Hard starting caused by incorrect fuel pressure control
• Rich or lean running conditions tied to pressure regulation
• Fuel delivery inconsistency during acceleration or idle
• Fuel system performance problems on Ford, Lincoln, and Mercury vehicles

Installation Notes

Verify the regulator style, port size, and mounting configuration before installation. Fitment includes applications such as Fits 1993-1999 Ford F-150, N/A; Fits 1994-1998 Ford Mustang, N/A; Fits 1998-1999 Lincoln Navigator, N/A; and Fits 1994-1999 Mercury Sable, N/A. Some listings note diaphragm-type or 4-hole-mount configurations, so match the original part number and mounting layout carefully. The Delphi FP10049 is not adjustable and does not include a gauge port.

Quality Assurance

Delphi builds aftermarket parts using OE heritage and application knowledge developed through long-term supplier experience with major automakers. The FP10049 reflects that OE-based approach in its materials, dimensions, and pressure specification.
