Delphi FP10401 Fuel Injection Pressure Regulator

Fuel Pressure Control for Ford Applications

The Delphi FP10401 fuel injection pressure regulator helps maintain consistent fuel system pressure for select Ford vehicles. Built with a metal body and OE-focused engineering, it supports stable fuel delivery in applications that require 52 PSI operation.

• Metal construction for fuel system durability
• Fixed-pressure design; not adjustable
• Push-in inlet and outlet connections
• 1 inlet port and 1 outlet port
• Bolt-mounted installation style
• System pressure rating: 52 PSI
• No gauge port

OE-Style Fuel System Performance

Delphi FP10401 is a fuel injection pressure regulator built from the company’s OE heritage and decades of supplier experience with major automakers. It is specified for Ford fuel injection systems that call for 52 PSI, including 1995 Ford Mustang, 1995 Ford E-150 Econoline, 1995 Ford E-150 Econoline Club Wagon, 1995 Ford E-350 Econoline, and 1995 Ford E-350 Econoline Club Wagon. It also covers earlier Ford truck, van, and car applications such as the F-150, F-250, F-350, Bronco, Tempo, and Mercury Topaz across the listed model years. This part number, FP10401, cross-references Standard Ignition PR18 for the same application.

Common Problems This Part Addresses

• Fuel pressure that is too high or too low for the injection system
• Hard starting caused by unstable fuel delivery
• Rough idle from inconsistent rail pressure
• Fuel mixture issues tied to pressure regulation faults
• Driveability concerns on Ford fuel-injected engines

Installation Notes and Fitment Tips

Verify the vehicle’s fuel system specification before installation, since this regulator is listed for 52 PSI applications on select 1995 Ford models and broader 1987-1994 Ford and Mercury coverage. Confirm the inlet and outlet sizes, push-in connection style, and bolt-mount layout match the original part. Use the vehicle’s exact year and model when checking fitment for Ford Mustang, Ford E-Series vans, Ford F-Series trucks, Ford Bronco, Ford Tempo, and Mercury Topaz applications.

Quality Assurance

Delphi builds this regulator with OE experience and supplier knowledge developed through work with leading automakers. That background is reflected in the FP10401’s metal construction and application-specific pressure rating for Ford fuel injection systems.
