Detailed Description

The Delphi FP10388 is a fuel injection pressure regulator designed to maintain consistent fuel pressure in the injection system. Its 44 psi system pressure rating, metal housing, and push-in port design make it a practical OE-style replacement for vehicles that require this specific regulator configuration. This part number is commonly referenced for applications across Chevrolet, Pontiac, Saturn, Buick, Oldsmobile, Cadillac, GMC, and select Isuzu and Acura models. This part cross-references Standard Ignition PR105 for the same application.

Use the Delphi FP10388 when you need a direct replacement fuel pressure regulator for vehicles such as 1985-1993 Chevrolet Camaro, 1985-1992 Pontiac Firebird, or 1990-1993 Chevrolet S10. It also serves other listed applications including 1985-1991 Chevrolet Corvette, 1991-1994 Saturn SL2, and 1996-1997 Isuzu Rodeo.

What It Helps Solve

• Fuel pressure that is too high or too low for the injection system
• Hard starting caused by unstable fuel delivery
• Rough idle from inconsistent regulator operation
• Fuel trim and drivability issues tied to pressure control
• Replacement needs for worn or leaking fuel pressure regulators

Installation Notes and Tips

Verify inlet and outlet port size, mounting style, and system pressure before installation. The FP10388 uses push-in inlet and outlet connections with bolt mounting and does not include a gauge port. Confirm vehicle-specific fuel system requirements for your Chevrolet Camaro, Corvette, S10, or other listed application before replacing the regulator.

Quality Assurance

Delphi builds aftermarket parts using OE experience and knowledge developed through long-term supplier relationships with major automakers. The FP10388 reflects that OE-focused approach in its materials, pressure specification, and application coverage.
