Fuel Pressure Control for OE-Style Repair

Standard Ignition PR151 is a fuel injection pressure regulator built for precise fuel delivery and stable engine performance. It is application specific for the listed vehicles, with a fit and form intended to match the original design on many 1982-1986 Buick, Chevrolet, Cadillac, GMC, Oldsmobile, and Pontiac applications.

For drivers searching for a fuel injection pressure regulator diaphragm kit for a 1985 Chevrolet S10, 1984-1986 Pontiac Fiero, or 1982-1986 Buick Century, PR151 provides a direct replacement path for common fuel pressure control issues.

Key Features

• Precision engineered fuel injection pressure regulator for proper fuel delivery
• Application-specific design for the listed vehicle fitments
• Robust construction for greater resistance to leakage
• Designed to address original equipment failure patterns
• Includes instruction sheet and caution sheet
• Gas fuel type application
• Operating pressure: 13 psi

Detailed Description

Standard Ignition PR151 is a fuel injection pressure regulator for gas-powered fuel systems that require controlled pressure at 13 psi. The regulator is engineered to help maintain consistent fuel pressure, which is critical for drivability, throttle response, and overall engine performance. Its application-specific design supports a proper fit on vehicles such as the Chevrolet Camaro, Pontiac Firebird, and Oldsmobile Cutlass Ciera, along with other listed Buick, Cadillac, Chevrolet, GMC, Oldsmobile, and Pontiac models.

This part cross-references Gates 21730 for the same application. Standard Ignition PR151 is also associated with OE and aftermarket references including 2-1730 and 17064942.

What It Helps Fix

• Fuel pressure that is too high or too low
• Hard starting caused by unstable fuel delivery
• Rough idle related to regulator diaphragm wear
• Fuel leakage at the pressure regulator assembly
• Poor engine performance from inconsistent fuel control

Installation Notes and Tips

Review the included instruction sheet and caution sheet before installation. Confirm the vehicle’s fuel system requirements and match the listed fitment exactly, especially on 1982-1986 Buick Century, 1984-1986 Pontiac Fiero, and 1985 Chevrolet S10 applications. Clean the surrounding fuel system components before service and verify that the regulator is installed in the correct fuel injection location for the application.

Quality Assurance

Standard Ignition designs this regulator with application-specific engineering and a leakage-resistant construction approach to support reliable fuel system repair. It is built to replace original equipment units that fail from known pressure-control issues.
