Standard Ignition PR154 Fuel Injection Pressure Regulator

Fuel Pressure Control for Metro, Swift, and Firefly

Standard Ignition PR154 is a fuel injection pressure regulator diaphragm kit for gas applications that require stable fuel delivery and consistent engine performance. It is application-specific for the listed Chevrolet Metro, Pontiac Firefly, Geo Metro, Suzuki Swift, and Chevrolet Sprint fitments.

Key Features

• Diaphragm-style fuel injection pressure regulator service part
• Designed for gas fuel systems
• Operating pressure range: 3-7.5 psi
• Application-specific fitment for listed Metro, Swift, Firefly, and Sprint vehicles
• Robust sealing design to help resist leakage
• Includes caution sheet

Detailed Description

The Standard Ignition PR154 is engineered to restore proper fuel pressure regulation in compatible fuel injection systems. By maintaining the specified pressure range, this fuel injection pressure regulator diaphragm kit helps support consistent injector delivery and smoother engine operation. It is a direct-fit service part for select Chevrolet Metro, Pontiac Firefly, Geo Metro, Suzuki Swift, and Chevrolet Sprint applications, including 1987-1997 Chevrolet Sprint, 1989-1997 Geo Metro, 1989-1994 Suzuki Swift, 1991 and 1994-1999 Pontiac Firefly, and 1992 and 1998-2000 Chevrolet Metro.

This part cross-references Gates 21030 and 21810 for the same application. Standard Ignition PR154 is built to address common regulator diaphragm wear and leakage concerns while matching the original application requirements.

What It Helps Address

• Fuel pressure that is outside the specified 3-7.5 psi range
• Hard starting caused by inconsistent fuel delivery
• Rough idle related to unstable fuel pressure regulation
• Fuel leakage at a worn regulator diaphragm
• Poor engine performance from incorrect injector fuel supply

Installation Notes and Tips

Verify the vehicle year, make, and model before installation. Confirm that the fuel system is gas and that the regulator specification matches the listed operating pressure range. Follow the included caution sheet and inspect related fuel system components for wear, contamination, or leakage before reassembly. For fitment searches, this part is commonly referenced as a fuel injection pressure regulator diaphragm kit for Chevrolet Metro, Geo Metro, Suzuki Swift, Pontiac Firefly, and Chevrolet Sprint applications.
