Detailed Description

Walker 255-1223 fuel injection pressure regulator is engineered to maintain accurate fuel pressure across changing operating conditions so the injectors receive the proper fuel supply. Correct pressure control supports stable idle quality, consistent cold starts, responsive throttle behavior, and proper air/fuel mixture management. This standard replacement regulator is built to match OE specifications for fit, pressure range, and fuel flow, making it a practical choice for Chrysler Sebring, Dodge Stratus, Mitsubishi Eclipse, and Mitsubishi Galant fuel system service.

This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.

Common Issues It Can Help Address

• Hard starting, especially during cold starts
• Fuel pressure irregularities at the rail
• Hesitation or delayed throttle response
• Rough or unstable idle
• Poor fuel economy caused by incorrect fuel delivery

Installation Notes and Tips

Verify the vehicle’s fuel system configuration before installation and compare the regulator’s port layout, mounting style, and OE reference points to the original part. Because this regulator uses push-in mounting and does not include mounting hardware, reuse or source the correct factory-style components as needed. Confirm the fuel rail connection is clean and free of debris before seating the regulator to help prevent leaks and installation issues.

Quality Assurance

Walker Products designs fuel injection pressure regulators to OE-level fit and function, with corrosion-resistant construction intended for dependable service in fuel system applications. Part number 255-1223 is built as a standard replacement for direct integration with the listed factory systems.
