Walker Products 255-1020 Fuel Injection Pressure Regulator

The Walker Products 255-1020 is a direct-fit fuel injection pressure regulator engineered to restore proper fuel system operation. Fuel injection pressure regulators control fuel pressure within the fuel rail, ensuring the correct volume of fuel is delivered to the injectors across all operating conditions — from cold starts to wide-open throttle.

Key Features:

• OEM-matched specifications — designed to meet or exceed original equipment manufacturer standards for fit, form, and function
• Direct-fit replacement — matches the exact dimensions and connector configuration of the factory regulator, requiring no modifications
• Corrosion-resistant construction — built to withstand continuous exposure to fuel and demanding engine bay environments
• Precision fuel pressure control — maintains accurate fuel pressure for proper air/fuel mixture, supporting smooth idle, strong throttle response, and reduced emissions
• ISO 9001/IATF 16949 certified manufacturing — produced in a certified facility with rigorous quality control standards
