ACDelco 55570149 Multiport Fuel Injection Fuel Rail GM OE Replacement

The ACDelco 55570149 is a GM Original Equipment Multiport Fuel Injection Fuel Rail engineered to exacting OEM standards as a direct replacement for select GM vehicles. As a true OE part, it is designed, engineered, and tested to the same rigorous specifications as the component originally installed at the factory.

The fuel rail serves as the primary fuel delivery manifold in a multiport fuel injection system. It connects to the fuel injectors mounted just above the intake manifold and delivers pressurized fuel to each injector, which then atomizes the fuel into the combustion chamber to be mixed with air for efficient combustion.

Key Features:

• Genuine GM Original Equipment part — the same component validated for use in GM vehicles
• Engineered and tested to rigorous GM quality and durability standards
• Direct OE replacement for a precise, no-modification fit
• Backed by General Motors for confidence in quality and reliability
• Compatible with multiport fuel injection (MPFI) systems

Choosing a genuine OE fuel rail helps ensure proper fuel pressure delivery, consistent injector performance, and long-term reliability compared to generic aftermarket alternatives.
