    GM 12677002 is a fuel rail crossover tube (also called a high-pressure fuel feed intermediate pipe or "S" pipe). It handles high fuel pressure between the fuel rails on Gen 5 small-block engines.

    Replacement: Often swapped out during major engine work like camshaft upgrades or Active Fuel Management (AFM/DOD) deletes.

    One-Time Use: The factory hard-line style crossover is typically designed as a one-time-use seal component, requiring a fresh replacement part anytime the fuel system or intake manifold is disassembled

    GM 12677004 is an intermediate high-pressure fuel feed pipe used on modern direct-injection GM V8 engines (such as the 5.3L and 6.2L Gen V LT/L83/L86 engines) to link the high-pressure fuel pump (HPFP) to the fuel rail system.
    Function: Transfers and maintains high fuel pressure safely between the mechanical fuel pump and the fuel rails.

    Material: Corrosion-resistant stainless steel built for high-pressure under-hood conditions.

    Replaces Older Part Numbers: Supersedes previous GM part numbers 12618337, 12673077, and 12679191.
