X4XZ 12608374 Intermediate Fuel Feed Pipe – High-Pressure Pump-to-Rail Line, Corrosion-Resistant for 2.4L GM Engines

The X4XZ 12608374 intermediate fuel feed pipe is a high-pressure replacement line that connects the fuel pump to the rail to restore proper fuel delivery in compatible 2.4L Buick, Chevrolet, and GMC models.

If your vehicle is experiencing fuel delivery issues such as rough idle, loss of power, or frequent stalling, the feed pipe that runs between the high-pressure pump and fuel rail can be the culprit. The X4XZ 12608374 is manufactured to match OEM fit and function for a direct replacement on many 2.4L GM engines, providing corrosion-resistant construction and pressure-rated performance designed for modern injection systems.

How does this feed pipe restore fuel system performance?

Replacing a worn or damaged intermediate pipe removes flow restrictions and eliminates leaks that lower rail pressure. That helps the high-pressure pump maintain stable delivery to the injectors, which supports consistent combustion and engine response.

• Direct pump-to-rail connection to maintain rated pressure
• Engineered for high-pressure operation typical of modern fuel systems
• Corrosion-resistant materials reduce risk of cracks and seepage
• OEM-matching dimensions for correct alignment and sealing

Which vehicles is the 12608374 compatible with?

This intermediate fuel feed pipe is specified for a range of GM 2.4L models across Buick, Chevrolet, and GMC lines. It fits applications that use the pump-to-rail feed layout found on those engine variants, making it a suitable service part for many common models.

• Buick: Lacrosse (2010–2016), Regal (2011–2017), Verano (2012–2017)
• Chevrolet: Captiva Sport (2011–2015), Equinox (2010–2017), Impala (2014), Malibu (2013–2014), Orlando (2012–2014)
• GMC: Terrain (2010–2017)
• Check VIN and part cross-reference for exact match before purchase

What materials and construction features ensure reliability?

The 12608374 pipe is made from robust, corrosion-resistant alloys and fittings engineered to tolerate high pressure and thermal cycling. These construction choices reduce the likelihood of premature failure under typical driving conditions.

• High-strength tubing resists cracking under pressure
• Corrosion-resistant surface treatment for long life
• Precision-formed ends for leak-free connections to pump and rail
• Tested to meet pressure and fitment expectations for replacement parts

How difficult is installation and what support is available?

The part is designed to be a direct-fit replacement to simplify installation and minimize labor time. While many technicians complete this swap during routine fuel-system service, basic mechanical experience and proper safety practices are required when working with high-pressure fuel lines.

• OEM-matching dimensions for bolt-on replacement
• Recommended for installation by qualified technicians or experienced DIYers
• Follow vehicle-specific service manual steps and fuel-system depressurization procedures
• X4XZ provides 24-hour customer service and a one-year product service window

Who is this for: The X4XZ 12608374 intermediate fuel feed pipe is intended for owners and mechanics addressing fuel delivery faults on GM 2.4L vehicles who need a pressure-rated, corrosion-resistant pump-to-rail replacement. Choose this part if you require an OEM-dimensioned, durable feed line to restore consistent fuel pressure and return the engine to reliable operation.
