This fuel tank filler pipe housing is an exact-fit replacement produced under GM specifications to restore the fuel inlet path between the filler neck and the vehicle’s fuel tank.

What does this filler pipe housing do in my fuel system?

The filler pipe housing directs gasoline from the vehicle’s filler neck into the fuel tank while maintaining a sealed connection that prevents leaks and contamination. It provides the correct alignment and attachment points so hoses, clamps, and vapor lines interface properly.

• Recreates the original inlet path between filler neck and tank for correct fuel flow
• Maintains factory attachment points for hoses and vapor canister lines
• Helps preserve a proper seal to reduce risk of fuel seepage or vapors

How does this GM Genuine Parts unit compare to aftermarket alternatives?

GM Genuine Parts are engineered and tested to the same standards used on assembly-line vehicles, so fit, materials, and mounting geometry match the original exactly. Aftermarket parts can vary in dimensions and material quality, which can lead to fitment issues or additional adaptors.

• Manufactured to GM design specifications for consistent fit and finish
• Backed by General Motors engineering and validation processes
• Reduces the likelihood of installation modifications or additional parts

Will this part fit my vehicle and how do I verify compatibility?

Compatibility depends on the vehicle year, make, model, and the vehicle’s original equipment configuration. Always confirm the GM part number 15629096 against your vehicle’s VIN or consult a GM dealer or parts catalog for an exact match.

• Use your VIN to cross-reference part number 15629096 in official GM parts catalogs
• Check mounting points and hose connections against the vehicle’s existing housing
• Contact a GM service center if you’re unsure about model-year variations

What should I expect during installation and maintenance?

Installation typically requires removal of the fuel filler neck components and possible trimming or replacement of associated clamps, seals, or mounting hardware. Because the part integrates with evaporative emission lines, careful routing and correct clamp torque are important for a proper seal.

• Often installed from underneath or behind the filler door with basic hand tools
• Inspect and replace seals or clamps as needed to ensure a tight connection
• Recheck vapor line routing and fastener torque after installation
