ACDelco Gt329 Gm Original Equipment Fuel Tank Cap

The ACDelco GT329 is a GM Original Equipment fuel tank cap designed, engineered, and tested to rigorous standards and backed by General Motors. This black plastic fuel tank cap is sold individually and serves as a direct replacement for the original factory component on GM vehicles including Buick, Cadillac, Chevrolet, GMC, Saab, and Saturn models.

Key Features:

• Rubber gasket provides a liquid-tight seal to keep fuel in and water and dirt out
• Check valve regulates air pressure by allowing air in or out depending on pressure inside the tank
• Pressure relief valve allows excess pressure to escape, reducing the risk of fuel leakage and damage to the fuel system
• Sealed design reduces vapor emissions and prevents fuel loss
• Includes tether assembly to prevent cap loss
• Made to OEM standards for reliable function and hassle-free service

ACDelco GM Original Equipment parts are the true OE parts installed during production or validated by General Motors for GM vehicles. This fuel tank cap helps maintain proper fuel system pressure, which is crucial for optimal engine performance and preventing diagnostic trouble codes related to evaporative emission system leaks.
