Where is the fuel tank cap switch for the GL8?

[DelJoshua]

There are two scenarios for the fuel tank cap switch of the Buick GL8: 1. Below the driver's seat in the main cabin: You can pull it outward by hand to open the fuel tank cap. 2. Inside the fuel tank cap: Locate the fuel tank cap and press it slowly to open the fuel tank. Below are some maintenance tips for the car fuel tank: 1. Regularly clean the fuel system: The fuel tank is designed to be waterproof and maintain temperature. If the car idles for extended periods, the fuel system should be cleaned or the filter replaced once it reaches 30,000 kilometers. Otherwise, blockages in the fuel system can cause high pressure in the fuel tank, leading to shaking while driving. High pressure can also cause the fuel tank to crack, potentially resulting in fuel leaks and increased fuel consumption. 2. Tighten the fuel tank cap: During summer, high temperatures cause fuel and water to evaporate quickly. Ensure the fuel tank cap is tightly closed to prevent fuel line leaks. Regularly check the water level in the radiator, the oil level in the crankcase, the brake fluid level in the master cylinder, and the electrolyte density and level in the battery. If any of these levels fall below the normal range, promptly add or adjust as necessary.

I remember the fuel filler cap switch location on the Buick GL8 is quite interesting, with significant variations across different model years and configurations. My 2016 model has a small square button on the instrument panel below the steering wheel on the left side. However, my neighbor's newer 653T model is more intelligent—it doesn't require a dedicated switch at all; you can simply press the fuel filler cap to pop it open when the vehicle is unlocked. Once, a friend driving an older GL8 Firstland searched everywhere for the switch and finally found a plastic pull handle on the left side of the driver's seat carpet. I recommend checking your specific GL8 model first, as the owner's manual provides the most accurate information. Also, a friendly reminder: pay attention to the fuel grade label near the filler neck when refueling. Some models require 92-octane gasoline, and using higher-octane fuel can actually harm the engine. Don't fall for gas station attendants pushing expensive premium fuel—it's often unnecessary.
