How to open the fuel tank cap of an old Buick GL8?
2 Answers
The method to open the fuel tank cap of an old Buick GL8 is: locate the inner cap of the vehicle, as the fuel tank cap consists of an inner and outer cap. The outer cap is electronically controlled with a button-operated lever located on both sides of the driver's seat, featuring a fuel pump icon. Press or pull the lever, and the fuel tank cap will open automatically. To open the inner cap, you must first open the outer cap to access it. The inner cap is closed by turning it to the right and opened by turning it to the left; turning it left completes the opening process. The Buick GL8 has a length of 5213mm, width of 1847mm, height of 1745mm, a wheelbase of 3079mm, a front track of 1586mm, a rear track of 1590mm, and a fuel tank capacity of 95L.
Last time I drove my old Buick GL8 to refuel, the fuel tank cap opening method was quite simple: there's a small lever under the driver's seat, on the inner frame of the left door. Just give it a gentle pull to open the cap. I remember one winter when the cap was frozen, pulling hard didn't help—I had to turn on the car's heater for a few minutes to warm it up before trying again. Normally, avoid yanking it forcefully to prevent the cord from breaking or the handle from getting damaged. During maintenance, regularly check if the pull cord is aging. The mechanic mentioned many cases of rusted cables in old GL8s, and replacing the cable makes it smooth again. Always turn off the engine before operating to ensure safety, and never start the engine while refueling. Remember the location so you don’t look in the wrong spot.
