Where is the fuel tank switch for the Buick Envision?
1 Answers
The Buick Envision does not have a fuel tank switch. Simply put the vehicle in Park (P) and press the outer part of the fuel tank to open it. Fuel tanks can be divided into two types: open and closed. An open fuel tank has its liquid surface in contact with the atmosphere, and an air filter is installed on the fuel tank cap. More details are as follows: 1. Open fuel tanks have a simple structure and are easy to install and maintain, making them commonly used in hydraulic systems. Closed fuel tanks are typically used for pressurized fuel tanks, filled with a certain pressure of inert gas, with a charging pressure of up to 0.05MPa. Based on shape, fuel tanks can also be classified as rectangular or cylindrical. 2. Rectangular fuel tanks are easy to manufacture and convenient for placing hydraulic components, hence widely adopted. Cylindrical fuel tanks offer high strength, lightweight, and easy cleaning, but are harder to manufacture and occupy more space, often used in large metallurgical equipment. 3. After a period of vehicle use, conduct a thorough cleaning and inspection of the fuel tank. When cleaning, rinse the interior with hot water, then dry it with compressed air to remove gasoline vapors inside. Next, immerse the fuel tank in a 10% sodium hydroxide solution, followed by rinsing the interior and exterior with running water. Alternatively, clean with a 5% boiling caustic soda solution, then rinse with hot water.
