The auxiliary fuel tank is supplied by negative pressure. If you want to use the gasoline in the auxiliary fuel tank, you must first ensure that the main fuel tank is relatively full, and then run the motorcycle. Oil is pumped to the main tank.
▶Instructions:
After the auxiliary fuel tank is installed, first fill up the main fuel tank, then fill up the auxiliary fuel tank, and then it can be used normally. At this time, the fuel gauge of the original motorcycle will not drop until the fuel in the auxiliary fuel tank is used up. When you find that the fuel gauge has dropped by one level, it means that the gasoline in the auxiliary fuel tank has been used up. Start using the gasoline in the main fuel tank and continue to run until the main fuel tank. After the fuel tank prompts, just fill up the two fuel tanks.
