Gas will bubble back when filling the tank if the gas is going in too fast. In most filler tubes for newer vehicles, there is a mechanism that prevents siphoning. If the gas gets trapped in this mechanism, it cannot handle the volume and it might spit some of it back.

Gas tanks don't release air when refueling. When you remove the gas cap, any pressure in the tank is released. If you're referring to gas "spitting" back out when pumping, try squezzing the pump handle a little less to slow the flow of gas into the tank.

if you get splash back when fuelling, u need to fuel slower so as the air being displaced by fuel in the fuel tank can escape past the fuel going in splash back , is simply a big air bubble moving out of the fuel tank we had a f250 pickup that did that we remedied it by driving rear right wheel onto a block while fueling. this tilted the truck away from filler and allowed air to escape more easliy


How much is 15 liter for gas tank?

The cost of filling up a 15-liter gas tank depends on the price of gas per liter. You would multiply the price per liter by 15 to get the total cost. For example, if gas costs $2 per liter, filling a 15-liter tank would cost $30.
