    gas tank pressure vacuum check valves

    How does a gas tank build pressure? I understand the vacuum portion through the consumption of fuel and the void that it leaves creates the vacuum, but what builds the positive pressure? Is it from the general sloshing of the fuel when riding?

    When fuel gets warmer, it will expand.

    Pressure is created by a one way check valve that allow ambient air pressure to enter the tank but not escape.

    The pressure is created from heat.

    And.......the gas vaporizes from heat and agitation
    And......most things expand with heat, but what dosnt and lead to formation of life? Ice, it floats and that was the key to it all

    This would be the case for atmospheric pressure, but would not apply in a sealed environment such as a gas tank
