Gas expands and contracts a good deal with temperature change and it
increases the moisture in you tank when it "breathes".
How much do you think gasoline expands and contracts with temperature
change?
1% ? 10% ? .01% ? How much is a "good deal"? Please be clear on the
coefficient of thermal expansion for liquid gasoline versus gasoline vapors.
