Would you fly this Aircraft?

Fuel has weight, a little less than .5 pounds per foot of
distance.

I've never heard it expressed quantitatively thus. Could you elaborate?
Weight is a function of volume, and pressure would be a function of
height.

weight is a function of density, volume does not matter when
pressure is measured in PSI.

The density of gasoline changes much? Weight is mainly a function of
the quantity of matter present (mass) and the gravitational field it's
in. Given liquid gasoline and the earth, volume is a good stand-in for
weight.

Pressure depends on the height of a column of fluid in a gravitational
field. Is that what you meant?

Gasoline changes density with the blend and it also changes
with temperature. The "standard" 6 pounds per gallon (US)
is just an average. Yes, the distance the weight a fluid
(including air) acts under gravity determines the pressure.
Volume is a measure of space, density is a measure of mass
per unit space.

If you have a tank with a fixed amount of fuel, and the temperature rises,
the fuel will expand. However, the presure at the bottom of the fuel tank
will not increase if the tank is properly vented.

I think what he's referring to is called "head pressure".
