Originally posted by Iron Greasel: Zebo, even if the gasoline was to ignite, it would not hollywoodishly explode in a giant ball of fire. There needs to be about 1.4% to 7.6% of gasoline in air for it to burn. The fuel stored underground would not explode, and neither would the car's gas tank. It might be dangerous if you first spill spill some gasoline on the ground, wait a few seconds for it to vaporize, and then light it.

I remember that speach from my high school Auto shop classes, they had a gutter below the floor line to catch gas fumes and channel them outside and the most interesting part to me was that lighting a match in the gutter would not work because there usually wasn't enough O2 present to ignite, let alone catch the fumes, however if you dropped a match into it it would ignite the fumes as it passed through the correct air/fuel mixture and there would be... problems.
