Ok, here's another one guys
Went to fill up today and when I unscrewed the gas cap there was a crazy rush of air that blew out of the filler. What would cause this type of pressure build up?

Faulty venting thru the vapor recovery canister. With today's systems, that's the only place air can enter or leave the tank, unless you take the cap off.

Thats the same one under the front bumper that most people move into the engine bay right? I'll take a look at it, thanks.
I did just have a tank strap break, maybe the line to the can came undone or kinked.
