The evaporative canister vent line runs from a charcoal-filled canister that cleans air coming out of the gas tank. Blockage of the line can prevent air from getting into the gas tank as the gasoline is used, resulting in negative air pressure inside the tank. That can lead to a crack in the gas tank and the possibility of a fire.

There have been 20 reported cases of spider infestation in the Mazda6 -- all have been in cars with 4-cylinder engines, none with V6's. No actual fires are known to have been caused by the spiders, according to Mazda's letter.
