The official notice
Defect
On certain vehicles, a particular type of spider may weave a web in the evaporative canister vent line which may cause a restriction in the line. If this occurs, the fuel tank pressure may become excessively negative when the emission control system works to purge the vapors from the canister. As the canister is purged repeatedly during normal operation, the stress on the fuel tank may eventually result in a crack causing a fuel leak. Fuel leakage, in the presence of an ignition source, could result in a fire causing injury and/or property damage.
Safety Risk
No risk description available.
Remedy
Dealers will inspect the canister vent line and replace it with a line containing a filter. If a web is found in the old line, the fuel tank will also be replaced
