06 Cobalt LS Gas Leak

The car has a heavy gas leak that seems to be coming from the driver side gas tank vent, there is no gas on the fuel pump. Codes were pulling p0455, and p0496. Already replaced the purge solenoid and the vent solenoid. At wits end at this point. Any help would be appreciated!

Usually the gas leak is one or two gas lines that run near the rear tire driver side that have a covering with silver material for heat, water gets trapped in there and rust the lines the fix is easy cut out the Rusted lines 1 2 or 3 ft long and use rubber gas line and hose clamps.
