PO455 evap code
 
Hello, My '05 pathfinder is displaying a EVAP PO455 code (large leak). I've replaced the gas cap and visually inspected the lines and they look like they are in good shape. I did notice significant corrosion (green in color) on two aluminum colored lines (fuel lines?). It looks like they were covered with a piece of rubber 2 in wide and fastened with zip locks. The corrosion has eaten through the rubber. If these are leaking fuel lines can this result in the PO455 code?? thanks

The green corrosion you see on the aluminum lines is actually coolant leaking from your rear heater lines.
The po455 is probably a stuck vent control valve on the evap canister.
