2.4 CEL throws code 0455-Large evap leak and DIC warns to Check gas cap Peplaced cap.Still throws warning. Donbrew suggests to check cracked or something disconnected. Searched for photos involving evap system but could not find. Only thing that looks suspicious is a hard plastic tube(1/2" ID + -) that runs along fuel filler pipe. Connects to a small beer can shaped canister. Followed it up towards gas cap and tube is open ended with a smooth diagonal cut on end. What you would expect a vent pipe to look like. Before I tear wheel well out, just wondering if this is normal or did something break off or come loose. Thanks in advance.
