It's not coming out of a hole. It's coming out of the end of the vent hose. Could this be cause by too much tank pressure maybe?

My ford fusion is giving me the same issues and error codes. If you find a solution to this issue, please hit me up. My mechanic does not know what to recommend. He only wipes out the code electronically. @guruk3B4z
