I recently had a new fuel pump and filter put on my car. The mechanic had to look at my car twice after the initial work, due to the strong smell of gas fumes. I have taken my car to AutoZone for a diagnostic reading. I have made sure the fuel cap is on and correct. One of the employees at AutoZone said it may be a hole in the gas canister, right at the entry site or it could be a small crack in one of the fuel line hoses. When I put gas in my car, the smell is not as bad as it has been, but I can still tell it is leaking somewhere and my check engine light is still on. Has anyone had this problem? Any suggestions?
