Make sure your gas cap is sealing tank properly. Also you can try smoke testing the gas tank and see if any evap lines are cracked on top of tank or near frame rail. If this is all good, you need to make sure your leak detection pump which should be in passenger rear wheel well. Make sure pump comes on to pressurize tank and also that it is not cracked or broken.
