I have a 2009 Dodge Ram 1500 Hemi 4X4 with a 5.7 L Engine . I recently got a fuel pump replacement and oil change. Now I can smell gas!?

Update: there was also a symbol(gas cap) that popped up in the dash, also I noticed that my truck has been burning a lot of fuel, especially when it is idling. I checked for any leaks underneath, or if the gas cap was loose but nothing! any suggestions would be greatly appreciated!!
