Gas leak. My 2018 gmc sierra 1500 has been giving me two codes for evap leak small and large and i notice a black spot on my drive way under the gas tank wich in fact was gas. I can see the gas tank is wet but it comes from the top part of the gas tank. I been looking for recalls on this but there isnt any for this specific year of GMC sierra 1500 slt.
