Yesterday I filled up my 01 Z06 tank at a chevron. After I got home I smelled gas fumes around the gas cap. I investigated and found a leak on the passenger side gas tank. I jacked up the car and removed the tank covers. A few drops of gas dripped on the floor. I traced it and found the trail leading to the top. I cant see where it was leaking from exactly.

Anyone had this problem before? How'd you fix it?
