Engine light came on with evap leak code. Small leak at first then included large leak code later. Also began to notice strong gas smell outside vehicle after fueling. Turned out the fuel pump ring that holds down and seals fuel pump to fuel tank had cracked. Over time the split became larger. When tank was filled, raw fuel would leak out around pump on top of tank. Which also happens to be right under the rear seat where me kids sit. Replacement was expensive because the ring could not be removed from under the seat. It required dropping the tank to repair. Mechanic felt it was a stress crack. The fuel pump had never been worked on before. The original ring was installed at the factory.

There was a strong fuel smell that was occurring on both the inside and outside of my car every time I filled my car up. I took to my the mechanic and it was found my fuel tank was leaking in 2 spots. One was part of the gas tank that vents the fumes - that seal was leaking and the other was part of the locking ring that is on the gas tank itself was cracked.
