Upon return home from an 8 mile total trip to the store, my daughters exited the vehicle and noted a strong gasoline odor. Upon investigation myself, I found gasoline pooling behind the engine where the main fuel line connects to a rubber hose. The pooling was on the rear of the undercarriage cover as also described below. …”
