Yes, aside from an annoying check engine light from a false EVAP System failure code.
The fuel system in your car is a sealed system that traps harmful gas fumes. If the gas cap is left off then gas fumes are able to escape from the system. When this happens, a self-test of the performance system detects this “leak” in the EVAP (Evaporative Emissions System) and the check engine light comes on, and a code is stored.
A flapper valve is built into TODAY's fuel filling systems. This valve stops reverse flow of fuel out of the tank. If you stood the vehicle on its head, gas would not flow out of the tank because the flapper valve is an anti-roll valve.
