It is the square cross-sectioned 'tube' that runs along the top of your cylinder head. It is supplied pressurized fuel by the pump. The pressure is regulated by the pressure regulator.
On the rail are mounted injectors, which are basically little electrically operated faucets, that open as required to let fuel into the intake manifold, from where the fuel is swept by inflowing air into the cylinders for ignition.
All gasoline cars should have a fuel rail.
