Traditional port fuel injection runs at say +/-40psi, with the fuel rail pressurized by a traditional fuel pump. If you've ever heard a quick twang/whine underneath or behind you when you turned the key to ON before cranking, that's the fuel pump pressurizing.

Direct injection like the Stinger and other modern cars have run at 2000+ psi, which requires a High Pressure Fuel Pump. All that pressure means that instead of being electric, they're typically mechanically driven by a camshaft lobe, so they have to be on top of or beside the engine. And they often sound like lifter tick or other valvetrain noise (which makes sense, as they're basically a 25th valve).

The thing on top is the HPFP (connected to the fuel rail and direct injectors below). The camshaft would sit just below the black spring at the bottom of the pump, with an extra cam lobe spinning around and pushing the plunger/piston up. That's the clatter/tick you hear:


Here's another example from an Ecoboost:
