How do you bleed a Mercedes c250 fuel system?

To bleed the fuel system on a Mercedes C250, first ensure the vehicle is off and safely secured. Locate the fuel pump relay in the fuse box and remove it. Turn the ignition to the "on" position for about 10 seconds to activate the fuel pump and build pressure in the system, then turn it off. Repeat this process a few times, then reinsert the fuel pump relay, and start the engine to check for proper fuel delivery and ensure there are no leaks.
