It's not good but you possibly can overcome this.
That's not to say guaranteed though.
First, completely drain the fuel tank(s). You may have to siphon if you don't have a drain point. Get as much of the gasoline out as you can. Drain fuel rom the HFCM too. Use a turkey baster to get fuel out of the upper fuel filter reservoir. Allow the system to ventilate open to atmosphere for a day if it isn't looking like rain. Get new fuel filters too. Refill with diesel and the cetane boost from Ford or an aftermarket cetane boost but the Ford stuff is very good - use the proper mixture according to the label. The gasoline is most definitely in the fuel lines, the injectors and throughout the system though so you could have some fouling. The 2005 Ford 6.0L does not have a diesel particulate filter so there is one place less to worry about damaging. The fuel pump is durable. The injectors could be damaged but don't count them out either. After refilling and allowing the system to prime several times you will have rough running for a while to be sure. I suspect that things will smooth out after several tanks WITH additive.
I hope this helps. It's better than just saying you have to buy a new engine though.
