I measured the the oil level in this reservoir and found it to be 6.5" below the top of the reservoir. Tonight when I get home, I will try adding oil to this reservoir.
I hope that fixes your problem. It is a terrible feeling when your truck won't start and you have work to do. I would recommend watching all of PowerstrokeHelp's videos. He is pretty through and knows his strokes. If you don't have proof of service records for your truck, I would suggest that you go through PSH's longevity series and perform the work you can so that you know it has been done.
Good luck.
