Unhappy How to bleed air from fuel lines?

I have a 2003 F-350 SRW with the 6.0L. I was putting some fuel additives in my tank and the plastic seal jumped in too. A few days later I lost almost all power. i ended up replacing the fuel pump and both fuel filters and the engine is almost back to normal. Once the engine is above 2500-3000 rpm and the turbo kicks in I have all the power but from a dead stop it is very slow to get moving, even when I am in park the engine will not spool as quick as before. I think I may have air in the lines. I have loosend the fuel filter under the hood and then turned the fuel pump on and screwed it down to try to force any air out. It seemed to have much better respone as soon as i fired it up but when I drove it was still sluggish from a stop. I went back to park and then it would not spool up as quick as it should.

What is the best way to blled air from the fuel lines?

Any other ideas?

Exactly, it seems that if its still having problems after you've run it a while it might be something else.
