How.do I get fuel to the first filter in my 2005 ford f250 6.0

If the pump is operating correctly then you should be able to cycle the key 2-3 times and it will prime the lower and upper filter. after fuel filter change it may take a few times of cranking the engine over to get all of the air out of the lines. also try leaving the key in the run position for a few min. it should prime just fine like i said as long as the pump is operating properly. if you ran it out of fuel it will take a very long time to crank and prime the vehicle without the correct 6.0L fuel adapters.

Not to be a jerk, but you look in the manual. If you don't have one, you order one from any number of online suppliers who will sell you one. I did that for my 2003 Chevy Silverado pickup. If you're going to keep the car, you will eventually need it anyway. . .
