I went out and cycled the pump, listening as I went. I cleared the Schrader valve one more time and it hissed and bubbled a bit, then a solid stream of fuel came out.
As WP suggested, I bled the high pressure banjo bolt and it hissed and popped. Once steady fuel was coming out I closed it up again. I then cycled the key 2 or 3 more times and bled both Schrader and the HP banjo bolt again. The banjo had a very quick pop and fizz but then straight fuel. I closed it off. I cycled the key 2 more times, listening for burbling fluid but I heard nothing.
I turned the ignition and with only a moments hesitation, she fired up right away. I waited for it to shut down - AND IT DIDN'T! She continued to run! I ran the truck for 15 minutes and she purred like a kitten...
WP was right, all my jigging around forced air into the HP side of the system. I've read numerous threads on this problem but none with as much detail as what everyone here provided. I hope my experience will help others in the future if they get air into the system when changing out their own fuel filters.
What I learned:
1. Do your own basic maintenance. Nothing gives peace of mind than doing it yourself and seeing with your own eyes what's going on. The fact that I saw the GUNK that built up in the lower filter was priceless. Now I can address this before it becomes a $10,000 problem. These things are really not that complicated and if you read around the topic before you attempt it, you're already 1/2 way home. If you get into trouble, make sure you allow a day or two of grace and you can probably bail yourself out with help from friends on dieselstop.com.
2. DO the maintenance. It really pays to read around the basic maintenance topics on this site. Lots of guys, just like you, are doing it themselves - often making mistakes along the way. I just learned how to do my own fuel filters AND how to bail myself out when air gets into the system. Find out what needs to be done and then DO IT when the interval comes up.
3. GIVE BACK TO THIS SITE! I've read so many posts that never have a conclusion. I know that once you solve the problem it's easier to forget about it and move on, but how you solved your problem is important to others and they can learn from your mistakes. I do my best to follow up with my posts and offer closure, I hope this helps others. When you are dealing with a $35,000 truck, some of these things can be stressful, especially fuel system issues.
Thanks to everyone who took the time to respond, it was appreciated. The few minutes you took to share your experience and wisdom was well received. If you were here, I would treat you to a cold one and a few laughs.
