Last weekend, my truck died within 10 seconds of starting as I was re-positioning it do some work on another vehicle. I was able to start it after re-priming it with the hand pump, which points to a loss of prime.
Installing a clear section of fuel hose between the filter head and the CP3 intake revealed many bubbles.
One $12 o-ring and aluminum bleeder screw kit later, no more bubbles. However, there is a significant restriction still to be identified (see the static vacuum bubble on the left hand side that the air bubbles pass through). The youtubes suggest a collapsed hose or clogged fuel pickup somewhere upstream, so more work is to come.
