It can take a bit. But dribbling fuel is not bled. It'll run fuel out of the lines.
Try loosening 1,3 and 4 only. I mean loose enough to pull the nuts back. Have a helper watch under hood.
Before that, confirm the lift pump has purged all the air out of the lines to the VP. Bump the starter and allow the pump to run until it stops. Do this several times. 3-6 at least. DO NOT CRANK OVER DURING THIS!!!
When you think you have the truck ready to start, turn the key on and bump the starter. When the pump begind to run, crank for 10-15 seconds or until your helper sees fuel coming out of a line or two. Also, do not allow the truck to start.
Tighten the lines that have heavy fuel. When all three flow fuel, then you can go for it.
When everything is tight, crank the key. Do NOT touch the throttle.
It'll take some cranking, but should eventually start. Some start easier than others. The Electric pumps can be a bit more work. On the trucks we have done cam swaps and 12V pumps on, we don't have to bleed ANY part of the system. Just crank and it lights.
