I don't think you need to bleed it. I've run out of gas a few times with F.I. and never had a problem. I wonder if you may have stired up something from the bottom of the tank . Might be time to check the screen in the tank and a new filter aswell . Could also turn out to be some thing totaly unrelated to this incident , points , vacume hoses, etc. Hope this helps.
btw , that 7mm srcrew is for testing fuel presure.( remove it , hook up gage, run motor, check presure)
