There is normally a bubble in the line feeding the pre-filter when the engine is off, so do not be concerned about that one at all. Make sure all of the other lines are secured and the clips are correctly positioned (they need to be loose, not pressed up against their ends). If you still have some bubbles in the lines it may just be the residual air in the system from opening it up...take it for a drive and see if it clears up some after that...it might just be normal.
You didn't mention replacing the o-ring at the prefilter housing itself...this is the most likely cause of air in the fuel system...did you replace that one???
