Just wanted to post a followup for the next guy down the road with similar issues. Here are the pics of the crack. At first it looks like a normal line in the casting but its about the same place as the spot in the secondary throat where the fuel was seeping through. I replaced only the main body and reused everything else. Made no float adjustments... just swapped everything over. The car runs great now with no flooding. Even the fuel pressure is staying up after I shut the engine off. It looks like the fuel bowl was emptying and opening the needle and seat, releasing the pressure.
