69 340 AVS fuel leak

I had to remove the tin slosh baffles and trim them , put them back in. Some corrective bending on the float tangs. Those 2 float to needle hooks were the last pieces to go on. Wasn't sure I could use them for a time.
There is a check ball for accererater pump ?
Correct size ball seating properly ? To give that steel ball a tap or 2 with a drift and hammer can correct a potmetal seat (tip of the day). LOL
Have you attempted to run it breifly and snatch the top off while on the engine. If the bowl is over flowing or the acc. pump is leaking down.. you'll see it.
thinking out my fingers again. Good luck.
