Of course, my mistakeIt won't leak from there even IF the body is distorted because the fuel level should NEVER reach the upper gasket level unless-- 1) Float is stuck. 2) Needle and seat are damaged or have debris on the seat. 3) Float is improperly set for rise setting. 4) Most likely, fuel pressure overwhelms float weight.
Just lower fuel pressure to 3# or less and if it still leaks, something is wrong with the float / needle / seat arrangement as set-up. Pretty simple to diagnose.
