318 V8 running sickly

You say new fuel pump..... I have seen many new fuel pumps lately...... offshore crap..... put out way too much pressure, which the needle and seat cannot hold back. The fuel pump overpowers the float, needle and seat and floods the carb.

With it running, air cleaner off, look at and down the carb throat. You should not see any fuel coming out the carb vent or venturi booster at idle.
