Carb not getting Fuel

Your fuel pump at 3 pounds sounds low, most pumps I`ve read are in the 6-7 pound range. You still might want to check to see if your new pump is the proper one and if it`s pumping like it should. You can also check for leaks in the fuel line, a clogged fuel filter, or that the tank is vented properly. Also check the pick-up tube and sock for any obstructions.
